9 SPECIALIZED COMMUNICATIONS

SLOW SCAN TV/ FACSIMILE

Slow-scan Television (SSTV) is a popular application for transmitting still images over the air, from one station to another. Instead of trying to describe your station, simply showing it is much faster. Transmitting images over the air requires a scan converter, besides a transceiver. A scan converter transforms images taken with a video camera into audio signals that can be fed into your transceiver. The recipient’s scan converter transforms audio signals back into video images so that he or she can view them on a TV set.

Nowadays instead of a scan converter, many hams use a personal computer, a software application, and an interface attached to the transceiver. This is much cheaper, more flexible, and does not require a TV set. In recent years, many low cost digital cameras have become available. You can transfer images from these cameras into your computer.

For further information, consult reference books about Amateur Radio. The frequencies (measured in kHz) commonly used for SSTV operation are listed below:

Fax (facsimile) is one of the original image transmission modes. Using this mode allows you to exchange more detailed graphics than SSTV. Amateur Radio fax functions much like old analog fax systems. It scans paper and converts acquired image data into a series of tones representing white and black portions of the image. Because fax requires longer transmission time, you should use it only when band conditions are stable with strong signals.

Popular fax frequencies include the following:

• 7245, 14245, 21345 (International Net), and 28945 kHz

Operating on SSTV or fax mainly involves learning the functionality of your computer application or accessory hardware that supports these modes. Consult the instruction manual 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.

REJECTING INTERFERENCE

IF FILTER

The IF filters are designed for selecting the exact range of intermediate frequencies that are sent to the next stage in the receive circuit. Interference adjacent to the desired signal can be reduced by selecting a narrow bandwidth filter and/ or shifting the center frequency of the filter.

To more effectively remove interference, combine the IF filtering and the DSP filtering (AF) described on pages 46 and 47.

CHANGING THE IF FILTER BANDWIDTH

When adjacent frequency interference is present at both sides of the desired signal, narrowing IF filter bandwidth may be the best way to remove the interference. Changing the filter bandwidth will not effect the current reception frequency.

You can install 2 optional IF filters for SSB, CW, and FSK modes. After installing the optional filters {page 83}, the transceiver automatically recognizes what type of optional filters are installed.

■ SSB/ AM

When you operate the transceiver in SSB or AM mode, you can manually select the wide or narrow filter.

Press [FIL/ NAR] (1 s) to select another IF filter.

• Each press of [FIL/ NAR] (1 s) changes “ ” (Normal) / “NAR”, then back to “ ” (Normal).

• If Menu No. 17 is ON (default is OFF) and 2 IF filters have been installed, you can select secondary IF filter. In this case, each press of

[FIL/ NAR] (1 s) changes “ ” (Normal) / “NAR” / “NAR 2”, then back to “ ” (Normal).

■ FM

In FM mode, you cannot change the reception IF filter bandwidth. The bandwidth is fixed at 12 kHz.

IF SHIFT (SSB/ CW/ FSK)

Shifting the center frequency of the filter pass band is an additional method of removing adjacent frequency interference. Shifting this center frequency does not change the current reception frequency.

To remove interference that is higher in frequency than the desired signal, turn the IF SHIFT control counterclockwise. To remove interference that is lower in frequency than the desired signal, turn the IF SHIFT control clockwise.

DSP FILTERS

KENWOOD digital signal processing (DSP) technology is adapted to this transceiver. Using DSP filtering (AF), you can control the bandwidth, cancel the multiple jamming beat, and reduce the noise level using DSP filtering technology.

CHANGING THE DSP FILTER BANDWIDTH

For improving interference reduction capability, this transceiver also provides the DSP filtering (AF) along with IF filters. When in SSB, FM, or AM mode, you can change the filter bandwidth by altering its low and/ or high cut-off frequency. For CW and FSK modes, you can change the filter bandwidth by directly specifying a bandwidth. Changing the DSP filter bandwidth (AF) does not affect the current reception frequency.

■ SSB/ FM/ AM

Note:

◆

The cut-off frequencies (LO) can be adjusted independently for each operating mode. When you change the operating mode, the previous setting is recalled for each operating mode.

◆

When the DSP filter for data communication (Menu No. 45) is ON, you cannot change the DSP filter bandwidth. Select “oFF” to adjust the DSP filter bandwidth.

NOISE BLANKER

Noise Blanker was designed to reduce pulse noise such as that generated by automobile ignitions. Noise Blanker does not function in FM mode.

Press [NB/T/ 7] to toggle the Noise Blanker ON and OFF.

• “NB” appears when the function is ON.

You can further adjust the Noise Blanker level from 1 to 10. The default level is 6.

Press [NB/T/ 7] (1 s), then turn the MULTI control to adjust the Noise Blanker level.

• “NB LV.” and the current level appear on the subdisplay.

Note:

Noise Blanker is available only for SSB, CW, FSK, and AM

modes.

DIGITAL NOISE LIMITER (DNL)

Digital Noise Limiter (DNL) is designed to reduce pulse noise such as that generated by automobile ignitions. Try this function when the Noise Blanker function cannot remove the pulse noises effectively. Digital Noise Limiter does not function in FM mode.

Press [DNL] to toggle the DNL ON and OFF.

• “DNL” appears when the function is ON.

■ Setting the NR1 Level Adjustment

The NR1 (Line Enhanced Method) uses an adaptive filter to reduce the noise element from the received signals. When the S/N ratio is reasonably good in SSB, using the NR1 will improve the S/N further.

While NR1 is ON, you can further adjust the noise reduction level by pressing [NR] (1 s), then turn the MULTI control to select the level from 1 to 9 or AUTO. The default is AUTO.

■ Setting the NR2 Time Constant

You can change the correlation time for NR2 (SPAC). When in SSB mode, select the correlation time that allows you to hear signals with clarity. When receiving CW, it is best to select the longest correlation time that allows reliable reception. The longer the correlation time, the better the S/N ratio.

When NR2 is ON, press [NR] (1 s), then turn the MULTI control to select the correlation time from 2 ms to 20 ms. The default is 20 ms.

Note:

Using Noise Reduction 2 in SSB mode may lower the clarity of signals or induce pulse noise, depending on the conditions.

You can further adjust the DNL level from 1 to 3. The default level is 2.

Press [DNL] (1 s), then turn the MULTI control to adjust the Digital Noise Limiter level.

• The current level appear on the sub-display.

Note:

◆

Digital Noise Limiter is available only for SSB, CW, FSK, and AM modes.

◆

Depending on a pulse type, the DNL function may not be able to remove the noise.

◆

Turning the DNL function ON when there is no pulse-type noise and the signal is relatively strong, it could degrade the signal readabilty .

◆

When the DNL function is ON, the high-cut filter frequency becomes 3.0 kHz regardless of the DSP filter settings.

◆

The DNL function can be used with the Beat Cancel (BC), Noise Reduction (NR) , and Noise Blanker functions at the same time.

QUICK MEMORY

Quick memory is designed to quickly and temporarily save data without specifying a particular memory channel. Use Quick memory to store data you will not use in 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. You can quickly jump between several different memory channels as you monitor them.

This transceiver provides 10 Quick memory channels (“0_” to “9_”) that can store the following data:

STORING INTO QUICK MEMORY

Each time you store a new frequency, all previously stored frequencies are bumped to the next respective Quick memory channel. When all 10 memory channels contain frequencies, storing one more frequency bumps the contents of memory channel 9 off the stack (the data is lost).

The following diagram illustrates how the Quick Memory stacks the data in memory each time you press [QMI/ M.IN].

NORMAL SCAN

When you are operating the transceiver in VFO mode, 2 types of scanning are available.

• VFO Scan The transceiver scans the entire frequency range

of the transceiver. For example, if you are operating and receiving on the transceiver’s VFO A at 14.195.00 MHz, it scans entire frequencies in the range of 30.00 kHz to 59.999.99 MHz. (Refer to available VFO frequency range in the Specifications.)

• Program Scan By programming the start and end frequency in

Memory channels 90 ~ 99 {page 53}, you can limit the scanning frequency range. Since there are 10 memory channels (90 ~ 99) available for specifying the start and end frequency, you can select one or more (a maximum of 10) ranges to scan. This is useful when you are waiting for a DX station on a certain frequency but the station may appear on a slightly higher or lower frequency.

VFO SCAN

VFO Scan scans the entire frequency range that is available for the current VFO. When the Program Scan frequency range is not programmed or no Scan Group is selected for the Program Scan, the transceiver also scans the entire frequency range available for the current VFO.

The memory channel numbers 90 ~ 99 have alias names, “VGROUP”. “VGROUP–0” represents channel 90, “VGROUP–1” represents channel 91, “VGROUP–2” represents channel 92, and so on up to “VGROUP–9” which represents channel 99.

If one or more Program Scan frequency ranges are programmed in VGROUP–0 to 9 (Memory channel numbers 90 ~ 99 in other words):

1 Press [SCAN/ SG.SEL] (1 s) in VFO mode.

• “VGROUP -- n” (where n represents a VGROUP number from 0 to 9) appears on the sub-display.

2 Turn the MULTI control to select the Program

Scan memory (VGROUP–0 to VGROUP–9). As you select the channel, “on” or “oFF” appears on the frequency display. “on” signifies that the selected VGROUP is active for the program scan and “oFF” signifies that the selected VGROUP is inactive for the Program Scan.

Configure all VGROUP channels (VGROUP–0 ~ VGROUP–9) as “oFF” by pressing [ ].

3 Press [SCAN/ SG.SEL] or [MTR/ CLR] to return

to the current VFO mode.

4 Press [SCAN/ SG.SEL] to start the VFO Scan. 5 Press [SCAN/ SG.SEL] or [MTR/ CLR] to stop the

VFO Scan.

Note:

◆

While scanning, you can change the scan speed by turning the

RIT/ XIT

control. Turn the control clockwise/ counterclockwise to decrease/ increase the scan speed. The speed indicator appears on the sub-display, where P1 is the fastest speed and P9 is the slowest.

◆

You cannot change the VFO Scan speed in FM mode.

PROGRAM SCAN

Program Scan monitors the range between the start and end frequencies that you have stored in Memory channels 90 ~ 99 (VGROUP–0 ~ 9). Refer to “STORING FREQUENCY RANGES” {page 53} for details on how to store the start and end frequencies to Memory channels 90 ~ 99 (VGROUP–0 ~ 9).

You can select a maximum of 10 memory channels (VGROUP 0 to 9) and sequentially scan the frequency ranges that you stored in these channels. If the current VFO frequency falls within the selected VGROUP frequency range, the Program Scan starts from the VGROUP number and then continues to scan the next larger VGROUP number. If the current VFO frequency is outside all of the VGROUP frequency ranges, the Program Scan starts from the smallest VGROUP number that is selected as “on” (each VGROUP can be set to either “on” or “oFF”).

1 Press [A/B / M/V] to select VFO A or VFO B. 2 Press [SCAN/ SG.SEL] (1 s).

3 Turn the MULTI control or press Mic [UP]/ [DWN]

to select the memory channel (VGROUP–0 to

12 SCAN

VGROUP–9). As you select the Memory Channel, “on” or “oFF” appears on the main frequency display. “on” signifies that the memory channel is active for the program scan and “oFF” signifies that the memory channel group is inactive for the program scan.

4 To activate the Program scan frequency range,

select the desired VGROUP number by turning the MULTI control. Then, press [ ] to select “on” for the VGROUP (channel). When a channel is activated for the Program Scan, “on” appears on the display.

Note:

At least one of the valid Program Scan channels (from 90 to

99) must be programmed and selected to perform the Program Scan. If no VGROUP (memory channel 90 ~ 99) is selected for the Program Scan, the transceiver performs the VFO Scan {above}.

5 Press [SCAN/ SG.SEL] or [MTR/ CLR] to return

to the current VFO mode.

6 Press [SCAN/ SG.SEL] to start the Program

Scan.

• To quickly move towards a desired frequency while scanning, turn the Tuning control or the MULTI control, or press Mic [UP]/ [DWN].

• Turning the RIT/ XIT control clockwise decreases the scan speed and counterclockwise increases the speed, except while in FM mode. The current scan speed is shown on the display; P1 is the fastest speed and P9 is the slowest.

• While in FM mode, Scan automatically stops on a frequency where a signal is present. The transceiver will either remain on that channel for a short time (Time-Operated mode) or until the signal drops out (Carrier-Operated mode), depending on which mode you select via Menu No. 11 {page 58}.

7 To stop Scan, press [SCAN/ SG.SEL] or

[MTR/ CLR].

Note:

◆

If you have turned the squelch threshold while in FM mode, Scan may fail to stop at a channel where a signal is present. If this happens, turn the control slightly counterclockwise.

◆

If you press for memory channels 90 to 99, the transceiver starts VFO scan.

◆

When the current receive frequency is within one of the ranges that you selected with channel numbers, Scan starts with the current frequency. The operating mode stored in the memory channel is used.

◆

The operating mode can be changed while scanning, but the memory channel is overwritten with the changed mode.

◆

When the current Scan range is smaller than a single step of the

MULTI

to the start frequency, and counterclockwise to the end frequency.

◆

Starting Program Scan switches OFF the RIT and XIT functions.

PROGRAM SCAN PARTIALLY SLOWED

You can specify a maximum of 5 frequency points for each memory channel from 90 to 99 so that the Program Scan slows down the scanning speed. To specify the slow down frequency points, first program the start and end frequencies into a memory channel (90 ~ 99) {page 53}.

1 Access Menu No. 08 to confirm that the function is

ON (default is ON).

2 You can further configure the slow down frequency

width. Access Menu No. 09 to select the range from 100 Hz to 500 Hz (default is 300 Hz).

Note:

If you select, for example, 500 Hz for Menu No. 09, the Program Scan slows down to a ±500 Hz width, centering the frequency you marked below.

3 Press [A/B / V/M] (1 s) and turn the MULTI control

to recall the memory channel (90 ~ 99) for which you want to specify the scan slow down frequencies.

4 Press [ ]/ [ ] to confirm the start ([ ]) or end

([ ]) frequency.

5 Turn the Tuning control to the center frequency

point that you want the Program Scan to slow down. Press [QMI/ M.IN] to mark the Slow down frequency point. The “ ” icon appears.

6 Repeat step 5 to specify the center slow down

frequency points. You can specify a maximum of 5 frequency points for each channel.

7 If you want to clear a slow down frequency point

that you previously stored, select the frequency that you stored. Press [QMI/ M.IN] at this frequency spot where “ ” appears.

• A confirmation beep sounds and the

transceiver “ ” disappears.

• If you want to clear all the slow down frequency

points at once, perform the Channel \ Channel Transfer to overwrite the memory data to the same memory channel {page 52}. This operation removes all the frequency points that you stored.

8 Press [A/B / M/V] to return to VFO mode. 9 Press [SCAN/ SG.SEL] to start the Program Scan

MEMORY SCAN

Memory Scan monitors all memory channels in which you have stored frequencies (All-channel Scan) or only a desired group of memory channels (Group Scan).

Scan automatically stops at a channel where a signal is present, regardless of the operating mode. The transceiver will either remain on that channel for a short time (Time-Operated mode) or until the signal drops out (Carrier-Operated mode). Use Menu No. 11 to select the mode. The default is “to” (TimeOperated).

SCAN RESUME METHOD

The transceiver stops scanning at the frequency (or memory channel) where a signal is detected. It then continues scanning according to which resume mode you have selected. You can choose one of the following modes. The default is Time-operated mode.

• Time-Operated mode (“to”)

The transceiver remains on a busy frequency (or memory channel) for approximately 6 seconds, then continues to scan, even if the signal is still present.

• Carrier-Operated mode (“co”)

The transceiver remains on the busy frequency (or memory channel) until the signal drops out. There is a 2 second delay between signal dropout and scan resumption.
