3. INSTALLATION AND CONNECTION

3-1. INSTALLATION

■FRONT FEET By extending the front feet, the front panel can be elevated for operating convenience. Turn the front foot left and pull down. Then turn right to lock.

3-2. CONNECTION

The TS-850S requires more than 20.5 A at 13.8 VDC when transmitting at full power. Use the PS-52 power supply for fixed station operation.

A. Rear Panel

Page 8

(1) Antenna (4) Key connection

Caution

Protect your equipment — Use a LIGHTNING

ARRESTER.

The type of antenna that is used will greatly affect

the performance of the transceiver. Use a properly adjusted antenna, of good quality, to enable your transceiver to perform at its best. The antenna input impedance is 50 ohms. Use 50-ohm coaxial cable such as 5D-2V or RG-213/U (RG-8A/U) for this connection. If the antenna is far from the transceiver the use of low loss coaxial cable, such as 5D-2V or

RG-213/U (RG-8A/U) are recommended. Match the

impedance of the coaxial cable and that of the antenna so that the SWR is less than 1.5 to 1. The protection circuit in the transceiver will activate if the SWR is particularly poor (greater than 3 to 1). High SWR value will cause transmitter output to drop, and may lead to TVI or BCI reports.

(2) Grounding

Caution Never use a gas pipe or electrical conduit pipe.

Notes

1. A ground connection that is a 1/4 wavelength or its multiple may provide a good DC ground, but it will not provide a good RF ground.

2. A city water pipe cannot be used as a good earth in some cases.

Your key should be connected as illustrated in the

figure below. When using an electronic keyer, make

sure that polarity is set for positive. Always use shielded line from the key to transceiver, (diameter

6.0 mm) |To use external straight key

+5V, Contact Current about 1 mA

Ground Not used +

Ground +

Note Check the polarity of the plug when you use an electronic keyer. Please refer to Section 4-4.

-I-5V, Contact

Current about 1 mA

Making a good earth connection is important for preventing dangers such as electric shock and for emitting a high quality signal with minimum spurious radiation. Bury a commercially available ground rod or copper plate under the ground and connect it to the GND terminal. A thick wire, cut as short as

possible, should be used for the connection. To make a good earth connection, connect the GND

terminal to a grounded metal water pipe. (3) External speaker

The TS-850S includes a built-in speaker. If you would like to use an external speaker, such as the SP-31, it may be connected to the EXT SP jack on the rear of the transceiver. The speaker may be any good 8 ohm permanent magnet type speaker. The diameter should be at least 4 inches for good audio quality. If you plan on using a speaker other than the SP-31 it should be equipped with a miniature phone jack plug, (diameter 3.5 mm)

Page 9

B. Front Panel

(1) Headphones Any low-impedance (4-16 ohms) headphone may be

used with the transceiver. Connect the headphones to the front panel PHONES jack, (diameter 6.0 mm). The optional HS-5 or HS-6 headphones are best suited for use with the transceiver. Stereo type

headphones can also be used.

(2) Microphones Any microphone with an impedance to 6000 may be

used with this transceiver. The KENWOOD microphones MC-43S (handheld), MC-60A, MC-80,

MC-85 (table-top type) are recom-mended.

in SSB, AM or FM operations. Break-in operation is possible in CW operation. To activate the VOX

circuitry place the VOX switch ON(a).

0FULL/SEMI (Break-in) switch This switch affects the transmit/receive recovery

time. In the SEMI position the transceiver will key when the key is depressed and remain in the transmit position until a preset delay has been reached. In the FULL position the transceiver will return to receive as soon as the key is released, thus allowing you to copy incoming signals between characters.

® AlP (Advanced Intercept Point) switch

Use AlP when good signal reception can not be

obtained. When switched on, it reduces interference from strong signals. When the frequency falls below 9.5 MHz,

initialization takes place automatically.

____________

Note

When AlP is on, the sensitivity of the receiver is

reduced about 10 dB.

©HIGH BOOST switch

The high-frequencies of the transmit audio signal are

emphasized. Intelligibility may be improved,

depending on the characteristics of the microphone

and atmospheric conditions.

Page 11

@ Meter

During receive the meter is used as an S-meter. During transmit the meter is used as a POWER meter, and is controlled by the METER key, and provides either VSWR, COMP level or ALC level readings.

The meter can be used as a peak hold meter.

Please refer to Section 4-10-15.)

(i|) RIT/XIT frequency display

Shows the amount of RIT/XIT offset to the nearest 10 Hz. Minus “ —” appears in the display when the RIT / XIT offset is below the transmit / receive frequency. Shows the scan speed during scanning.

@ NOTCH control

The NOTCH function is used to reduce or eliminate

heterodyne, or CW type signals. The NOTCH filter

will not be effective against SSB, AM or FM type

signals.

Note This switch is disabled during FM operation.

@NB 1 switch For pulse type noise, such as generated by automotive ignition systems, turn the NB 1 switch ON. This switch will not help to eliminate atmospheric or

line noises, only pulse type noise.

(^ NB 2 switch

Noise blanker 2 is used for long duration pulse noise, like the “woodpecker”. To reduce “woodpecker” radar noise interference, set switch NB 2 to the ON position (NB 2’s effectiveness depends on the specific type of interference). If you use NB 2 for short duration pulse noise, the receive signal may become distorted, making it difficult to hear. Unfortunately no noise blanker can remove all different types of interference; but the two noise blankers that have been provided in the TS-850 are effective in most cases. If there is no “woodpecker” present, the switch should be in the OFF position.

@ SQL (Squelch) control This control is used to eliminate atmospheric noise,

and receiver static noise during no signal periods. Slowly rotate the control clockwise to the point where the ambient noise just disappears, and the speaker shuts off. This point is known as the squelch threshold point. Now you will only hear output from the speaker when an incoming signal is present. For weak signal reception this control should be fully counterclockwise.

@ NB LEVEL control Controls the noise blanker operating level. Use only the minimum level necessary.

(§) NB2 WIDTH control This control varies the width of the blanking pulse of

NB2.

Notes

1. The NB2 control only works on woodpecker type noise.

2. If the control is turned too far, the received

signal may be distorted. Set the control for the best receive signal.

(24) RIT switch Press to turn the RIT ON or OFF.

@XIT switch Press to turn the XIT ON or OFF.

® @ ® 0

(§) REC/SEND switch

This switch is used when you want to manually control transmit or receive.

REC : Places the transceiver into receive.

SEND : Places the transceiver into transmit. (§)THRU/AUTO switch

THRU : The auto antenna tuner is not used in

transmit.

AUTO: The auto antenna tuner is used in transmit.

(§) NOTCH switch

Effective transmit power output will increase when

the PROC switch is turned ON during SSB mode

operations.

Adjust the PROC control while speaking into the microphone in a normal tone of voice, for a peak COMP scale reading of no more than 10 dB. Do not overdrive the COMPRESSOR. Over driving the compressor will deteriorate voice quality, increase transmitter noise level, and in general make copying your signal more difficult.

MIC connector (Front view)

©AGO switch This switch selects the operating time constant of the AGO (Automatic Gain Control) circuit. When the AGC switch is set to SLOW, the receiver gain and

S-meter readings will react slowly to large input changes, and when set to FAST, the receiver gain and S-meter will react quickly to changes in the input signal level.

The normal position when using all modes is the

SLOW position. When working any of the following you might wish to use the FAST position.

• When tuning rapidly, use the FAST position.

• When receiving weak signals.

• When a high-speed CW signal is being received. Note

This switch is disabled during FM operation.

©MONI (Monitor) control This controls the volume of the transmit monitor. This control is operational in the SSB and FSK mode.

® MONI (Monitor) switch Allows monitoring of your transmit signal. This control is operational in the SSB and FSK mode.

® MIC gain control Microphone gain can be adjusted during SSB and AM operations. Gain is increased by turning the control clockwise.

Power can be controlled in all modes. Power is increased by turning the control clockwise. Keep the transmit power within the output power limits of your license.

©CAR (Carrier level) control

Used to adjust carrier level during CW, AM and FSK.

approximately 6 dB when this switch is activated.

The incoming receive signal level is attenuated by approximately 12 dB when this switch is activated.

The incoming receive signal level is attenuated by approximately 18 dB when both the 6 dB switch and 12 dB switch are activated.

This control is also useful when a strong signal is

near your desired signal; while some loss will occur to the desired signal, as well as the undesired signal, the use of the attenuator will sometimes allow you to

understand what is being received. For normal

receiver performance, this switch should be in the

OFF position.

(g) RIT/XIT control

RIT (Receiver Incremental Tuning)

The RIT control allows shifting the receiver frequency. Use of the RIT control will not affect

the transmit frequency. When the RIT switch is ON, the RIT indicator will light, and the receive frequency can be adjusted by using the RIT control.

Note When the RIT is ON the transmit frequency may be different from the receive frequency. For normal operation leave the RIT switch OFF. It should be used only when necessary.

The scan speed can be changed during scanning with the RIT control.

XIT (Transmitter Incremental Tuning)

XIT is very similar to RIT. XIT is only active in the transmit mode. By using the XIT function it is possible to offset the transmit frequency without the normal loss of receiver audio that is experienced when using the SPLIT function. The RIT / XIT offset can be preset, without affecting the actual operating frequency by turning OFF the RIT/XIT and using the RIT/XIT display to determine the offset. This is useful when working a DX station who is “split” within the XIT range.

The RIT / XIT step size is either 10 Hz or 20 Hz.

Please refer to Section 4-10-15 for information on how to select the desired step size.

@QUICKMEMOMRkey

This key recalls the quick memory.

@TONE control

Turn the control to increase or decrease the receiver audio tone.

Page 16

The standard position is with the control turned fully clockwise. As the control is turned counterclockwise,

high frequencies are cut.

(§)M.CH/VFO CH control

This control is used to select the desired memory channel during Memory Channel Operation. This control is also used to change the frequency in 10 kHz steps during VFO operations. The control is also used to select the desired power on function you wish to change. See section 4-10-

15. (g)AF gain control

Turn the knob to increase or decrease the volume.

Clockwise rotation increases the volume and counterclockwise rotation decreases the volume.

Note The output level of the “Beep” and “Sidetone” are not affected by adjusting of the AF gain control.

(§)RF gain control

This control adjusts the gain of the receiver highfrequency amplifier section. For normal receiver performance, and maximum gain, this control should be all the way to the right. If you are having trouble copying the desired signal make a note of the stations peak S-meter reading. Then, adjust the RF gain control left, so that the meter needle is stationary at this level. Now, all signals that were less than the desired signal will be attenuated, such as static noise, etc., making

reception easier.

If the incoming signal pegs the S-meter you can also reduce the receiver gain by moving the RF gain control to the left. The S-meter pointer will always advance up-scale as the RF gain control is moved, to indicate that the gain has been reduced.

(g) SLOPE TUNE LOW CUT control Adjust the LOW CUT control clockwise, and interference from signals lower than the operating frequency will be reduced. As with the HIGH CUT control, use of the LOW CUT control will also affect the audio frequency passband. In this case the low frequency components of the audio signal will be reduced.

Simultaneous use of the RF gain control and AGC switch

If a strong signal (such as a local station) appears in the vicinity of the intended receive signal, the S-

meter may show unusual deflection due to the AGC voltage developed from the strong disturbing signal.

If this occurs, move the RF gain control to the left so

the meter pointer remains at about the original

deflection peak and turn the AGC switch to the

FAST position. This will reduce the unwanted AGC

voltage and permit clear reception.

Note

This control is disabled during FM operation.

(§)SLOPE TUNE HIGH CUT control

Adjust the HIGH CUT control counterclockwise, and

interference from signals higher than the operating frequency will be reduced. The high-frequency components of the resulting receiver audio will also be reduced.

Note This control is disabled during FM operation.

4-3-2. Speech Processor

The Speech Processor is used when signals from your station are weak at the distant station.

During SSB operation (especially DX operations), it may be desirable to increase the relative “talk-power” of the transmitter by using the speech processor circuitry. This may make the difference between a marginal, and a copyable signal.

•Operation Turn the PROC switch ON and place the METER switch to COMP. Adjust the PROC control while speaking

into the microphone in a normal tone of voice, for a peak COMP scale reading of no more than 10 dB. Do not overdrive the COMPRESSOR. This will deteriorate voice quality, increase transmitter noise level, and in general make copying your signal more difficult. Next, set the METER switch to ALC and adjust the MIC gain control while speaking into the microphone. Ensure that the meter deflection is within the ALC zone!

4-4-1. CW zero-beat Operation

In CW operation equalizing the receiving frequency with that of your transmit is called “Zero beating”. The TS-850 enable you to zero beat in the following manner.

You can forceable change the ratio to you own personal preference or you can select AUTO

WEIGHT control where the weighting adjusts for

changes in keyer speed.

• Auto Weight (Initial state) [When the Power on function selection (Number 21) is ON.]

Press the TUNE key and adjust the tuning knob so that the signal from the other transceiver is zero beat, and deactivate the TUNE key. The CW can then be used with the other transceiver zeroed in.

1. If the VOX/MAN switch is VOX, set it to MAN and depress the key.

2. A side tone will be heard from the speaker.

3. Adjust the TUNING knob so that the transmit frequency of the station you are receiving is equal to the side tone frequency. Zero beating is now completed.

4-4-2. PITCH function

You can specify the desired pitch of the receive tone during CW reception.

1. Press the PITCH key during CW receiving.

2. Select the desired pitch with the M.CH/VFO CH control.

400-450 - 500-550-600-650 - 700

The dot-dash ratio can be set according to the

keying speed. The reverse mode can be turned on or off with the power on function (menu number 22). (Please refer to Section 4-10-15.)

4-4-3. Electronic Keyer Circuit Operation

Place the ELECTRONIC KEY switch on the rear panel to ON. Connect a paddle type key to the CW

KEY jack use a 6.0 mm diameter stereo plug. Adjust the KEY SPEED control for the desired speed.

■Weight Adjustment

The ratio of dot / space / dash can be adjusted as follows:

DOT SPACE

1 1

The dot-dash ratio has been factory preset to 1 : 3

and will remain so regardless of the keyer speed.

DASH

SPACE

Notes

1. It requires a little time to change the ratio at about the 3 and 7 positions of the KEY SPEED control where some hysteresis occurs.

2. These dot/dash ratios are only approximate.

• Manual Weight [When the Power on function selection (Number 21) is OFF.]

The dot-dash ratio can be set between 1:2.5 and 1:4.0 with the power on function (menu number 23). (Please refer to Section 4-10-15.)

For the CW message storing, see Section 4-13. DRS function.

■SEMI and FULL break-in operation

Two break-in methods are provided with the transceiver, SEMI and FULL break-in. With either

break-in operation, depressing the CW key will cause the radio to transmit without the need for manually switching the REC / SEND switch. The difference between FULL and SEMI break-in is that during FULL break-in operation it is possible to listen between dots and dashes, and that during SEMI break-in it is not.

Page 26

Note With either SEMI or FULL break-in operation, cross band / cross mode operation is not possible. Additionally, when you are using FULL break-in you should not work cross band splits, only in the same band.

This transceiver also provides a sidetone oscillator circuit to allow monitoring of your CW signal during transmission. (a) Semi-automatic break-in

Depressing the CW key will automatically place the transceiver into the transmit mode. Transmit mode will be maintained for a period determined

by the setting of the DELAY control on the front

panel of the transceiver, even after the CW key is

released.

(b) Full-automatic break-in

Depressing the CW key will automatically place the transceiver into the transmit mode. Releasing the CW key will return the radio to receive

immediately enabling reception between characters.

■ When the electronic keyer is used as Bug key

When the electronic keyer is used as the Bug key, turn the function on with the function setting (menu number 24) at power on. (Please refer to Section 4-

10-15.)

____________________________________

Note

When the ELECTRONIC KEY changeover switch

is on, menu number 24 is displayed.

Cautions

1. The TL-922 / 922A linear amplifier is not designed for full break-in type operation. Attempting to use this accessory in the FULL

break-in mode may cause damage to the linear amplifier.

2. The switching time between transmit and

receive decreases as you increase your keying speed. This limits the maximum keying speed that is available during FULL break-in operation. When using high speed

CW you should use SEMI break-in.

3. During SPLIT operations with FULL break-in,

clicks may be heard in the monitoring tone or received signal depending on the combination of the transmit / receive

frequencies.

4. During full break-in, the received audio that

passes through the 250 Hz band CW narrow filter may click because of its delay time.

5. If the TS-850S is used with CW filter YK88CN-1 (option) or YG-455CN-1 (option), it is not suitable for full break-in operation because it has a delay time when the signal passes through the narrow-band filter. In this case, you are recommended to perform SEMI break-in operations.

Since AFSK using the SSB mode is normally used for 300 baud packet transmissions, the AFSK signal is applied to

the MIC signal line. This is possible in both the USB and LSB modes, but the frequency of the signal that is actually transmitted is the display frequency plus the modulation frequency in USB mode, and the display frequency minus the modulation frequency in LSB mode. Since various modulation frequencies are used by different TNC’s, you

should determine the correct operating frequency, taking the AFSK frequency of the TNC that you are using into

Notes

1. Follow the instructions contained in your terminal units operating manual for the correct settings before you start transmitting.

2. If the output of the terminal unit causes the ALC meter to register above the recommended limits even with the MIC gain control turned all the way down you should reduce the output of the terminal unit. Excessive signal levels can cause distortion! If the terminal unit output level is fixed you should add a potentiometer between the transceiver and

the terminal unit. (Refer to Section 6-4-4.)

4-8-1. RTTY

RTTY operation requires a demodulator and a

teletypewriter. A demodulator including 2125 and

2295 Hz (170 Hz shift) filters, will be acceptable and may be connected directly to the REMOTE connector. To use the transceiver’s FSK circuit with older high voltage teletype equipment, you must use an external keying relay in the teletypewriter closed loop, and connect the relay contacts to the rear panel RTTY terminal. During FSK operation, the MARK frequency is shown on the display.

RTTY SYSTEM This transceiver will adapt to Slow Scan Television or AFSK (Audio Frequency Shift Keying) RTTY operation. For SSTV, the ACC 2 connector should be connected to the Camera output. The ACC 2 connector should be connected to the monitor input. For AFSK operation, connect the Tone Unit output to the ACC 2 input, and ACC 2 output to the Tone Unit input.

AFSK receive signal SS (Standby)

The figure below shows the frequency relationship

between receive and transmit with this transceiver. In FSK operation the mark frequency is indicated on

the display.

Speaker terminal

Normally a mark frequency is transmitted when the key is closed, and the space frequency is transmitted when the key is open. Since a

shorting pin is inserted into the RTTY terminal at the factory, the mark frequency is transmitted. The polarity can be reversed so that the mark frequency is transmitted when the key is open with a power on function. (Please refer to Section 4-10-15.)

4-8-2. DATA COMMUNICATIONS

(PACKET, AMTOR, RTTY, SSTV,

etc.)

1. The ACC 2 connector has been provided for connection of Data communications devices. All necessary connections can be accomplished from the same connector.

2. When using AFSK (Audio Frequency Shift Keying) or modulating the signal with any form of audio tones you should select LSB or USB. If F2 operation is desired select the FM mode. In general LSB is used for RTTY and PACKET communications in the HF band (FI), and USB is used for AMTOR.

3. The transceiver will transmit according to the signals received on the STBY connector. These inputs are generated by the terminal unit in response to inputs from the associated terminal input device.

4. When using LSB, or USB the MIC gain control should be used to adjust the input level for an on scale ALC meter reading.

5. Pin number 9 of the ACC 2 connector is used to disable the front panel microphone connector during the periods that your communication terminal is in use (grounding the pin accomplishes this task). This prevents unwanted errors from in your text.

Note The display frequency 14.200.00 MHz.

The BFO normally uses the LSB mode for RTTY operation. When the REV key is pressed, the BFO changes to the USB mode. In the FSK-R (FSK reverse) state, the display frequency is the space frequency. If the other transceiver is using reverse shift, the receiver polarity can be adjusted with the REV key. The display indicates the mark frequency even if the shift width is changed.

Page 36

4-9. AUTO ANTENNA TUNER

OPERATION

If the transceiver is operated into an antenna with a high SWR, the final stage SWR protection circuit may operate (when SWR is greater than approximately 2 : 1). Use of the Automatic Antenna Tuner will help you to match the antenna to the transceiver. The AT unit is capable of matching a 20

- 150 ohm load, or approximately a 2.5 : 1 SWR. If the antenna and feed line exceed this range the tuner may not be able to find the correct match. If the tuner cannot match after two attempts, check your antenna and feed lines. Output power of the transceiver will automatically be reduced to approximately 10 watts during the tuning process to protect the finals against damage.

______

Note The carrier control should be adjusted for normal CW output (at least 10 watts).

While the automatic antenna tuner is capable of reducing the apparent SWR of the antenna system,

it is important to remember that maximum power output will only occur when the antenna has been adjusted for the lowest possible SWR.

2. Set the AT TUNE switch to ON. The transceiver switches to the CW mode, the AT TUNE indicator lights, and the unit starts tuning.

Note This switch will not function when the CAR control is turned fully counterclockwise.

3. When tuning is completed and the AT TUNE indicator goes out, the frequency display returns automatically.

4. A warning beep tone is sounded if tuning is not completed within 20 seconds. If this occurs turn the AT TUNE switch OFF, and then repeat steps 1 - 3.

@ Manual Tune mode

Manual adjustment of the tuner is possible with the

tuning knob and M.CH/VFO CH control if auto-tuning

is not possible.

1. Press and hold the LSB/USB key while you turn on the POWER switch.

2. Select the number 20 by rotating the M.CH/VFO CH control. Use the UP/DOWN switch to select OFF.

The antenna tuner has the following three modes;

® Preset mode

This transceiver has a Preset Memory function

capable of storing tuning conditions of each amateur radio band. The transceiver stores the tuning conditions after tuning of an amateur radio band is completed, and automatically provides the stored

tuning conditions when switched backed to that

amateur radio band from other amateur radio bands, reducing the time for tuning. When you switch to an amateur radio band, the AT TUNE indicator lights briefly to indicate that the Preset function is operating.

1. Set the THRU/AUTO switch to AUTO. The AT TUNE indicator will light and the transceiver will adjust to it’s preset condition.

2. When preset is completed, the AT TUNE indicator turns off.

Note If you change BANDS and then return to the previously tuned BAND, after tuning is complete, the SWR may have changed. If the SWR has changed, set the AT TUNE switch to ON so the unit will retune.

3. Press the CLR key, or press the POWER switch OFF and then back ON.

4. Place the THRU/AUTO switch to AUTO.

5. Turn the AT TUNE switch ON. While reading the SWR meter, alternately turn and adjust the TUNING knob and M.CH/VFO CH control for the lowest SWR. When tuning is completed, the AT TUNE indicator will go out. Once it goes out, further tuning will not be possible even if you turn the controls.

6. The current setting is stored in memory as the preset data for the amateur band when the AT TUNE indicator turns off or you stop tuning by pressing the AT TUNE switch. If manual tuning is done in one band, then again

in another only, the tuning data for the first band is memorized. So, if the first band is reselected, the memorized tuning data is recalled, reestablishing the original tuning.

7. To cancel the manual tuning mode, perform step 1, select ON in step 2, and then step 3.

_________

Note If manual adjustment fails to lower the SWR and complete the tuning, adjust the SWR of the antenna.

In this mode, tuning signals are transmitted to tune

the antenna and transceiver automatically.

Note If switch SW 1 on the rear is set to EXT, the built-

in antenna tuner does not work.

4-10-7. Dual Digital VFO’s

Operational convenience is enhanced thru the use of two VFO’s. Two VFO’s are provided to allow you to change frequencies rapidly with the least amount of dial rotation. For example; you could set one VFO to the

lower tuning limit and the other VFO to the upper

tuning limit. A = B key

Depressing this key causes the data contained in

the inactive VFO (the VFO that is not currently

being displayed in the display area) to change to the same data that is contained in the active VFO (the one currently displayed). Both the frequency,

mode and filter selection are changed.

Note When a memory channel is being used reception, the A = B key will not function.

For example:

RX VFO A is set at 7 MHz in LSB, and RX VFO B

is 14 MHz in USB. RX VFO A is the active VFO

(shown on the display). Depressing the A = B key

will cause RX VFO B to change to 7 MHz in LSB.

for

To avoid confusion during contest, or pile-up operations we recommend using VFO A for receive and VFO B for transmit.

•TF-SET key

Depressing this key will allow you to rapidly set or check the transmit frequency, during SPLIT operations, without the need of actually transmitting.

This key is especially convenient when you are trying to locate the transmit frequency of the station currently in contact with the DX station, since depressing this key allows you to receive on the transmit frequency as long as the key is held depressed. The TUNING knob is active when this

key is depressed, so it is easy to change your transmitter frequency at the same time, if necessary.

Releasing the key will return you to the original

receive frequency.

4-10-9. Interference Reduction

■All mode [ I ] SLOPE TUNE control (Except FM mode)

During reception, these controls permit you to reduce the apparent IF filter bandwidth and therefore reduce adjacent channel interference.

•SLOPE TUNE HIGH CUT control

Adjust the HIGH CUT control counterclockwise, and interference from signals higher than the operating frequency will be reduced. The high-

frequency components of the resulting receiver

audio will also be reduced.

•SLOPE TUNE LOW CUT control

Adjust the LOW CUT control clockwise, and interference from signals lower than the operating frequency will be reduced. As with the HIGH CUT control, use of the LOW CUT control will also affect the audio frequency passband. In this case the low frequency components of the audio signal will be reduced.

Maximum bandwidth occurs with the LOW CUT

control fully counterclockwise, and the HIGH CUT

control full clockwise.

4-10-8. SPLIT FREQUENCY OPERATION

Different frequencies can be set for VFO A, VFO B and for memory. For example: VFO A is the active VFO, and VFO B is the inactive VFO. Depressing the TX VFO B key will cause the transceiver to receive on VFO A and transmit on VFO B. The mode of reception and transmission will follow the mode contained in the appropriate VFO. It

Note When bandwidth of the 8.83 MHz filter is approximately the same as that of the 455 kHz filter, the combined bandwidth will be narrower than the indicated bandwidth.

For example, when both the 8.83 MHz and 455

kHz filters are set to 2.7k, the combined bandwidth will be about 2.4 kHz.

[Ill] NOTCH control (Except FM mode) Use this control when you are experiencing interference from a CW heterodyne type signal. Turn

the NOTCH ON and slowly adjust the NOTCH

control to minimize the beat signal. A beat of approximately 1.5 kHz can be reduced at the approximate center position of the control. Please note that this control will not eliminate SSB, AM or FM type interference. The bandwidth of such signals

is approximately 3-6 kHz wide. When in the USB, CW or AM mode a beat tone lower than the center frequency can be reduced by rotating the control clockwise from the center point. In LSB or FSK mode adjust the control counterclockwise.

Notes

1. The NOTCH frequency can be varied within a range of approximately 400 to 2600 Hz.

2. When an interfering signal such as a CW station

appears, slowly rotate the NOTCH control. If you rotate the knob too quickly you may pass

right over the notch point. Slow rotation will yield best results.

3. The NOTCH frequency may be shifted by the SLOPE TUNE position. Operate the SLOPE

TUNE control, then the NOTCH control.

4. If the NOTCH frequency equals the frequency of the desired signal (SSB), the desired signal is attenuated slightly, but this is not in an error.

5. Since the notch is a filter with a very sharp attenuation characteristic, the adjustment point may be shifted. (Please refer to Section 6-6-6.)

4-10-10. Noise Blanker

•NB 1 switch For pulse type noise, such as generated by

automotive ignition systems, turn the NB 1 switch

ON. When pulsating noise, such as that caused by automobile ignitions is encountered, place the NB

1 switch ON.

This switch will not help to eliminate atmospheric or line noises, only pulse type noise.

•NB 2 switch Noise blanker 2 is used for long duration pulse noise, like the “woodpecker”. To reduce “woodpecker” radar noise interference, set switch

NB 2 to the ON position (NB 2’s effectiveness depends on the specific type of interference). If you use NB 2 for short duration pulse noise, the

receive tone may become distorted, making it difficult to hear.

Unfortunately no noise blanker can remove all different types of interference; but the two noise blankers that have been provided in the TS-850 are effective in most cases. If there is no “woodpecker” present, the switch should be in the OFF position.

•NB LEVEL control Controls the noise blanker operating level. Use only the minimum level necessary.

>NB2 WIDTH control

Controls the width of the blanking pulse when NB 2 operates. Adjust the width so that the desired signal can be received most clearly.

Notes

1. The control only works when there is woodpecker noise.

2. If this control is turned too far, the received signal may be interrupted. Set the control to the best position.

4-10-11. VOX OPERATION

Depress the VOX switch. While speaking into the microphone, increase the GAIN control until the VOX relay just operates. Clockwise rotation of this control will increase the sensitivity. For VOX operation it is sometimes desirable to “Close-Talk” the microphone in order to prevent background noises from tripping the transmitter.

1. Check that the ALC reading on voice peaks is still within the ALC zone on the meter. If necessary,

readjust the MIC gain control for the proper ALC reading.

2. If the VOX circuit is activated by the output from the speaker, adjust the ANTI control as necessary for proper VOX operation.

3. Do not use excessive VOX or ANTI VOX settings. This may cause the VOX circuit to operate erratically. Use only the minimum necessary control setting.

4. If the VOX circuit transfers between words, or

holds too long, adjust the release time-constant using the DELAY control.

4-10-12. ON AIR MONITOR

Turn the MONI switch ON to monitor the transmitted signal. Headphones are

recommended.

II. MONI control

Adjust monitor volume level.

Note

This function is not active in the AM and FM mode.

4-10-13. RIT control

The RIT control allows shifting the receiver frequency ±1.2 kHz. Use of the RIT control will not affect the transmit frequency. The RIT step size is either 10 Hz or 20 Hz. (Please refer to Section 4-10-15.) When the RIT switch is ON, the RIT indicator will light, and the receive frequency can be adjusted by using the RIT/XIT control.

Page 41

Note When the RIT is ON the transmit frequency may be different from the receive frequency. For normal operation leave the RIT switch OFF. It should be

used only when necessary.

4-10-14. XIT control

Transmitter Incremental Tuning is very similar to

RIT. XIT is only active in the transmit mode. By using the XIT function it is possible to offset the

transmit frequency without the normal loss of

receiver audio that is experienced when using the

SPLIT function. The XIT step size is either 10 Hz or

20 Hz. (Please refer to Section 4-10-15.)

Offsets of ±1.2 kHz are possible. The RIT/XIT offset can be preset, without affecting the actual operating frequency by turning OFF the

RIT/XIT and using the RIT/XIT display to determine the offset.

4-11. MEMORY

4-11-4. Memory Contents

The transceiver incorporates a convenient 100 channel memory that can be used to store and recall commonly used frequencies.

4-11-1. Microprocessor back-up lithium

battery

A lithium battery is contained in the transceiver to

retain memory. Turning off the POWER switch, disconnecting the power cable, or a power failure will not erase the memory. The battery should last for

approximately five years. When the battery

discharges, an erroneous display may appear in the display. Lithium battery replacement should be performed by an authorized KENWOOD service

facility; either your KENWOOD servicing dealer

authorized service center, or the factory, since this unit contains CMOS type circuitry.

(1) Features of each Mode

®SSB mode

Modulation of higher quality than a usual SSB mode is obtained through modulation by the 10th phase-shift network that digitally processes

signals.

(Dew mode

Excellent characteristics are obtained through digital form-restoration of the wave shape.

(Dam mode

Low-distortion modulation with excellent amplitude and group delay characteristics is obtained

through digital modulation and by using the 84th

FIR filter.

@FSK mode

Excellent, low-distortion modulation is obtained

through FSK modulation with continuous phasing

after the digital form-restoration.

(DSSB, CW, and FSK mode (receive)

Received SSB, CW, and FSK signals are detected by the DSP.

(2) Operation

(DMicrophone gain adjustment

When the DSP-100 TX switch is on, the microphone gain in the SSB and AM modes is adjusted with the DSP-100 MIC GAIN control so that the TS-850 ALC meter pointer does not exceed the ALC range.

4-20. Remote control function

The front panel keys can be operated remotely via the remote control terminal (ACCS) on the rear. The

following eleven functions can be remotely controlled.

PLAY-1, PLAY-2, PLAY-3, REC-1, REC-2, REC-3, CLR,

TF-SET, QUICK M.IN, QUICK MR, VOICE

The remote control terminal circuit in the transceiver is as follows. When the A/D converter terminal voltage

reaches the voltage determined by the built-in program, the microprocessor performs operations according to the terminal voltage. For example, if a 4.7kohm resistor is connected between + and — of the remote control terminal, the A/D converter input voltage becomes about 2 V, and the QUICK MR function operates. You can make your own remote control keyboard to suit your needs by providing the necessary remote control switches.

The terminal voltages and resistance values required for operating each of the functions are as follows:

Function

PLAY-1

PLAY-2 PLAY-3 0.61~0.75 (0.68) 412(390 + 22) REC-1

REC-2 REC-3

CLR

TF-SET 1.57~1.71 (1.64)

QUICK M.IN

QUICK MR

VOICE 2.14~2.28 (2.21)

• Use non-locking switches that are open when off (N.O.).

• Use a shielded cable or a coaxial cable to connect the terminal and switches.

• Use resistors with a tolerance of 5% or better.

• If a function does not work with a specified resistance, increase or decrease the resistance until the voltage on the positive side of the remote control terminal is in the specified range.

• If two switches are pressed together, the result is unpredictable.

When the remote control plug is inserted, and switch 1

is closed, the voltage on the positive side of the remote control terminal becomes about 2 V, and the QUICK MR function operates. Set the value of R to suit the desired function.

Notes

1. Do not apply any voltage to the ACC3 terminal from an external source.

2. Use standard plugs (3.5 mm in diameter). If a stereo plug is used, do not use the middle (ring) terminal.

6-6-5. Linear Amplifier Control

The external control relay is not activated at the factory

so that the operation of the radio will remain at the lowest mechanical noise level during CW Full break-in operation. If the use of this control relay is required, such as for use with an external linear amplifier it may

be activated by setting the LINEAR AMP switch to ON.

12 volts at approximately 10 mA maximum is available at

pin number 7 of the REMOTE connector for control of an external keying relay, if necessary. We recommend the use of a 7 pin DIN plug for this connection. When operation of this transceiver with the TL-922/922A is anticipated you should use the control cable supplied with the linear amplifier.

Most linear amplifiers require a ground on transmit. This

is available by connecting pin 2 of the remote connector to ground. Then connect the center conductor of your

8. REFERENCE

8-1. ANTENNA INSTALLATION

■Fixed Station

For HF fixed-station operation, an antenna specifically designed for amateur operation is recommended. Antenna types include wire antennas, verticals, rotary beams, and other antenna types. (Fig. 8-1) HF antennas are quite large and must be

installed to withstand strong wind, heavy rain, etc. Any antenna used with this transceiver should be of 50-ohm impedance and should be connected using an appropriate coaxial cable such as 5D-2V (RG8/U).

Impedance matching is important. Impedance

mismatching will result in a high VSWR and power

loss, or can cause unwanted harmonic radiation and

interference (TVI, BCI). The impedance match can be checked with the SWR meter. Generally, satisfactory operation is assured when the VSWR (Voltage Standing Wave

Ratio) is less than 1.5 : 1.

A rotary beam antenna is very effective for DX communication in the 14, 21 and 28 MHz bands. (Fig. 8-2) If open wire or balanced type transmission line is used with the antenna, a suitable antenna tuner with balun is recommended between the transceiver and the feed line. Methods of construction and operating such tuners are described in detail in the ARRL Antenna Handbook, or similar publications. For operation on the 160, 75 and 40 meter bands, a simple dipole antenna, cut to resonance in the most used portion of the band, will perform satisfactorily. For operation on the 10, 15 and 20 meter bands, the efficiency of the station will be greatly increased if a good directional rotary antenna is used. Remember that even the most sophisticated transceiver is useless without a good antenna.
