Kenwood TS-930S Instruction Manual page 23

In CW mode, sidetone output is controlled by the
MONITOR switch.
Note:
The frequency display indicates transmit carrier frequency.
KEY jack
When using an electric keyer,
check the polarity.
The KEY jack provides
approx. +10 V DC.

3. RTTY
RTTY operation requires a demodulator and a teletype-
writer. A demodulator including 2,125 and 2,295 Hz
(170 Hz shift) filters will be acceptable and may be con-
nected directly to the PHONE PATCH OUT jack. To use the
transceiver's FSK circuit with older high voltage teletype
equipment, use a keying relay in the teletypewriter closed
loop and connect the relay contacts to the rear-panel RTTY
KEY jack.
Figure 5-8 shows the frequencies relationship between
reception and transmission with the TS-930S.
In FSK operation, the space frequency is indicated on the
frequency display.

4. FSK transmission
1. Connect an FSK generator or RTTY terminal unit
output to the rear-panel FSK KEY jack (9).
2. Place the MODE switch (51) to FSK.
3. Place the standby switch (45) to SEND.
4. Place the METER switch (2) to ALC.
5. Adjust the PROCESSOR-OUT control (41) for an
on-scale ALC reading.
6. To receive connect the PHONE PATCH output to
the demodulator input terminal.
© Operation
Place the MODE switch to FSK.
— CAUTION
When transmission is greater than 15 minutes continuous
in the FSK mode, reduce the RF power to approximately
50 W by adjusting the SPEECH PROCESSOR control. In
this condition, the ALC does not function. If the output
power changes, re-adjust with PROCESSOR-OUT control.
5. AM transmission
Setting the MODE switch to AM allows AM transmission.
To adjust carrier, adjust the CAR control so the power
meter reading is approx. within 15~ 20 W.
Speak into the microphone and adjust the MIC volume control
so the ALC meter deflects a little at the peak voice level. Note
that the ALC full scale reading results in distortion.
6. SPEECH PROCESSOR
In SSB operation (particularly DX operation), it may be
desirable to increase ''talk-power'' by using the speech
processor. This -may make the difference between a
marginal, and a copiable signal.
e Operation
The speech processor system in the TS-930S is an RF clip-
per using two filters.
Turn the PROCESS switch ON and place the METER switch
to COMP. Adjust the PROCESSOR IN control while speak-
ing 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
