INTRODUCTION

THANK YOU!

The TS-870S Intelligent Digital Enhanced Communications System was developed by a team of engineers

determined to continue the tradition of excellence and innovation in KENWOOD HF transceivers.

Taking maximum advantage of Digital Signal Processing technology, the TS-870S introduces operating tools like Auto Notch, Beat Cancel, and Noise Reducer. When coupled with its IF Shift, Noise Blanker, and Advanced Intercept Point functions, you will enjoy a critical edge as you fight QRM and QRN in the new solar cycle. In addition, the convenience of a built-in RS-232C connector can transport your shack into the world of remote transceiver control via computer.

But first, tame your ego and enthusiasm temporarily — read every page of this book. Consider this manual to be a personal tutorial from the designers; allow it to guide you through the learning process now, then act as a reference in the coming years. Though user friendly, the TS-870S is technically sophisticated and some features may be new to you. Your reward for your diligence will be mastery of the TS-870S in the shortest time possible with maximum fun.

As you continue exploring Amateur radio, thank you for allowing the KENWOOD family to join you in this chapter of your adventure.

DSP — MAXIMUM SIGNAL/ MINIMUM NOISE

The TS-870S design includes a 2-channel Sigma-delta A/D converter, two 2-channel Sigma-delta D/A converters, and a 2-channel advanced single-bit D/A converter. Operating at a clock rate of 40 MHz, DSP works for you whether you use SSB, CW, FM, or any other mode. The adaptive filter functions include Auto Notch, Line Enhance, and Beat Cancel.

DSP is the most effective way of using current technology to separate what you want from what you don’t want. While receiving, you hear the most signal and the least noise. While transmitting, you emit only the desired audio components of the modulation without adding distortion. The transmit equalizer combines high boost, bass boost, and comb filter functions to further improve your signal.

With DSP, you will hear clear receive signals that are covered by noise on conventional equipment. The enhancement of the receive signal is due to the reduction of atmospheric and white noise, and to rejection of adjacent frequency interference including heterodynes. This capability of DSP to “clean up” the environment surrounding the desired signal has a significant effect. The signal you are trying to receive will seem stronger and clearer even though the S-meter reads the same. Those tired of listening to interference of all kinds while operating may think a little magic is being used.

FEATURES

• Employs Digital Signal Processing (DSP) techniques to significantly improve the quality of received and transmitted signals.

• Includes extensive user-adjustable digital and analog filtering functions for combating all forms of received interference.

• Allows total customization of transmitted audio through use of functions such as Transmit Equalizer.

• Introduces a built-in RS-232C port for directly interfacing to a computer. Supports computer control of functions at a user-selectable transfer rate between 1200 and 57600 bps inclusive.

• Streamlines function setup by presenting an intuitive Menu System for function configuration and control.

• Conveniently allows ANTENNA1/ANTENNA2 selection from the Front Panel.

• Directly addresses CW operators’ interests by including a full-function K-1 Logikey complete with test mode, semi-automatic mode, and popular keyer emulations. The Rear Panel is equipped with a PADDLE jack and a KEY jack for connecting a paddle, an external keyer, or a keyboard.

•Provides an antenna tuner that can easily be inserted into or removed from the transmit and receive paths.

INSTALLATION

|nstall and connect an antenna system {page 2}.

Install a ground system that satisfies DC and RF grounding requirements {page 3}.

Install lightning protection to protect the antenna system, your personal safety, and your property {page 3}.

ANTENNA CONNECTION

The type of the antenna system, consisting of the antenna, ground, and feed line, will greatly affect the successful performance of the transceiver. Use a properly adjusted 50 Ω antenna of good quality to let your transceiver perform at its best. Use a good-quality 50 Ω coaxial cable and a first-quality connector for the connection. Match the impedance of the coaxial cable and antenna so that the SWR is 1.5:1 or less. All connections must be clean and tight.

While the transceiver’s protection circuit will activate if the SWR is greater than 2.5:1, do not rely on protection to compensate for a poorly functioning antenna system. High SWR will cause the transmit output to drop, and may lead to radio frequency interference to consumer products such as stereo receivers and televisions. You may even interfere with your own transceiver. Reports that your signal is garbled or distorted, especially at peak modulation, may indicate that your antenna system is not efficiently radiating the transceiver’s power. If you feel a tingle from the transceiver’s cabinet or the microphone’s metal fittings when you modulate, you can be certain that, at the least, your coax connector is loose at the rear of the radio and, at the worst, your antenna system is not efficiently radiating power.

Connect your antenna feed line to ANT 1. If you are using two antennas, connect the second antenna to ANT 2. The EXT RX ANT jack can be used to connect a separate receiver. Note that this jack must be enabled by Menu configuration {pages 24, 27} before it can be used.

CAUTION:

◆

Transmitting without first connecting an antenna or other matched load may damage the transceiver. Always connect the antenna to the transceiver before transmitting.

◆

Use a lightning arrestor to prevent fire, electric shock, or damage to the transceiver.

Install and connect a DC power supply {page 3}.

GROUND CONNECTION

At the minimum, a good DC ground is required to prevent such dangers as electric shock. For superior communications results, a good RF ground is required, against which the antenna system can operate. Both of these conditions can be met by providing a good earth ground for your station. Bury one or more ground rods, or a large copper plate under the ground, and connect this to the transceiver GND terminal. Use heavy gauge wire or a copper strap, cut as short as possible, for this connection. Just as for antenna work, all connections must be clean and tight.

LIGHTNING PROTECTION

Consider carefully how to protect your equipment and your home from lightning. Even in areas where lightning storms are less common, there is usually a limited number of storms each year. Take the time to study the best way to protect your installation from the effects of lightning by consulting reference material on the subject.

The installation of a lightning arrestor is a start, but there is more that you can do. For example, terminate your antenna system transmission lines at an entry panel that you install outside your home. Ground this entry panel to a good outside ground, and then connect appropriate feed lines between the entry panel and your transceiver. When a lightning storm occurs, you can ensure added protection by disconnecting the feed lines from your transceiver.

CAUTION:

REPLACING FUSES

If the fuse blows, determine the cause then correct the problem. After the problem is resolved, only then replace the fuse. If newly installed fuses continue to blow, disconnect the power plug and contact your dealer or nearest Service Center for assistance.

DC POWER SUPPLY CONNECTION

In order to use this transceiver, you will need a separate

13.8 V DC power supply that must be purchased separately. DO NOT directly connect the transceiver to an AC outlet! Use the supplied DC power cable to connect the transceiver to a regulated power supply. Do not substitute a cable with smaller gauge wires. The current capacity of your power supply must be 20.5 A or more.

CAUTION:

◆

Before connecting the DC power supply to the transceiver, be sure to switch the transceiver and the DC power supply OFF.

◆

Do not plug the DC power supply into an AC outlet until you make all connections.

■ Keys and Keyboards for CW Operation (PADDLE and KEY)

For CW operation using the internal electronic keyer, connect a keyer paddle to the PADDLE jack. For CW operation without using the internal electronic keyer, connect a straight key, semi-automatic key (bug), electronic keyer, or the CW keyed output from a Multimode Communications Processor (MCP) to the KEY jack. The jacks mate with a 6.0 mm (1/4") 3-conductor plug and a 3.5 mm (1/8") 2-conductor plug respectively. External electronic keyers or MCPs must use positive keying to be compatible with this transceiver. Use a shielded cable between the key and the transceiver.

Note:

Due to the full-featured functionality of the internal electronic keyer, you may decide it’s unnecessary to connect both a paddle and another type of key unless you specifically want to use a keyboard for CW. It’s recommended that you become familiar with the internal keyer by reading “ELECTRONIC KEYER” {page 32} before making your decision.

2 INSTALLATION

■ Computer Interface (COM)

This connector allows you to directly connect a computer or dumb terminal by using an RS-232C cable terminated with a female 9-pin connector. No external hardware interface is required between your computer and the transceiver if your computer has an unused RS-232C serial communications port. See Appendix D on page 83 for information relating to this connector.

■ RTTY Equipment (RTTY and ACC 2)

To operate Frequency Shift Keyed RTTY, connect your RTTY equipment as shown below. Connect the RTTY key output from your RTTY equipment to RTTY, and connect the demodulation input of your RTTY equipment to ACC 2, Pin 3. By default, a short condition generates a space; an open generates a mark. However, this can be reversed via Menu settings.

Do not share a single power supply between the transceiver and the RTTY equipment. Keep as wide a separation as possible between the transceiver and the RTTY equipment as practical to reduce noise-pickup by the transceiver.

■ Linear Amplifier (REMOTE)

The REMOTE connector allows connection of an external transmit power amplifier. If using an amplifier, confirm that Menu No. 51 (LINEAR) is set to “1” (Fast) or “2” (Slow) {pages 24, 27}. This Menu item controls the linear amplifier TX/RX relay response time. Use the Fast setting unless you experience switching problems when using your amplifier for semi break-in operation.

Note:

The TX/RX control method differs depending on external amplifier models. Some amplifiers enter the TX mode when the control terminal is grounded. For those amplifiers, connect pin 2 of the the connector to the control terminal of the amplifier.

■ Accessory Equipment (ACC 2)

If you intend to use this transceiver for any of the digital modes, connect the input/output connections from a Terminal Node Controller (TNC) for Packet operation, a Multimode Communications Processor (MCP) for operation on Packet, PacTOR, AMTOR, G-TOR, or FAX, or a Clover interface to this connector.

SSTV and phone patch equipment can also be connected to ACC 2. SSTV operation is possible by connecting the input/output from a computer sound card to ACC 2, then running an SSTV application on the computer.

To operate on the digital modes, you will need the following equipment:

•Personal computer with communications software (alternatively, a “dumb” terminal capable of sending ASCII

commands)

• TNC (Terminal Node Controller) or MCP (Multimode Communications Processor)

• TNC or MCP power supply

• RS-232C cable

• 13-pin DIN plug and cable

Connect your TNC or MCP to the ACC 2 connector on the transceiver Rear Panel using a cable equipped with a 13-pin DIN plug.

Do not share a single power supply between the transceiver and the TNC or MCP. Keep as wide a separation between the transceiver and computer as practical to reduce noise-pickup by the transceiver. Refer to the accompanying table for connection information.

• After the “HELLO” message, the frequency and other indicators light. Pressing [ ] (POWER) too long, switches the power OFF. If the TS-870S has not been used for an extended period, “HELLO” may not appear immediately.

To switch OFF the transceiver, press [ ] (POWER).

• After the transceiver has been switched ON, it can then be switched OFF or ON by using only the power switch on the DC power supply.

ADJUSTING VOLUME

Furthermore, using a faster AGC setting {page 44} will help eliminate the blocking affect of the large AGC voltage that is developed due to a strong adjacent station.

Depending on the type and gain of your antenna, and the condition of the band, you may prefer leaving the RF gain control turned counterclockwise by some amount instead of turning it fully clockwise.

ADJUSTING SQUELCH

The purpose of squelch is to silence audio output from the speaker when no signals are present. Setting the squelch threshold too high causes the squelch to remain closed while a weak signal is present. Setting the threshold too low allows noise to be heard between transmissions from other stations. Many operators prefer leaving the squelch control fully counterclockwise unless operating full-carrier modes such as FM or AM.

RADIO FREQUENCY (RF) GAIN

Usually, set the RF gain control maximum clockwise. If you are having trouble hearing the desired signal due to excessive atmospheric noise or interference from other stations, it may help to reduce the RF gain.

To do this, take note of the peak S-meter reading of the desired signal, then turn the RF gain control counterclockwise to match this peak reading with the illuminated S-meter segments. Signals that are weaker than the level set with the RF gain control will be attenuated. Reception of the station is easier.

•Turn the M.CH/VFO.CH control clockwise to increase the frequency; counterclockwise to decrease the frequency.

Due to the large step sizes available, you can quickly move across the band. When the minimum or maximum receive frequency for the transceiver is reached, turning the M.CH/VFO.CH control will not decrease or increase respectively the frequency.

Menu No. 44 (STEP.ADJ) affects how the M.CH/VFO.CH control tunes. When Menu No. 44 is ON (default), rounding occurs on the first step (“click”) of the M.CH/VFO.CH control as shown below:

■ Changing Step Sizes

Select the step size that you prefer for the M.CH/VFO.CH control via Menu No. 43 (CH. STEP). Available step sizes are 1 kHz, 5 kHz and 10 kHz. The default is 10 kHz.

Within the AM broadcast band, the step size automatically defaults to 9 kHz (U.S.A./ Canada versions: 10 kHz) for the AM mode. This step size can be switched between 9 (ON) and 10 kHz (OFF) via Menu No. 42 (BC. STEP). Selecting OFF in Menu No. 42 allows you to use the step size specified via Menu No. 43 (1, 5, or 10 kHz). While in the AM broadcast band, changing the step size via Menu No. 42 will change the selected frequency to the nearest broadcast channel on the next use of the M.CH/VFO.CH control.

If you enjoy listening to international shortwave broadcasters, the M.CH/VFO.CH control is also the best way to manually scan these bands. Select the 5 kHz step size via Menu No. 43 (CH. STEP) since most shortwave broadcasters are spaced 5 kHz apart. Set Menu No. 44 to ON. To listen to a broadcaster on a channel that is not a 5 kHz multiple, use the Tuning control to zero-in to the exact frequency.

Example 1: Menu No. 44 (STEP.ADJ) is ON

• Menu No. 43 (CH. STEP): 10 kHz step size

• Selected frequency: 14.261.73 MHz

Turning the M.CH/VFO.CH control clockwise one step changes the frequency to 14.270.00 MHz, and one more step changes the frequency to 14.280.00 MHz. The rounding occurred on the first step.

Similarly, with 14.261.73 MHz selected, turning this control counterclockwise one step changes the frequency to 14.260.00 MHz, and one more step changes the frequency to 14.250.00 MHz. Again, the rounding took place on the first step.

Example 2: Menu No. 44 (STEP.ADJ) is OFF

• Menu No. 43 (CH. STEP): 10 kHz step size

• Selected frequency: 14.261.73 MHz

Turning the M.CH/VFO.CH control clockwise one step changes the frequency to 14.271.73 MHz, and one more step changes the frequency to 14.281.73 MHz. No rounding occurs.

With 14.261.73 MHz selected, turning this control counterclockwise one step changes the frequency to

14.251.73 MHz, and one more step changes the

frequency to 14.241.73 MHz. Again, no rounding occurs.

FINE TUNING

For SSB, CW, and FSK modes, the Tuning control normally tunes through 10 kHz per revolution of the control. For FM and AM modes, one revolution of the Tuning control changes the frequency by 100 kHz. These tuning rates can be halved via Menu No. 41 (F.STEP).

In addition, the Fine Tuning function reduces the step size of the Tuning control further which allows you to tune more slowly and precisely.

DIRECT FREQUENCY ENTRY

Entering a frequency directly from the numeric keypad can be the fastest method to change to a specific frequency that is far removed from your current frequency.

The following points will help you enter a frequency correctly:

•Only the digits 0, 1, 2, or 3 can be entered for the

10 MHz digit (first digit). Pressing any digit 4 ~ 9 will cause the digit to be entered in the 1 MHz position. Therefore, to select a frequency of 3 MHz or lower, enter 0 for the 10 MHz digit.

• When the 10 Hz digit (last digit) is entered, the digit 0

is entered automatically for the 1 Hz digit, and frequency entry is completed. The 1 Hz digit is not displayed.

• If [ENTER] is pressed after beginning to enter digits,

0 is entered automatically for the remaining un-entered digits, and frequency entry is completed.

• Attempting to enter a frequency that is outside the

TS-870S frequency range causes an alarm to be generated. The entered frequency is rejected.

• If an incorrect digit is pressed, restore the previous

frequency by pressing [CLEAR], or [SEND], or Mic [PTT].

• When an entered frequency is accepted, RIT

{page 44} and XIT {page 45} are switched OFF, but the RIT or XIT frequency is not changed.

It’s wise, and required by law, to select the lowest transmit power that allows reliable communication. Reducing power lowers the risk of interfering with others on the band. On the TS-870S, it is possible to change output power while transmitting.

To change your output power, turn the PWR control counterclockwise to reduce power and clockwise to increase power. The PWR scale on the Front Panel meter provides an indication of your output power in watts while you are transmitting.

TRANSMIT CARRIER LEVEL

The CAR control must be used for adjusting the carrier level for CW, AM, and FSK modes. The control also adjusts the Speech Processor output level when this function is used in the SSB mode. In general, set the CAR control so that the ALC meter reads within the limits of the ALC zone. If the carrier level is set via the computer interface, the position of the CAR control on the Front Panel is ignored. After turning the CAR control, the control becomes active again.

MICROPHONE GAIN

The MIC gain control must be adjusted any time the SSB (LSB or USB) or AM mode is used without speech processing. Set the MIC gain control so that the ALC meter reads within the limits of the ALC zone at all times. When Speech Processing is used, the microphone gain is fixed as shown in the table below regardless of the MIC gain control setting.

MENU SETUP

WHAT IS A MENU?

Many functions on this transceiver are selected or configured via a software-controlled Menu instead of physical controls on the transceiver. Once familiar with the Menu system, you will appreciate the versatility it offers. No longer is the number and complexity of features restricted by the physical controls and switches on the Front Panel.

MENU ACCESS

The following procedure explains how to check or change any of the Menu items.

1 Press [MENU].

2 Turn the M.CH/VFO.CH control to select the desired

Menu No.

3 Press [UP], or [DOWN], or Mic [UP], or Mic [DWN]

to change the current selection for this Menu item.

4 Press [MENU] or [CLR] to exit Menu mode.

• If the power is switched OFF before this step is completed, the selection just made will be canceled.

MENU A/ MENU B

■ Programming the Quick Menu

1 Press [MENU].

2 Turn the M.CH/VFO.CH control to select the

desired Menu No.

3 To add the selected Menu item to the Quick

Menu, press [M.IN].

• The star lights indicating that the item has been added to the Quick Menu.

AGC AUTO MENU

• Each press of [M.IN] toggles the item into or out of the Quick Menu.

4 Press [MENU] or [CLR] to exit Menu mode.

■ Using the Quick Menu

1 Press [MENU].

2 Press [1MHz].

•“MHz” lights.

The TS-870S has two menus. These menus are called Menu A and Menu B. The menus contain identical functions; however, each menu can be configured independently.

For example, you may enjoy two different kinds of operating activities but you like to configure the transceiver differently for each activity. Menu A could be configured with one set of transmit signal characteristics, DSP settings, programmable buttons, frequency steps, etc. Menu B could be configured completely differently. By switching from Menu A to Menu B, you could instantly change Menu configuration and button assignment to suit your current operating style. Or, two operators may share a single transceiver. By dedicating one Menu per operator, each would always enjoy the best configuration.

With a little thought, you can determine the best setups for each Menu for your personal situation. Once you’ve decided your strategy, select via Menu No. 00 (MENU.A/B) the Menu that you want to set up first. Then use the information in this chapter and on the referenced pages to configure your ultimate operating environments.

QUICK MENU FUNCTION

The Quick Menu function complements the Menu A/B selection capability by allowing you to create your own customized but abbreviated Menu. Copying Menu items to the Quick Menu has no effect on the Menu. You should add only those Menu items to the Quick Menu that you use frequently.

AGC AUTO MENU

3 Turn the M.CH/VFO.CH control to select the

desired Quick Menu No.

• If the Quick Menu has not been programmed yet (see previous section), then turning the M.CH/VFO.CH control causes an alarm to be emitted (either “CHECK” in Morse code or a triple beep).

4 Press [UP], or [DOWN], or Mic [UP], or

Mic [DWN] to change the current selection for this Quick Menu item.

5 Press [MENU] or [CLR] to exit Quick Menu

mode.

TEMPORARY MENU RESETTING

This convenient function allows you to temporarily reset all Menu items to their factory default selections. This can be useful to verify whether a Menu setting is causing undesirable operation.

1 Press [CLR]+[ ] to temporarily reset all Menu items

to factory default values.

• The “MENU” indicator flashes.

2 To change all Menu items back to your own

programmed values, switch OFF the transceiver, then switch it back ON.

COMMUNICATING

SSB TRANSMISSION

SSB is now the most commonly-used mode on the HF Amateur bands. This popularity is not surprising due to its narrow bandwidth requirements and its good long distance communications capability that demands minimum transmit power when compared with other voice modes. These reasons, combined with the fact that modern Amateur transceivers deliver reasonably good audio quality, make SSB the mode that most prefer on HF. Due to this popularity, you will want to use the technology available on the TS-870S as explained in this and later sections to make your transmitted signal the best possible.

Refer, if necessary, to “OPERATING BASICS” beginning on page 19 for complete receiving details for any mode.

1 Select the operating frequency.

2 Press [LSB/USB] to select either upper or lower

sideband mode.

AGC AUTO

USB

SLOW SCAN TV/ FACSIMILE

SSTV complements SSB operating since a voice contact is established first before pictures are exchanged. Though once a specialty mode involving a very small percentage of Amateurs, slow scan television is now increasing in popularity as a result of the capability of computers.

No longer is it necessary to squint at an old CRT to view a continuously fading image. It isn’t necessary to invest in a large amount of additional equipment anymore either. SSTV can be a convenient method of adding interest to otherwise routine voice contacts. Instead of trying to describe your station, just show it. Many Amateurs are only lacking a little application software that uses your computer sound card for transmitting and receiving monochrome or full-color SSTV images.

4 Press and hold down the Microphone [PTT] switch,

or press [SEND].

• The “ON AIR” indicator lights.

• Refer to “VOX” {page 45} for information on automatic TX/RX switching.

5 Speak into the microphone and adjust the MIC gain

control so that the meter reads in the ALC zone but doesn’t exceed the upper ALC zone limit.

• Speak in a normal tone and level of voice. Speaking too close to the microphone, or too loudly, may increase distortion and reduce intelligibility.

• The ALC level is more restricted than previous KENWOOD transceivers due to the added benefit of the DSP-controlled Microphone AGC function {page 47}.

•With the Speech Processor switched OFF, the

CAR control has no function in this mode.

6 If you want to use speech processing, press [PROC]

to switch on the Speech Processor and adjust as described on page 46.

7 Release the Microphone [PTT] switch, or press

[SEND] again, to return to the receive mode.

• The “ON AIR” indicator goes out.

The high resolution that is possible using facsimile (FAX) can allow you to exchange more detailed graphics than SSTV allows. Due to the longer transmission times required for FAX, it’s best to use this mode when band conditions are stable with strong signals.

Popular FAX frequencies include the following:

• 7245, 14245, 21345 (Intern. Net), 28945 kHz

Operation on SSTV or FAX mainly involves learning the functionality of your computer application or accessory hardware that supports these modes. Consult the documentation that comes with your software or accessory equipment.

Note:

When operating either SSTV or FAX, use a fast AGC setting

and switch OFF your Speech Processor for best results.

This completes the “SSB TRANSMISSION” section. Refer to “OPERATING AIDS” beginning on page 44 for information about additional useful functions for operating.

6 COMMUNICATING

CW TRANSMISSION

CW operators know that this mode is a reliable method of communicating under the worst conditions. Although it’s true that newer digital modes rival CW as being equally as useful in poor conditions, these modes do not have the long history of service yet nor the simplicity that CW can have. Therefore, functions required by CW operators were given serious consideration from the start of the TS-870S design.

Refer, if necessary, to “OPERATING BASICS” beginning on page 19 for complete receiving details for any mode.

control.

Refer to “IF SHIFT” {page 51}.

ZERO-BEATING

Zero-beating means matching your transmit frequency with the station that you are receiving. This is important if you expect other stations to hear you without them retuning their receivers. Zero-beating also saves space on the band since only a single frequency is used by you and the other station for your contact. If you are part of a “roundtable” where more than two stations are participating but each is on a different frequency, it’s frustrating to keep retuning to a different frequency each time one of the roundtable stations begins sending. Learn to zero-beat accurately and quickly.

1 Press [VOX] and press [RIT] to switch OFF the VOX

and RIT functions respectively.

• “VOX” and “RIT” go out.

2 With CW mode selected, turn the Tuning control to

tune in a CW station for maximum signal strength.

3 Close your key to activate the sidetone.

•You will hear a steady tone.

TX SIDETONE/ RX PITCH FREQUENCY

The transmit sidetone is the monitor tone you hear from your transceiver as you send CW. It is necessary so you can hear what you are transmitting. It is also useful for checking that your key contacts are closing, the keyer is functioning, or for sending practice without putting a signal on the air. The volume of the sidetone is adjusted by the MONI control.

Receive pitch refers to the frequency of the CW note that you hear after tuning your receiver for maximum receive signal strength. On the TS-870S, the frequency of the sidetone and receive pitch are equal and selectable. You can select the frequency that is most comfortable for you via Menu No. 24 (PITCH). The default is 800 Hz.

2 Press [SEND].

• The receive audio is muted.

• Holding down Microphone [PTT] also switches between receive and transmit.

3 Send CW.

■ Setting Delay Time

The delay time is the length of time that the transceiver remains in transmit mode after the key is opened. This time should be set based on your keying speed and your personal preference.

While sending using Semi Break-in, adjust the DELAY control for the delay you prefer. The control has a range from 50 ms ~ 800 ms in steps of 50 ms.

FULL BREAK-IN

Full Break-in returns the transceiver to the receive mode as soon as the key contacts open. It’s possible to hear if another station wants to interrupt, and it also allows you to hear interference that may begin after you start sending.

CW REVERSE (RECEIVE)

This function switches receive from the default upper sideband to the lower sideband, therefore, interference that is heard may be eliminated. When your receive frequency is identical to the transmit frequency of the other station, the CW Reverse function has no effect on receive tone or your transmit frequency.

RISE/DECAY TIMES

The rise time of a CW signal is the time for the RF output to rise to its maximum power after the key is closed. This time excludes the make delay that occurs after closing the key but before the RF output actually begins to increase. You can adjust the CW rise time for the TS-870S via Menu No. 23 (CW RISE). The default is 4 ms. This adjustment also affects the decay time. The decay time excludes the short break delay from the moment when the key opens to when the RF output begins to fall.

The default setting is fine for low to moderate keying speeds and normal weighting (dot/dash ratios). The 2 ms setting is good for higher CW speeds or when operating with unusual dot/dash ratios. The available rise time selections include 2, 4, 6, and 8 ms.

ELECTRONIC KEYER

The keyer supplied with the TS-870S is a full-featured K-1 Logikey keyer that will delight anybody that respects a good keyer. A great deal of information on using this keyer is provided in this manual, not because it is difficult to use, but because it has an incredible number of features. Some of the features of your keyer include:

• Iambic operation with dot and dash memories

•Programmable via commands sent from your key

• Emulation modes for other keyer types — you won’t have to re-train yourself if you’re used to a keyer with different timing

• Soft-sectored messages that can “call” each other and can contain embedded functions

• Automatic contest serial number generation

•Digital and linear speed control (6 ~ 60 wpm)

• Adjustable weight for code elements (25% ~ 75%)

•Tune function for continuous key down

• Selectable automatic character spacing

• Message loop capability for continuous replay

It is probably best to learn the keyer’s basic functions first, then use it on-the-air. Over time, you will build up your knowledge of its operation bit by bit. Don’t try to memorize everything at one time!

Points to know before beginning:

• Although the sidetone can be heard while using any mode, CW mode must be selected to set functions on the keyer.

• When pressing two or more keys on the keypad to select a keyer function, press the correct keys as instructed, then release them. You know you’ve held them down too long if you hear a continuous tone before releasing the keys. In this case, a rapid multi-dit error alarm sounds when you release the keys to confirm the error.

■ Storing CW Messages

The two modes available for storing messages are Character mode and Real Time mode. Each message may be as long as you want provided that the total of all four messages including spaces does not exceed about 220 characters. You must use the internal keyer to use the message storage function. If you happen to turn OFF the power while storing a message, the last letters input may be deleted. You cannot store messages if you are operating split mode (transmit mode different than receive mode).

Using Character mode (default):

This mode uses message memory most efficiently. Each Morse character uses one byte of memory. When you play back your recorded messages, they will be sent with precise intercharacter and interword spacing.

1 Press [CH 1] or [CH 2] or [CH 3] or [CH 4] for

approximately two seconds until you hear a tone.

• The keyer will send the letter “C”. This stands for Character mode.

• If the keyer sends “R” (for Real Time), you must switch to Character mode by using the Function mode {page 36}.

2 Send the first word of your message then pause.

• The keyer will send the letter “I” indicating it has accepted your word.

3 Repeat Step 2 pausing to hear the “I” before

sending the next word until all words of your message are entered.

• If you make a sending mistake, send seven or more dits to signal an error, then wait for the keyer to respond with the last correct word. You can then send the next word that you want in the message. Each time that you send the 7-dit error signal, you erase one more word.

4 Press the same button as pressed in Step 1.

Using Real Time mode:

Real Time mode captures exactly what you send without altering your spacing. This mode cannot use Embedded Functions {page 37}. Also, you cannot correct words by using the 7-dit error signal as in Character mode.

Before beginning, switch to Real Time mode by using the Function mode {page 36}.

1 Press [CH 1] or [CH 2] or [CH 3] or [CH 4] for

approximately two seconds until you hear a tone.

• The keyer will send the letter “R”. This stands for Real Time mode.

2 Send your entire message.

3 Press the same button as pressed in Step 1.

•Message recording begins at the moment the first character is sent, and continues until this step is completed. Any pause between the last character and this step is recorded as part of the message.

■ CW Message Playback

Messages may be transmitted using the VOX function or manual TX/RX switching. The procedure below uses the VOX function. Simply tap the paddle at any time to stop a message while it is playing back, or press any two of [CH 1], [CH 2], [CH 3], or [CH 4] to stop the message without transmitting an extra character. Resuming playback after such an interruption replays the message from the beginning.

Switching OFF the power while playing back a message could delete the message. You cannot play back messages if you are operating split mode (transmit mode different than receive mode).

To check a message without transmitting:

1 Press [VOX] to switch OFF the VOX function.

2 Press the memory channel button ([CH 1] or

[CH 2] or [CH 3] or [CH 4]) that contains the

message that you want to check.

• The message plays.

•To play back up to 8 messages, press the

corresponding memory channel buttons in sequence during playback.

To transmit a message:

1 Press [VOX] to switch ON the VOX function.

2 Press the memory channel button ([CH 1] or

[CH 2] or [CH 3] or [CH 4]) that contains the

message that you want to transmit.

•The message is transmitted.

•To transmit up to 8 messages, press the

corresponding memory channel buttons in sequence during playback.

The “Q” Function command {page 36} allows you to queue several messages to form a longer message.

Example:

•“Q” Function status: ON

• Channel 1 contents: “CQ”

• Channel 2 contents: “de DFØTK”

In this example, pressing the button sequence [CH 1], [CH 1], [CH 1], [CH 2] would send “CQ CQ CQ de DFØTK”.

■ Erasing CW Messages

1 To erase a memory channel’s message, press its

associated button ([CH 1] or [CH 2] or [CH 3] or [CH 4]) until you hear a tone.

• The keyer will send the letter “C” or “R” depending whether you are in Character or Real Time mode.

2 Press the same memory channel button again.

• The message in that memory is now erased.

■ Inquiry Functions

Inquiry functions report the current state of the keyer. Information is played to the operator in Morse code with the monitor automatically enabled and keying output disabled.

Description

Toggles the automatic character spacing feature ON or OFF. The keyer confirms the new state by sending "ON" or "OFF". Auto-spacing helps form properly spaced characters within a word. Character crowding is prevented by forcing at least 3 space elements whenever more than one space is detected. This effect is especially noticeable at low speeds. Without auto-spacing, character spaces are determined by the operator.

Decrements the serial number by 1, effectively canceling the automatic increment applied when last played from a message. The decrement function accommodates re-sending the last serial number, as might be needed when a repeat of a contest exchange is requested.

Sets the speed used for function entry to dd wpm, where dd are two digits in the range 06 ~ 30. This speed is used to enter commands and load messages. It is independent of operating speed and is unaffected by the analog speed control. Alternatively, "dd=00" makes the function speed track the operating speed.

Causes the keyer to enter the Hand-key mode. Keying output will follow closures of the dot and dash paddle levers, allowing hand-sent code. Normal iambic keyer operation is regained by any button closures.

Increases keying on-time and decreases keying off-time by dd milliseconds, where dd are two digits in the range 00 ~ 25. Although similar to increasing weight, this adjustment is independent of speed. This setting is used primarily to correct keying distortion introduced by the transceiver using Break-in operation.

Toggles the load mode between Character and Real Time. The keyer confirms the new mode by sending "C" or "R" as appropriate.

Initializes the contest serial number to dddd, where dddd are four digits in the range 0000 ~ 9999. Four digits must be entered (with leading zeros if needed).

Toggles the input queue ON or OFF. The keyer confirms the new mode by sending "ON" or "OFF" as appropriate. When OFF, message button activations are acted upon immediately, canceling any message in progress. When ON, up to eight button presses are remembered in order and acted upon in succession as each message completes.

Reverses the dot and dash paddles as may be desired for left-handed operators. Sets the current operating speed to dd wpm, where dd are two digits in the range

06 ~ 60. The speed function establishes the current knob position at the entered speed. The knob can then be employed to vary the speed faster or slower over a total range of 3:1. Control via the knob is linear and increases speed clockwise.

Increases the operating speed by d wpm. d is a single digit in the range 0 ~ 9. Decreases the operating speed by d wpm. d is a single digit in the range 0 ~ 9. Allows an operator to select emulation of the timing characteristics of other keyers. Sets code weight to dd percent, where dd are two digits in the range 25 ~ 75.

Weight is the duty cycle of a continuous string of dots, which is 50% for perfect code. A higher weight produces a heavier sound, and a lower weight causes characters to sound lighter. Once set, weight remains constant and independent of speed.

Continuously keys the output for purposes of transmitter and amplifier adjustment. Tuning is stopped by simply tapping either the dot or dash paddle.

Controls the way that zeros and nines are sent in the serial number. See "Serial Number Options".

■ Embedded Functions

Certain functions can be embedded within character messages. The command strings are prefixed by a “/”, and are entered as a separate word. The letters following a “/” that are contained within a word are not interpreted as an embedded function. For example, the keyer understands that “WD6DJY/VE7” does not include an embedded command since “/VE7” is not sent as a separate word. These commands must be stored in CH 1 ~ CH 4; they cannot be manually sent.

A speed-independent pause of d.d seconds is inserted, where dd are two digits in the range 00 ~ 99. For example, /P35 will result in a delay of 3.5 seconds. Pauses longer than 9.9 seconds are obtained by using consecutive commands that total the value desired.

Stops playback to allow handsent entry. When manual keying is completed, press the button for the message being played and the message will resume transmitting. Multiple "/R" commands are permitted.

FM TRANSMISSION

FM operation on HF frequencies solves the problem of how to have long distance voice communication with the finest audio quality. When combined with the full-quieting aspect of FM signals that suppress background noise on the frequency, FM can be the best method for maintaining regular schedules with friends. And when conditions are unusually good allowing simplex FM contacts over intercontinental paths, you may feel as though you are using your local VHF repeater to talk across town instead of using the HF spectrum for multi-hop communication.

Refer, if necessary, to “OPERATING BASICS” beginning on page 19 for complete receiving details for any mode.

FM REPEATER OPERATION

Compared to the usual simplex method of FM communications on HF, which is radio to radio with antennas at or slightly above average terrain, you can often transmit much farther through repeaters.

Repeaters are typically located on a mountain top or other elevated location. Most often they operate at a higher ERP (Effective Radiated Power) than the average mobile or fixed amateur station. This combination of elevation and high ERP allows communications over wider and longer distances than can be achieved by the average station.

HF repeaters operate only in the 29 MHz FM sub-band. This special service combines the advantages of FM operation, good fidelity with noise and interference immunity, with the excitement of HF DX (long distance) communications. Even on a quiet day, 10 meter FM provides reliable around-town communications with the potential for sudden DX from across the country or around the world.

Note:

◆

When operating through a repeater, over deviation caused by speaking too loudly into the microphone can cause your signal to “talk-off” (break up) through the repeater.

◆

When Subtones can be transmitted, “TONE” lights on the Display.

◆

Memory Transfer does not copy the stored Subtone frequency data to the VFO.

◆

The Subtone transmitted is the tone associated with the memory channel or the VFO frequency that is used for the transmit function. When you transmit using a VFO frequency or the channel 99 frequency, the Subtone selected via Menu No. 57 (SUB.TONE) and Menu No. 58 (SUB.TONE) will be used; however, when transmitting using a memory channel, the Subtone stored in that channel will be transmitted.

■ Selecting Subtone Frequency

Some 10-meter FM repeaters use CTCSS (Continuous Tone Coded Squelch System) to prevent other repeaters on the same frequency from keying thus locking each other up. This repeater access system is also referred to as Tone or PL (“Private Line”). If CTCSS is used by a repeater in your area, set the Subtone frequency. The default is

88.5 Hz.

DIGITAL OPERATION

Since Multimode Communications Processors (MCP) have become popular, many Amateurs enjoy operating using a number of digital modes. The power and variety of Amateur radio increased greatly with the development of MCP that can use your TS-870S transceiver as the communications link.

For example, it’s possible to take advantage of the camaraderie found on RTTY, then move to Packet to access an RBBS (Radio Bulletin Board System) to download a recent shareware program you’ve heard about, and then move again to AMTOR or PacTOR to deposit mail in a regional mailbox for forwarding. After that, you may switch to G-TORTM or Clover for a lightning fast file transfer with a friend.

Consult ACCESSORY CONNECTIONS {pages 5~7} before proceeding if you need installation information. It is assumed here that you have all hardware, and software if necessary, already correctly installed.

RTTY (FREQUENCY SHIFT KEYING)

Important Menu items to be aware of before beginning to operate RTTY include the following:

•Menu No. 62 (FSK.SHFT): Selects 170, 200, 425, or 850 Hz shift. The 170 Hz shift default is used on the Amateur bands.

• Menu No. 63 (MARK.POL): Allows reversal of the key-down polarity between mark and space. The default is space (OFF).

• Menu No. 64 (FSK.TONE): Switches between a high tone (2125 Hz) and a low tone (1275 Hz). The default is 2125 Hz. The high tone is commonly used nowadays.

6 COMMUNICATING

On most HF bands, audio frequency shift keying (AFSK) is used. This method of modulation uses audio tones therefore either the LSB or USB mode should be selected. Traditionally, LSB is used similar to RTTY with the exception of AMTOR which is normally operated using USB.

In some countries, the licensing authorities permit F2 operation on some frequencies in the 10 meter band. For this type of operation, select the FM mode.

Note:

When using the SSB mode for digital operation, use a fast AGC setting and switch OFF your Speech Processor. Also, take advantage of the different filter bandwidths available via Menu No. 19 (PKT.FIL). Remember to set Menu No. 19 to OFF for voice operation since the filters available are too narrow for voice.

This completes the “DIGITAL OPERATION” section. Refer to “OPERATING AIDS” beginning on page 44 for information about additional useful functions for operating.

SPLIT-FREQUENCY OPERATION

Split-frequency operation uses one VFO for the receive frequency and the other VFO for the transmit frequency. While operating “split”, the VFOs switch automatically when you switch from receive to transmit and vice versa. This allows you to move either VFO frequency independently without affecting the other.

When a rare or desirable station is heard, he or she may immediately get many responses, all at the same time. It quickly becomes difficult to separate and identify both the original calling station (usually a DX station), and the many responding stations. This “DX pileup” is exciting, but it is also very inefficient and frustrating. Often the DX station is lost under the noise and confusion of many calling stations.

If things grow out of hand, it is the DX station’s responsibility to take control by announcing that he will be “listening up 5 (kHz, from his present transmit frequency)”, or “listening down between 5 and 10 (kHz)”. This usually means the DX station will not change his transmit frequency, but will begin split operation in order to tune among the calling stations, pick out a call sign or two, and begin working those stations. Since, for the moment, the DX station is holding his transmit frequency, you should not change your receive frequency.

If you find that you are suddenly being called as that rare or desirable station, your ability to control the situation and complete contacts is much improved by “going to split”. The following procedure explains how to operate split frequency on the TS-870S.

1 Press [RX A] or [RX B] or [RX M.CH].

•Your receive frequency will be the current frequency selected by VFO A, by VFO B, or by the current memory channel respectively.

• If you press [RX M.CH], then that memory channel must contain a split channel unless you select a VFO for the transmit frequency in the next step. See “MEMORY CHANNEL STORAGE, Split-frequency Channels” {page 55}.

2 Press [TX A] or [TX B] or [TX M.CH].

•Your transmit frequency will be the current frequency selected by VFO A, by VFO B, or by the current memory channel respectively.

• If you pressed either [RX A] or [RX B] in Step 1, then you must select the other VFO in this step, or press [TX M.CH].

Successfully contacting a DX station in a pileup often depends on making a well-timed call on a clear frequency. The best way to know if your intended transmit frequency is clear is to use [TF-SET]. Press [TF-SET] and listen. Had you transmitted at that moment, would you have transmitted simultaneously with other stations or the station that you are calling? After using [TF-SET] a couple of times in this manner, you will learn the rhythm of the DX station and the pileup. Use the information to select a relatively clear transmit frequency and to transmit at the exact instant when the DX station is listening but the majority of the group aren’t transmitting.

SATELLITE OPERATION

Though not as common as VHF/UHF satellite operation, HF satellite operation is possible depending on which satellites are currently in orbit around the Earth. When HF propagation is poor, satellite operation can provide an incentive to get back on the air. Since this communications mode is so reliable, you may discover you actually prefer satellite operation over the hunt-and-miss method of communicating via the ionosphere.

An example of a Mode K satellite that has uplink and downlink frequencies that are both on HF is the Radio Sputnik 12 (RS-12). Launched in the early 1990s, this satellite is in a low Earth orbit and provides brief windows of opportunity for use as it passes quickly over your location. This satellite accepts SSB or CW signals on the 15 meter band and outputs them on 10 meters.

AGC AUTO SPLIT

USB

Contacts are possible on bands that might otherwise be vacant during low periods of the solar cycle. Your TS-870S can also be used with Mode A satellites, those that use a VHF uplink and an HF downlink, if you also have an SSB/CW VHF transceiver.

If you’re interested in pursuing Mode K operation, contact AMSAT (Radio Amateur Satellite Corporation). This group of satellite operators, located all over the world, support the construction and operation of satellites.

RIT (RECEIVE INCREMENTAL TUNING)

RIT provides the ability to change your receive frequency by ±9.99 kHz in steps of 10 Hz without changing your transmit frequency. If the Fine Tuning ([FINE]) function is ON, the step size is 1 Hz. RIT works equally well with all modulation modes and while using VFO mode or Memory Recall mode.

It’s a good habit to switch OFF the RIT function after a contact is finished. This returns the receive frequency to the transmit frequency. It ensures that you don’t listen by mistake on a different frequency from your transmit frequency on the next contact. When using Memory Recall mode, RIT only functions with a memory channel containing stored data. Since an empty channel contains no receive frequency, RIT cannot function.

VOX (VOICE-OPERATED TRANSMIT)

VOX eliminates the necessity of manually switching to the transmit mode each time that you want to transmit. The transceiver automatically switches to transmit when the VOX circuitry senses that you have begun speaking into the microphone.

When using VOX, get into the habit of pausing between thoughts to let the transceiver drop back to receive briefly. You will then hear if anybody wants to interrupt, plus you will have a short period to gather your thoughts before speaking again. Your listener will appreciate your consideration as well as respect your more articulate conversation.

• TX Inhibit ON: Transmissions are not possible.

Switch the function ON or OFF via Menu No. 27 (TX INH). The default is OFF.

■ Microphone Input Level Adjustment

To enjoy the VOX mode, take time to set the gain of the VOX circuit to the correct level.

2 Access Menu No. 28 (VOX.GAIN), then select

different settings (default is 4) until the transceiver reliably switches to transmit each time you speak.

• The best setting will allow the transceiver to switch between receive and transmit; however, background noises near your operating position should not falsely switch the transceiver.

CUSTOMIZING TRANSMIT SIGNAL CHARACTERISTICS (SSB/AM)

The quality of your transmitted signal is important regardless which on-the-air activity you pursue. However, it’s easy to be casual and overlook this fact since you don’t listen to your own signal. The following sub-sections provide information that will help you tailor your transmitted signal.

■ Changing Transmit Bandwidth

Transmit bandwidth is modified via Menu No. 29 (TX.WIDTH). The available selections include:

• 1800, 2000, 2300, 2600, and 3000 Hz

The default is 2300 Hz. Consult the Bandwidth/ Bandshift Table for additional data. When the Speech Processor is switched ON, the bandwidth changes as shown in this table; however, displayed values do not change.

■ Transmit Bandshift

Transmit bandshift is modified via Menu No. 30 (TX.SHIFT). The available selections include:

• 0, 100, 200, 300, 400, and 500 Hz

The default is 300 Hz. Consult the Bandwidth/ Bandshift Table for additional data. When the Speech Processor is switched ON, the bandwidth changes as shown in this table; however, displayed values do not change.

■ Equalizing Transmit Audio

Press [TX EQ.] to toggle the transmit equalizer ON or OFF. To change transmit frequency characteristics, access Menu No. 31 (TX EQ.). The available selections include:

• High boost (H)

• Comb filter (C)

7 OPERATING AIDS

AUTOMATIC MODE

Automatic Mode automatically selects the operating mode according to a set of frequency and mode data that you input. The purpose of Automatic Mode is for the transceiver to select the correct mode for you as you tune within a band. For Automatic Mode to work, you must first program the frequency/mode relationships that you want.

AUTOMATIC MODE BOUNDARIES

• The defaults for all boundaries are 30 MHz USB.

• Boundaries may only be changed (not deleted).

• The mode assigned to a boundary will be selected

while operating on all frequencies below that boundary down to and including the next lower boundary.

• Each boundary is numbered. As the boundary numbers get larger, so must the boundary frequencies.

Example: If Boundary No. 09 is 14.100 MHz, then Boundary No. 10 must be a frequency larger by at least 10 kHz than 14.100 MHz. The lowest frequency that could be stored in Boundary No. 10 is

14.110 MHz. A lower frequency will not be accepted.

• Frequencies larger than the maximum receive frequency cannot be stored.

• There is a maximum of 19 boundary frequencies.

• Automatic Mode is always “OFF” in the range from

the highest boundary to the maximum transceiver frequency.

Example: If 18 MHz CW is stored in Boundary No. 14, tuning to 18 MHz or higher selects USB since the boundary default of 30 MHz USB is stored in Boundary No. 15. Whereas, if 18 MHz CW is stored in Boundary No. 18 (highest boundary), tuning to a frequency lower than 18 MHz selects CW but tuning to 18 MHz or higher will not change the mode (still CW).

Use the following procedure to change a boundary.

1 Press [MENU]+[ ].

• Boundary No. 00 appears.

CWAUTO

2 Turn the M.CH/VFO.CH control to select the

boundary that you want to change.

3 Press [ENTER], then enter the frequency via the

keypad. Alternatively, you can enter the frequencies by using the Tuning control or Mic [UP]/[DWN]. Pressing [UP] or [DOWN] on the Front Panel changes the frequency in 1 MHz steps.

•“– –.– – 0.00” appears if [ENTER] is pressed.

USBAUTO

• The 10 kHz digit is the least significant that can be entered therefore boundaries must be multiples of 10 kHz.

• Four digits must be entered. However, if [ENTER] is pressed after beginning to enter digits, 0 is entered automatically for the remaining un-entered digits, and frequency entry is completed.

• If you enter a wrong digit, press [CLEAR], [ENTER] then re-enter the entire frequency.

4 Press [LSB/USB] or [CW/–R] or [FSK/–R] or

[FM/AM] to select the mode for this boundary.

5 Repeat Steps 2 ~ 4 for each boundary that you want

to change.

6 Press [CLR] to exit from this mode.

• Switching the power OFF before pressing [CLR] results in loss of the entered data.

USING AUTOMATIC MODE

Toggle Automatic Mode ON or OFF via Menu No. 34 (AUT.MODE). The default is OFF. When Automatic Mode is ON, you can always change the mode manually by pressing a Front Panel MODE button. An Automatic Mode boundary must be crossed for the mode to automatically change.

Automatic Mode does not work if you change bands by pressing [UP] or [DOWN]. Instead, the mode last used on the newly selected band will be recalled from the band memory. Switching ON the 1MHz Step function will allow Automatic Mode to work when using [UP] or [DOWN].

In SSB mode when Automatic Mode is OFF, the transceiver automatically selects LSB for frequencies lower than 9.5 MHz, and selects USB for 9.5 MHz or higher frequencies if the Tuning control or Mic

[UP]/[DWN] is used to cross the frequency of 9.5 MHz. This is also true if using the Front Panel [UP] or [DOWN] button. In all modes, the RIT or XIT frequency shift is not taken into account by Automatic Mode. Also, Automatic Mode will not function if a frequency is entered via the keypad on the Front Panel.

AUTOMATIC ANTENNA TUNER

You have the choice of using the internal tuner, an external AT-300 tuner, or both.

Note:

◆

The antenna tuners will not tune outside the authorized transmit limits of Amateur bands.

◆

If an external AT-300 tuner is connected, the internal tuner is bypassed when the ANT 1 connector is selected. The AT-300 cannot be used with the ANT 2 connector.

◆

When tuning in CW mode, the SWR meter may deflect upscale momentarily. This is not a fault.

◆

If using Full Break-in CW, the internal antenna tuner can be bypassed completely or can be in-line for both transmitting and receiving. Even when OFF is selected via Menu No. 08 (RX AT), received signals pass through the antenna tuner. To protect the antenna tuner relay, the tuner cannot be used only for transmitting.

PRESETTING (INTERNAL TUNER ONLY)

After each successful tuning session, the Preset function stores the data for the position of the tuning capacitors on each band. Then, if the frequency is changed while the internal tuner is switched ON, this function automatically positions the capacitors without need for retuning. After changing bands, the Preset function activates for the newly selected band.

A different set of data is stored for each of the 18 antenna tuner bands (see table) and for each antenna connector (ANT 1 and ANT 2). Therefore, enabling the other antenna connector by pressing the [ANT] button may also cause the Preset function to activate. If no Preset data exists for a particular band/ antenna combination, then the default data for 50 Ω is stored.

Presetting does not activate while transmitting. For split-band operation, even if Menu No. 08 (RX AT) is ON, the antenna tuner is bypassed while receiving. Also, at all times, presetting is only done for transmit frequencies.

PRESET BANDS FOR INTERNAL TUNER

Note:

The lower limit is inside the band in each case; the higher limit is inside the next higher band. For example, 14.1 MHz is in Band 12 whereas 14.49 MHz is in Band 13 (exception: 30 MHz is in Band 18).

• If the tuner has not adjusted itself yet for the selected frequency, then AT TUNE lights, and Preset tuning begins. Signals pass through the antenna tuner during this time. If Menu No. 08 (RX AT) is OFF, the antenna tuner is bypassed. The AT TUNE light goes out when presetting is completed. You cannot transmit while presetting is in progress.

AT TUNE

• If Preset data exists, the next step cannot be done until the transceiver completes the Preset tuning.

2 Press [AT TUNE].

• To cancel tuning for any reason, press [THRU/AUTO] or [AT TUNE].

• If the Preset tuning is aborted by pressing [AT TUNE], the new temporary data will be used, but this new data does not update the stored Preset data. Also, the new temporary data will be lost if the operating band is changed. Return to the stored Preset data by pressing [THRU/AUTO] OFF and then ON again.

• AT TUNE lights and stays lit while the tuner tunes. When the light goes out, the tuner has successfully matched the transceiver to the antenna system with an SWR less than the value set in Menu No. 33 (TUN.WIDE). You can begin operating.

• If tuning doesn’t finish within about 20 sec, an alarm sounds. You may stop the alarm and the tuning by pressing [AT TUNE]. The alarm can be either a triple beep or the Morse code “CHECK” depending on the Menu No. 37 (WARN. BP) setting.

• After each successful tuning, the Preset data is updated.

Note:

◆

While receiving with Menu No. 08 (RX AT) ON on frequencies outside the Amateur bands, sensitivity is lowered.

◆

It’s a good practice to press to ensure the tuner has tuned for minimum SWR.

COMPUTER [\ TRANSCEIVER INTERFACE

The TS-870S interfaces easily with a computer. Computer interfaces on transceivers have encouraged the development of software applications by many companies.

Now available are electronic logbook applications that are partially self-completing. Information transferred between the transceiver and the computer is written into the logbook. These applications can automatically track awards and look up callbook information too.

Imagine using a mouse click to change your TS-870S to the correct DX frequency and mode of a DX station after the arrival of a report from your local DX packetcluster. Efficient operating technique is the key to winning in pileups and is essential when operating contests.

Other applications can change your computer into an electronic console from which you can remotely control functions on the TS-870S without physically touching its Front Panel. This capability makes possible remote operation of your transceiver from across the room,

from another room, or, when coupled with other commercially available products and where lawful, from another city via a telephone connection.

The list of applications is large and expanding, and is limited only by the imagination of software programmers. In short, the COM connector adds a new level of flexibility and opportunity to enjoy Amateur radio when a transceiver control application that supports the TS-870S and a computer are used.

Before using a computer for transceiver control, you should be aware of a few points. After you manually switch OFF the transceiver power, you can then switch ON the transceiver power using commands from the computer. Similarly, after switching OFF the power from the computer, it is then possible to switch ON the power from the Front Panel.

You can use the Front Panel controls while using computer control. Settings done from the Front Panel are effective immediately. After power is switched OFF from the computer, all values and settings per the Front Panel controls are restored.

COMMUNICATION PARAMETERS

In order to control the transceiver with your computer, you must first choose the communication parameters that you require. Configure your transceiver control application for 8 data bits and no parity. The communication speed and number of stop bits must match the settings in the TS-870S. The transceiver is configured via Menu No. 56 (COM.RATE). After changing Menu No. 56, the TS-870S must be switched OFF and then ON again for the new parameters to become effective. The defaults in the TS-870S are 9600 bps and 1 stop bit.

SLOPE TUNING (SSB/AM)

Changing the positions of the LO/WIDTH and HI/SHIFT controls while in SSB or AM mode changes the cut-off frequencies for the receive pass band. Controlling the pass band in this way allows you to eliminate adjacent frequency interference.

Turn the LO/WIDTH control clockwise to raise the high-pass filter cut-off frequency; turn it counterclockwise to lower the cut-off frequency. This is effective in removing interference from frequencies lower than your current operating frequency.

LO/WIDTH

Turn the HI/SHIFT control clockwise to raise the low-pass filter cut-off frequency; turn it counterclockwise to lower the cut-off frequency. This is

effective in removing interference from frequencies higher than your current operating frequency.

SHIFT

Be aware that shifting the CW center frequency does not automatically adjust the receive CW pitch. Therefore, it is possible to shift the CW pass band such that the selected CW pitch frequency falls outside the pass band. Doing this makes the CW signal inaudible.

Example:

Before adjusting IF Shift:

•CW pitch: 900 Hz

•IF Shift: 800 Hz (center frequency)

• CW Width: 600 Hz

In this example, the pass band would lie from 500 ~ 1100 Hz (from 300 Hz below the center frequency of 800 Hz to 300 Hz above the center frequency). If the CW pitch was set for 900 Hz, the signal would be audible.

After adjusting IF Shift:

•CW pitch: 900 Hz

•IF Shift: 500 Hz (center frequency)

• CW Width: 600 Hz

IF SHIFT (CW)

For CW, the center frequency of the filter pass band can be shifted without changing the current receive frequency. This is an additional method of fighting

adjacent frequency interference. Change the CW center frequency by adjusting the HI/SHIFT control. When the control is adjusted, “SHIFT” and the newly selected center frequency appears on the Display.

500 800 1100

200 500 800

Now, the pass band would lie from 200 ~ 800 Hz. With the CW pitch set for 900 Hz, the signal would not be audible since the pitch frequency is 100 Hz above the upper edge of the pass band. In this case, to make the signal audible, lower the CW pitch frequency by at least 100 Hz.

AUTO NOTCH (SSB)

Auto Notch automatically locates and attenuates interfering tones within the receive pass band. This function operates digitally at the IF level, hence it can affect your S-meter reading, and may affect (slightly attenuate) your desired signal. If interfering tones are weak, you may find that Beat Cancel eliminates them more effectively. Also, Auto Notch may not notch out signals inside the pass band if signals just outside the pass band limits are stronger.

After switching ON the function, selecting a mode other than SSB will switch OFF the Auto Notch function (LED goes out). Changing back to SSB re-activates the function automatically (LED lights). If strong, steady interference is present, switching Menu No. 18 (TRACK) to OFF may improve the notching capability. To block CW interference, switch TRACK to ON, then switch TRACK to OFF to lock the adaptive filter.

ADAPTIVE FILTERS

The Auto Notch, Beat Cancel, and Noise Reduction functions accomplish their design purposes by modifying the characteristics of adaptive filters. Adaptive filters adapt or change their characteristics according to the nature of the signal being received at a given moment. Menu No. 18 (TRACK) determines whether the adaptive filters are allowed to change in this manner or not.

It is also possible to specify how long the received signals will be monitored before determining filter characteristics. This monitor period is inversely proportional to the response time. The longer the monitor time, the slower the response time and vice versa. Use Menu No. 14 (LINE.ENH) to select a different Line Enhance response time, Menu No. 16 (SP.BEAT) for the Beat Cancel response time, and Menu No. 17 (SP.NOTCH) for the Auto Notch response time.

The adaptive filters may not function correctly with signals that have a poor signal-to-noise (S/N) ratio. Under poor conditions, you may find that optimum results are obtained by switching OFF the adaptive filters via Menu No. 18 (TRACK).

Note:

Only Auto Notch, or Beat Cancel, or Noise Reduction can be used at one time. They cannot be activated at the same time. Also, Menu No. 18 changes to its default setting when the TS-870S power is switched OFF and then ON again.

BEAT CANCEL (SSB/AM)

Beat Cancel also attenuates unwanted tones within the pass band, but it is more capable than Auto Notch at removing low-level tones. Also, this function works at the

AF level, therefore you will notice there is no S-meter signal loss, although the S/N ratio may be lowered in the AM mode.

After switching ON the function, selecting a mode other than SSB or AM will switch OFF the Beat Cancel function (LED goes out). Changing back to SSB or AM re-activates the function automatically (LED lights).

Press [BEAT CANCEL] to toggle the Beat Cancel function ON or OFF.

• The LED indicator in the button lights when the function is ON.

Note:

The effect of Beat Cancel may differ under different receiving

conditions even when using the same response time.

NOISE REDUCTION (SSB/CW/FSK/AM)

Menu No. 13 (LINE.ENH) determines whether the Line Enhance function (an adaptive filter) or the SPAC filter is used. When using the Line Enhance function, switch Menu No. 18 (TRACK) to ON. The SPAC filter works better for reducing noise and is effective for eliminating various types of noise. However, audio quality will deteriorate since only the audio portion is selected. This filter may induce pulse noises. One difference between the digital Line Enhance function and the conventional analog-based Noise Blanker is that the digital function works at audio frequencies whereas the blanker acts at IF.

Press [N.R.] to toggle the Noise Reduction function ON or OFF.

• The LED indicator in the button lights when the function is ON.

• When the S/N ratio is reasonably good in SSB, using Line Enhance will improve the S/N further. When receiving a CW signal with a poor S/N ratio, using SPAC will improve the S/N. For AM signals, received audio may become intermittent.

SETTING SPAC TIME

SPAC is a DSP term that literally means Speech Processing using Automatic Correlation. This is one method of digitally filtering out noise. Using Menu No. 15 (SPAC), select the correlation time that provides the highest quality reception for SSB. When receiving CW, choose the longest time that allows reliable reception. The longer the correlation time, the better the S/N .

Note:

If you are concerned about precise S-meter readings, switch ON Menu No. 11 (AIP.GAIN) when using this function. AIP.GAIN does not change the S-meter sensitivity but, due to the increased gain, the noise level increases even while receiving no signals. AIP.GAIN does not work in FM or AM.

ATTENUATOR

The Attenuator prevents distortion by reducing the level of the receive signal. The function is also useful to reduce interference from adjacent frequencies.

MEMORY FEATURES

MICROPROCESSOR MEMORY BACKUP

This transceiver uses a lithium battery to retain the userspecified memory items. Switching OFF the power will not erase the Menu Setups or memory channels. Lithium battery life is approximately 5 years.

If you find the transceiver powers-up with default settings, and VFO and memory channel data is erased, have the lithium battery replaced. Contact an authorized KENWOOD Service Facility or dealer.

CONVENTIONAL OR QUICK MEMORY?

Memory channels allow you to save various operating parameters (receive frequency, operating mode, etc.) for recall at a later time. You can store this data in Conventional or Quick memory. Conventional memory is used for storing data that you may want to recall many times in the future during different operating sessions. For example, Conventional memory is useful to store the frequency where you regularly meet your club members.

However, Quick memory is meant for quickly saving data without needing to specify a particular memory channel. It’s likely that you won’t need this data during future operating sessions. For example, as you tune across the band looking for DX, it is convenient to store stations that you want to contact into Quick memory. You can quickly jump between several different Quick memory channels as you monitor them.

MEMORY CHANNEL STORAGE

Memory channels can be either simplex or split-frequency. Simplex channels use the stored frequency for receiving and transmitting. Split-frequency channels use a different frequency for transmitting and receiving. Also, even if RIT or XIT is ON with a frequency offset selected, this offset will not be added to the frequency when it is stored.

■ Simplex Channels

QUICK MEMORY

Quick memory stores a maximum of five frequencies in a stack arrangement. As each new frequency is stored, all previously stored frequencies are bumped to their next respective Quick memory channel.

When all five channels contain frequencies, storing one more frequency then bumps all frequencies to the next channel and the frequency in Quick memory channel 5 is bumped off the stack and erased. Due to the stack configuration, it is not necessary to specify a memory channel when you save a frequency to Quick memory.

SCAN

Scan is a useful feature for hands-off monitoring of your favorite frequencies. After becoming comfortable with how to use all types of Scan, the monitoring flexibility gained will increase your operating efficiency.

This transceiver provides the following types of Scan:

Scan Type Purpose

Program Scan

Memory

Scan

All-channel

Scan

Group Scan

General update of activity on the entire band or a sub-section of the band while in VFO mode.

Quick activity update of all programmed Conventional memory channels.

Quick activity update of a selected group of Conventional memory channels.

PROGRAM SCAN

The Program Scan function scans the range between the Start frequency and End frequency stored in memory channel 99. If Program Scan is used before you store a Start and an End frequency, then the lower and upper frequency limits of the transceiver are automatically stored for the Start and End frequencies respectively. Some General market versions substitute the lower and upper frequencies for the current band in place of the frequency limits of the transceiver.

Program Scan direction is controlled by the Start and End frequency relationship. The following table summarizes the way that Program Scan functions:

For a refresher on how to store the Program Scan Limits, refer to “STORING SCAN LIMITS IN CH 99” {page 58}. The following are additional important points regarding the Program Scan function:

• Starting a transmission by closing the CW key, by sending a packet, or by triggering the VOX circuit by voice or the DRU-3 Digital Recording Unit stops Program Scan; however, transmission does not begin immediately.

• When the Program Scan range is smaller than a single step of the M.CH/VFO.CH control, turning this control causes Scan to jump to the lower of the Start/End frequencies, then continue scanning.

• Starting the Program Scan function switches OFF the RIT and XIT functions. RIT and XIT are not switched ON again when Program Scan stops, and the RIT/XIT offset frequency is not cleared.

•Operating mode can be changed while scanning.

• If Automatic Mode is switched ON, it will function with the Program Scan function.

Use the following procedure to activate Program Scan.

1 Select the VFO mode using VFO A or VFO B.

2 Press [SCAN].

3 To stop scanning, press [SCAN], or [CLR], or

[SEND], or Mic [PTT].

SCAN HOLD

While using Program Scan, if Menu No. 65 (PG.S.HOLD) is switched ON, then turning the Tuning or M.CH/VFO.CH control stops the transceiver from scanning for approximately five seconds. This is also true if Mic [UP] or [DWN] is pressed. Program Scan resumes after the five second pause. The default is OFF.

MEMORY SCAN

Memory Scan scans all memory channels containing data (All-channel Scan) or only a group of channels specified by you (Group Scan). This type of scan always ascends up through the channel numbers; the direction of scan cannot be changed. While scanning, if you want to skip over some programmed channels, turn the M.CH/VFO.CH control. Pressing Mic [UP] or [DWN] will also skip over channels but only during All-channel Scan.

All-channel Scan or Group Scan can be selected via Menu No. 66 (GRP.SCAN). The default is All-channel Scan (OFF).

The following are additional important points regarding the Memory Scan function:

• Starting a transmission by closing the CW key, by sending a packet, or by triggering the VOX circuit by voice or the DRU-3 Digital Recording Unit stops Memory Scan; however, transmission does not begin immediately.

• Starting the Memory Scan function switches OFF the RIT and XIT functions. RIT and XIT are not switched ON again when Memory Scan stops, and the RIT/XIT offset frequency is not cleared.

•Attempting to use Memory Scan when no data has been programmed in any memory channels, or when all channels are locked out, causes an alarm. Scan will not start.

•To scan channel 99, cancel Memory Channel Lockout {page 62} for that channel.

BUSY FREQUENCY STOP

The transceiver automatically stops Memory scanning when a signal is detected if Busy Frequency Stop is ON. The transceiver remains on the same channel for either a short time or until the signal drops depending on which Scan Resume method is selected (see below). The squelch must be adjusted to the noise threshold point with no signals present for Busy Frequency Stop to work.

Toggle Busy Frequency Stop OFF or ON via Menu No. 67 (BSY.STOP). The default is ON.

Note:

Busy Frequency Stop cannot be used with Program Scan.

■ Scan Resume Methods

Scan Resume controls when the transceiver continues Memory scanning after stopping due to a busy channel. Neither of the following two modes function if Menu No. 67 (BSY.STOP) is switched OFF. These modes cannot be used with Program Scan.

Time-operated mode: After stopping, Scan checks the busy channel approximately three seconds later. If the channel is still busy, Scan waits another three seconds then resumes scanning. If the channel is not busy three seconds after stopping, Scan resumes immediately.

Carrier-operated mode: Scan resumes approximately two seconds after the signal drops.

Select your preferred Scan Resume method via Menu No. 68 (CAR.SCAN). The default is Time-operated (OFF).

Note:

Remember to adjust the squelch threshold level {page 19}

before using Memory Scan.

ALL-CHANNEL SCAN

The All-channel Scan function scans all memory channels containing frequency data.

MEMORY CHANNEL LOCKOUT

Memory channels that you prefer not to monitor while scanning can be locked out. Lock out any memory channel with the following procedure.

1 Press [RX M.CH] to select Memory Recall.

2 Select the memory channel to be locked out.

3 Press [CLR].

• Release [CLR] immediately since pressing it for more than about 2 seconds erases the contents of the memory channel.

•A dot lights beside the right-most digit of the memory channel number to indicate the channel has been locked out.

SETTING SCAN SPEED

Scan speed can be changed through 9 steps using the RIT/XIT control. A weight value of the form “Pn” appears on the Display during Scan. “n” is a number from 1 to 9 that acts as a speed reference number. Turning the RIT/XIT control clockwise decreases the scan speed, and counterclockwise increases the speed. The Program Scan and Memory Scan speeds can be independently set as explained below.

The table below shows the time required for one frequency step (Program Scan) or one memory channel step (Memory Scan). For Memory Scan, if Menu No. 67 (BSY.STOP) is ON, the weight value is locked at 1. However, if Menu No. 67 is OFF, the stop time on each channel is as shown below.

PROGRAMMABLE FUNCTION BUTTONS

The Programmable Function provides a method for customizing the functions of four Front Panel buttons handily located around the Tuning control. If your operating habits or activities change, you can also easily change the functions that you assign.

This function gives you the capability to assign any of the functions from Menu Nos. 00 ~ 68 to certain buttons on the Front Panel. The programmable buttons are labeled ENTER, TF-SET, 1MHz, and FINE. Or you can assign functions (Nos. 69 ~ 73) to these buttons. If you want to keep the Front Panel as simple as possible, you can assign OFF to each button in which case the buttons will have no function.

Although the four buttons are automatically assigned with the labeled functions by default, you may prefer to re-assign these buttons, for example, with four of the DSP functions (Menu Nos. 13 ~18). This would allow you to experiment and learn how the different DSP settings affect received signals. Or, you could assign some of the AGC functions (Menu Nos. 01 ~ 07). Then you could make quick AGC changes, and choose the optimum settings to best match receive conditions.

There is a great deal of flexibility available with this function. Think about your operating priorities, then start assigning.

ALARM NOTIFICATION

An alarm will automatically alert you any time that your action requires the TS-870S to respond in a manner that is outside its set of defined parameters. The alarm may be configured for either three beeps or a Morse code message via Menu No. 37 (WARN. BP).

The messages that you will hear include:

QUICK DATA TRANSFER

The TS-870S has the capability to quickly and conveniently transfer the receive frequency, receive mode (computer command “0B”), and the transceiver ID (computer command “ID”) over to another compatible transceiver. Compatible transceivers include:

• TS-870S

• TS-950SDX

• TS-850S

• TS-690S

• TS-450S

This function could be useful while contesting. A spotting station that is searching for new contest multipliers can quickly transfer a frequency over to the running (main) station. Even as a single operator, with a little practice, you could use this Transfer function for transferring frequencies from a spotting transceiver over to your running transceiver. In this way, you get part of the benefit of a multi-operator team while still operating as a single-operator entry; an easy way to give a significant boost to your score. The Transfer function is fast, efficient, and increases your chances of working multipliers that you might miss otherwise due to holding a frequency by calling CQ.

Besides contest operation, the Transfer function can also prove useful if you enjoy monitoring more than one frequency simultaneously during day-to-day operating. Even if monitoring another band, you can quickly transfer any frequency over to your main transceiver and be ready to make a call fast enough to beat the DX packetcluster crowd.

SETTING UP

■ Equipment Needed

• TS-870S transceiver

• Compatible transceiver

• Interconnecting cable

•IF-232C (only necessary if transferring data to a transceiver other than the TS-870S)

The cable ends must be terminated with a 9-pin RS-232C female connector to mate with the TS-870S COM connector and a 6-pin DIN male connector to mate with the ACC 1 connector on any of the other transceivers. If using two TS-870S transceivers, then both ends need a 9-pin RS-232C female connector. The cable must also have the TXD/RXD and CTS/RTS wires crossed respectively so the cable will act as a null modem when connected between the transceivers.

If two TS-870S transceivers are connected together, the same COM connector baud rate must be used on each transceiver. If transferring to or from other KENWOOD transceivers, select 4800 bps and 2 stop bits on the TS-870S.

■ Connections

Connect each end of the interconnecting cable to the COM connector or the ACC 1 connector on the transceivers.

DSP-100 Users:

DSP Unit with the Transfer function. Connect the interconnecting cable to either the CONT IN or CONT OUT connector on the DSP-100, then connect the unused CONT connector on the DSP-100 to the ACC 1 connector on the transceiver. The transceiver connected to the CONT IN becomes the Master; the transceiver connected to the CONT OUT connector is the Slave.

You may continue using your DSP-100

USING QUICK TRANSFER

Note:

While transmitting data, other functions may work more

slowly.

■ Transferring Data

The Master is the transceiver that sends data to the Slave transceiver. If the Master has the RIT function switched ON, the RIT offset frequency is added to the receive frequency to be transferred.

1 Switch ON the Transfer function on each

transceiver.

• On the TS-870S, activate Menu No. 54 (TRNSFER) function. For the compatible transceiver, check your Instruction Manual for the correct method.

2 On the Master transceiver, press

QUICK MEMO [M.IN].

• If the Master is a TS-450S/690S, press

[M.IN], select memory channel 00, then press [M.IN] again.

• The displayed receive data is stored in Quick memory channel 1 on the Master transceiver (TS-450S/690S: channel 00) and transferred to the Slave transceiver.

■ Receiving Data

There are two ways that the Slave can receive the data from the Master:

• Quick memory 1 (TS-450S/690S: channel 00), or

• VFO

This choice is made on the Slave transceiver. On the TS-870S, Menu No. 55 (DIRECT) can be set to OFF to receive data into Quick memory, or to ON to receive data in a VFO. Check your Instruction Manual for other transceivers. Set Menu No. 27 (TX INH) to ON for a Slave TS-870S.

When receiving data at the Slave transceiver in the VFO, the data is transferred to the TX side of the VFO that is currently selected. If the transferred frequency is simplex, both the RIT and XIT on the Slave are set to OFF; if a split frequency is transferred then XIT is set to OFF but RIT is not changed on the Slave. The IF filter is determined by the transferred mode. AIP status is determined by the transferred receive frequency according to the AIP band memory.

If the Slave transceiver has a Quick or Conventional memory channel recalled for transmit when the transfer is done, the data will be rejected. To receive data into a VFO, select TX and RX using VFOs.

DRU-3 DIGITAL RECORDING SYSTEM (OPTIONAL)

The DRU-3 DRS unit allows you to record approximately 15 seconds of audio per channel on up to 4 channels. The audio is input via your transceiver microphone. Once recorded, the audio can then be transmitted. It is also possible to make longer messages by consecutively sending the contents of message memories. Finally, you can even send this longer linked message repeatedly by using the Repeat function accessible via Menu No. 39 (REPEAT).

The DRU-3 is useful in many situations:

• DX chasing or contest operation where repeated calls are necessary for extended periods of time

• Checking interference complaints to other equipment (lets you be in two places at one time)

• Checking or adjusting your transmit signal or your antennas if it’s not convenient to be sitting in front of your microphone

• Helping a friend adjust his antenna or receiver when he needs repeated test transmissions from you

Once you begin using the unit, you’ll likely discover other applications.

APPENDIX A: LEARNING ABOUT DSP

First-time users of a DSP transceiver may feel bewildered by the quantity of functions that they have never encountered on previous transceivers. When combined with the collection of new terminology that accompanies DSP, even an experienced operator may become frustrated. The purpose of this section is to offer a few examples that help you to begin learning about the effects and benefits of DSP. It’s best to read this section after you are comfortable with using the Menu system, and after you are fully familiar with the controls and buttons on the TS-870S. This manual will not make you an expert on using the DSP functions; that knowledge will come as a result of hands-on experience with the TS-870S.

Regardless what style of operating you prefer, DSP can help you. What operator doesn’t want the quiet, low-noise pass band offered by DSP operating in the IF stages? Who doesn’t want to effortlessly eliminate interfering tones caused by others tuning up near their operating frequency? Why wouldn’t anybody want to narrow their CW bandwidth to a razor-thin slice of spectrum if they can still listen to a pleasing CW note without analog filter “ringing”? These are only a few examples where DSP shines.

To begin with, the default Menu values chosen for the DSP functions on the TS-870S Menu have been carefully considered by the design engineers. They are good starting points. If you have already changed many Menu items as you’ve experimented with your new transceiver, do a Temporary Menu Reset {page 24} or a Full Reset {page 63} so that you know you are starting with the default Menu values.

Switch over to an Amateur band with lots of activity. Tune in an SSB station with reasonable signal strength. Press [N.R.] to activate Noise Reduction. You will hear a drop in the background noise that makes listening to the signal much more pleasant. If your station is located in an electrically noisy city, this function alone may make you a DSP believer. Assuming the default Menu values are selected (due to the reset above), you are now using the Line Enhance function (Menu No. 13 is ON). This function is “tracking” (Menu No. 18 is ON) the signal as the unwanted noise is removed.

Try changing Menu No. 14 to reduce and increase the response time of the Line Enhance function. What do you notice? Maybe little change can be heard with this signal or maybe you hear an important change. The longer you allow DSP to monitor the signal, the better the adaptive filters can determine how to fight the noise that is present. But there are tradeoffs. Monitoring a particular signal for too long will mean that the transceiver responds too slowly. Experiment and listen.

Switch OFF Menu No. 13. You are now using the SPAC filter. Listen for a change in audio quality as you switch Menu No. 13 OFF and ON. While Menu No. 13 is OFF, change the setting for Menu No. 15 to select a different correlation time for the SPAC mode. If you can’t hear a significant difference for the current receiving situation, then select a longer SPAC time for better audio quality. Although you may prefer the audio produced when, for example, the Line Enhance function is ON, remember

that different signal and band conditions can produce different results. Try not to come to any conclusions about which settings are best at this early stage. Keep an open mind until you’ve done a lot more experimenting on various bands with different propagation conditions.

Widen the receive pass band by turning the LO/WIDTH control counterclockwise and the HI/SHIFT control clockwise. Try to find a QSO in progress between two stations who are experiencing interference from a third station that may be tuning slightly off frequency but within your pass band. Press [BEAT CANCEL]. You may think the tuning station stopped transmitting. Press [BEAT CANCEL] again to switch OFF the function. The station is still tuning and you can hear it again! Beat Cancel can be so effective at automatically finding and canceling tones that are audible in the pass band that you may not be aware of the “interfering” stations at all. With Beat Cancel ON, experiment by changing the Beat Cancel response time via Menu No. 16. The response time of the function decreases as the setting number increases (selection 0 has the fastest response time).

Press [AUTO NOTCH]. Since Auto Notch functions in the IF stages, it may work better or worse than Beat Cancel for a given situation. Compare the effect of Auto Notch versus Beat Cancel with the same interfering tone or tones. Change Menu No. 17 to try different response times for Auto Notch while that function is activated. Experiment and listen.

If you are a CW operator, switch to the CW section of a band and search for a crowded portion. With the CW mode selected and the LO/WIDTH control turned clockwise to select a 1 kHz bandwidth, tune to a frequency where two or more stations are audible. Now turn the LO/WIDTH control counterclockwise to reduce the bandwidth. Forget old ideas associated with analog filters for how narrow you like the bandwidth when operating CW. With the minimum bandwidth, you may need to tune a little to center the desired signal in the pass band. Press [FINE] to reduce the tuning step to make tuning easier. Listen to the quality of the chosen signal. Can you believe the bandwidth displayed on the Front Panel? There are other functions to help you fight CW interference (such as IF Shift) but this example is to illustrate the benefits that DSP offers when using extremely narrow bandwidths.

After reading this manual, you should be equipped with the basic knowledge to begin learning how to use DSP to your advantage. The DSP benefits that you enjoy will be related to the amount of time that you spend experimenting with DSP while operating.

APPENDIX B: PROPAGATION INFORMATION

STANDARD TIME AND INFORMATION STATIONS

Besides providing an extremely accurate time source and other information, stations WWV and WWVH, in the continental U.S.A. and Hawaii respectively, deliver propagation announcements every hour in addition to acting as powerful beacons themselves. The announcements include information on geophysical alerts, solar activity, and more that all affects how well your signals will propagate to the DX station you’re trying to catch. If you can’t hear WWV/WWVH, then consult references such as the World Radio TV Handbook for information on some of the other standard time stations located closer to your area.

Check 2500, 5000, 10000, 15000, and 20000 kHz at 18 minutes after each hour (WWV), and 2500, 5000, 10000, and 15000 kHz at 45 minutes after each hour (WWVH) to hear the propagation forecasts.

NCDXF/IARU BEACON NETWORK

The Northern California DX Foundation and the International Amateur Radio Union are cooperating to support this particularly useful on-the-air tool. The network is monitored by scientists, students, etc. as well as Amateur operators.

This group of stations are located in North America, the Pacific, eastern Asia, the Middle East, Europe, southern Africa and South America, and more stations continue to be added to the network. They transmit beacon signals on 14100 kHz consecutively in sequence at power levels from 100 watts down to 100 milliwatts. You can listen to each station transmit with a known power from a known direction and location.

With minimal effort, in a brief time you can compile a customized and accurate profile of HF propagation conditions at your location. This information will help you decide where to point your antenna to look for DX or to call CQ. You could even distribute the information via packetcluster to local friends for their benefit. Or, because of the very precise timing used for each transmission, possibly you could develop an automatic means of monitoring the beacon frequencies, then assemble the recorded signal levels into a meaningful database for later consultation.

APPENDIX C: GENERAL COVERAGE RECEIVER FOR SWLING

The path that led many Amateurs to their first license included hours spent scanning the international shortwave broadcast bands. Often, inferior receivers that were readily available were used in those days. With your TS-870S, you now have the opportunity to re-visit those same crowded broadcast bands, but truly enjoy the myriad of stations that can be heard. For those who have never explored the shortwave broadcast bands, try listening and discover a world quite different from the Amateur bands.

Even if you have no interest in the transmission content from international broadcasters, noting which stations are present on which bands is another way to stay in touch with current propagation. Also, listening to native speakers of foreign languages is the best way to improve your listening comprehension of that foreign language. This could all help your Amateur activities.

Erecting a new antenna specifically for the broadcast bands is probably not necessary. Just use your Amateur antennas. Having a high gain antenna is usually not important; using the correct selectivity is the key to enjoying your listening.

16 m: 17480 ~ 17900 kHz

19 m: 15100 ~ 15800 kHz

22 m: 13500 ~ 13870 kHz

25 m: 11600 ~ 12100 kHz

31 m: 9400 ~ 9990 kHz

41 m: 7100 ~ 7350 kHz

49 m: 5900 ~ 6200 kHz

60 m: 4750 ~ 5060 kHz

75 m: 3900 ~ 4000 kHz

90 m: 3200 ~ 3400 kHz

120 m: 2300 ~ 2495 kHz

To handle the extremely crowded broadcast bands, you have many tools available on the TS-870S. For example:

•Store frequencies into consecutive memory channels for a broadcaster that is using parallel frequencies for a single transmission so you can quickly compare conditions on different bands.

•Try the LSB or USB mode and zero beat instead of using the AM mode. This will increase the intelligibility of some stations on crowded bands.

•Try different positions of the LO/WIDTH and HI/SHIFT controls to maximize sound quality but minimize interference.

• Dedicate either Menu A or Menu B as an SWL profile so you can quickly switch between Amateur and SWL settings.

•Switch ON the AIP function to reduce interference.

• Set Menu No. 43 (CH. STEP) for 5 kHz steps so the M.CH/VFO.CH control will step conveniently between broadcast channels.

• Set Menu No. 44 (STEP.ADJ) to ON so that rounding will occur on the next use of the

M.CH/VFO.CH control. This allows you to use the Tuning control to tune across a station, then later

continue stepping up the band from channel to channel with the M.CH/VFO.CH control.

• Consider using the COM connector to control the TS-870S from a computer. Software databases are available that can be used to quickly select the correct station frequencies for different broadcasters. This lets the computer keep track of where broadcasters are located, you only decide which stations that you want to hear.

Writing for many different program schedules is probably not necessary. There are numerous sources of scheduling information. Check your local packetclusters, packet networks, telephone BBS nodes, and interactive computer networks. Local newsstands may carry copies of SWL magazines and comprehensive books such as the “World Radio TV Handbook” or “Passport to World Band Radio”. Or simply listen on the broadcast bands and you may find SWL programs that announce current frequencies and languages being used by different broadcasters.

The TS-870S uses a full-duplex, asynchronous, serial interface for communicating through the male 9-pin RS-232C COM connector. Bytes are constructed with 1 start bit, 8 data bits, and 1 stop bit (4800 bps can be configured for 1 or 2 stop bits). No parity is used. The pinout and the pin functions of the COM connector are as shown below:

Pin No.

RXD: The transmit data is the serial data transferred from the transceiver to the computer. The output uses negative logic.

TXD: The receive data is the serial data transferred from the computer to the transceiver. The input uses negative logic.

GND: This is the signal ground pin.

RTS: This signal is applied to the transceiver. It is used

to inhibit transmit data from the transceiver when the computer is not ready to receive the data. The input uses positive logic. Inhibit is requested when the level is low.

CTS: This signal is applied from the transceiver. It is used to inhibit transmit data from the computer when the transceiver is not ready to receive the data. The output uses positive logic. Transmit data is stopped when the level is low.

CONTROL OPERATION

Most computers handle data in the form of “bits” and “bytes”. A bit is the smallest piece of information that the computer can handle. A byte is composed of eight bits. This is the most convenient form for most computer data. This data may be sent in the form of either serial or parallel data strings. The parallel method is faster but more complicated, while the serial method is slower and requires less complicated equipment. The serial form is, therefore, a less expensive alternative.

Serial data transmission uses time-division methods over a single line. Using a single line also offers the advantage of reducing the number of errors due to line noise.

Only 3 lines are required theoretically for control of the transceiver via the computer:

•Transmit data

• Receive data

• Ground

From a practical standpoint, it is also necessary to incorporate some means of controlling when this data transfer will occur. The computer and transceiver cannot be allowed to send data at the same time! The required control is achieved by using the RTS and CTS lines.

For example, the transceiver is placed into the transmit mode whenever the character string “TX;” is sent from the computer. The character string “TX;” is called a command. It tells the transceiver to do something. There are numerous commands available for control of the transceiver. These commands may be incorporated into a computer program written in any high level language. Programming methods vary from computer to computer; therefore, refer to the instruction manuals provided with the terminal program and computer.

COMMANDS

A command is composed of 2 alphabetical characters, various parameters, and the terminator to signal the end of the command.

EXAMPLE: Command to set VFO A to 7 MHz

FA 00007000000 ;

PARAMETER DESCRIPTION

Parameters are used to specify information necessary to implement the desired command. The parameters to be used for each command are predetermined. The number of digits assigned to each parameter is also predetermined. If a particular parameter is not applicable to the TS-870S, the parameter digits should be filled using any character except the ASCII control codes (00 to 1Fh) and the terminator (;).

BAD COMMAND EXAMPLES:

IS1000; Not enough parameters specified

(No direction given for the IF shift)

IS+100; Not enough digits

(Only three frequency digits given)

IS_+_1000; Unnecessary characters between

parameters

IS+10000; Too many digits

(Five frequency digits given)

For example, note the following in the case of the FA command (Frequency of VFO A):

•To set the frequency to 7 MHz, the following command is sent from the computer to the transceiver:

“FA00007000000;” (Set Command)

•To read the frequency of VFO A, the following command is sent from the computer to the transceiver:

“FA;” (Read Command)

• When the Read Command above has been sent, the following command is returned to the computer:

“FA00007000000;” (Answer Command)

Message

• Command syntax was incorrect.

Reason for Error

• Command was not executed due to the current status of the transceiver (even though the command syntax was correct).

Note: Occasionally this message may not appear due to microprocessor transients in the transceiver.

A communication error occurred such as an overrun or framing error during a serial data transmission.

Receive data was sent but processing was not completed.

COMMAND USE PRECAUTIONS

1 Do not use the control characters 00 to 1Fh since

they are either ignored or cause a “?” answer.

The Set command requires a " " (ASCII code 20h) in the third byte position. Insert " " for bytes that have no

;

characters to make a 28-byte fixed length command. The " " bytes will not send any character. Supported characters include: Letters, numbers, " ' (( )) ( ) The internal buffer allows approximately 5 times 28 characters (~140 characters) to be continuously keyed. For programs that convert to Morse code immediately after entry, more continuous keying is possible Ex: CQ CQ CQ DE WD6DJY WD6DJY WD6DJY K KY_CQ_CQ_ CQ_DE_ WD6DJY_ WD6DJ; KY_Y_ WD6DJY_K_______________ ;
