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.

SSTV FREQUENCIES

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.

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.

3 Select the ALC meter function by pressing [METER].

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.
