Tune to à valid transmitting frequency (in the
amateur bands).
To activate the transmitter, close the PTT
switch on the microphone, and watch the ALC
indication (blue scale) on the meter. Adjust
the MIC gain control, if necessary, so that
the meter does not deflect beyond the ALC zone
(heavy blue line on the scale) on voice peaks.
You can monitor your transmitted audio by set-
ting the MONI switch on and advancing the MONI
control clockwise, but this may cause feedback
unless you are using headphones. If you have
headphones (stereo or monaural, with a 4-inch
plug), connect them to the PHONES jack now.
While monitoring your transmissions, you can
optimize the transmitter audio to your voice
using the TX SHIFT feature (yellow-labelled
switch and small control below the meter).
Press the TX SHIFT switch and adjust the con-
trol for the desired audio characteristic
while transmitting.
To use the RF speech processor:
(1) Set the METER selector to COMP.
(2) Press the PROC switch.
(3) Adjust the PROC control (second knob to
the right of the POWER switch) while
transmitting for 5 - 10dB of compres-
sion (maximum) on voice peaks, as indi-
cated on the COMP scale (beneath the
ALC scale) on the meter.
(4) Return the METER selector to ALC.
(5) Adjust the DRIVE control for meter in-
dication within the ALC zone (the MIC
gain control is inoperative while the
processor is on).
If possible, use the monitor to listen to your
transmitted audio when adjusting the PROC con-
trol (step 3 above), so you can hear the
= 23
effect of the compression adjustment (and
avoid unwanted distortion). Other stations
will hear you just as you hear yourself (if
they have a good receiver).
VOX (Voice-actuated Transmit Switching)
In any of the voice modes, you can activate
the VOX system to automatically activate the
transmitter when you speak into the micro-
phone, Press the VOX switch (next to the MOX
switch) to activate the VOX, and then adjust
the VOX GAIN control so that the transmitter
activates when you speak (without pressing the
PTT switch on the microphone). When you stop
talking the transceiver should return to
receive after a slight delay.
The DELAY adjustment on the rear panel sets
the hang time for VOX switching from transmit
to receive. The ANTI-TRIP adjustment on the
rear panel should be set so that receiver
audio from the speaker does not trip the VOX.
Clarifier (Receiver Offset Tuning)
While in contact with another station, you can
retune the receiver (if, for example, his
transmitter drifts) without changing your
transmitting frequency: while receiving, press
the CLAR key at the bottom center of the key-
pad. "CLAR! (Clarifier) will appear to the
left of the receiving frequency on the
display, and tuning will only affect the re-
ceiver.
1f you wish to view the offset of the recei-
ving frequency from the transmitter during
clarifier operation, press the OFFSET button
(the displayed offset will be preceeded by '-!
if the transmit frequency is below the recei-
ving frequency. Clarifier tuning range is
unlimited, but the offset display can only
show up to +/-9.99999 MHz.
Once the clarifier has been tuned, the new
frequency will remain in the clarifier even if
it is turned off (by pressing the CLAR key
again), as long as you remain on the same
band. In this way, the clarifier actually
serves as an auxiliary (short-term) memory.
To clear the clarifier without changing bands
you must press the AC (0) key t w i c e .
Remember to press the CLAR key again to return
the receiver to the transmitting frequency
"when your QSO is finished.
