VOX GAIN CONTROL
VOX
GAIN DELAY
This control varies the threshold level of the noise blanker. Adjust
the control to remove noise from the desired signal.
This control varies the gain of the RF stage when the transceiver is
in the receive mode. Slide the control upwards for maximum gain.
Note that as the control slides downwards, the "S" meter needle
rises, and only those signals stronger than the level indicated by the
needle will be heard. In the FM mode, regardless of the control
setting, the RF gain is fixed at the maximum.
This control varies the RF output power from 10 watts to maximum
(SSB:100 watts
PEP, CW/FM:100 watts, AM:40 watts). Slide the
control upwards to increase the output power.
This control increases and decreases the sensitivity of the VOX
circuit. When operating in the CW mode, semi break-in or full break-
in operation is possible.
©MIC GAIN CONTROL
When operating in the SSB, AM or FM mode, adjust the control so
that the circuit activates with a normal speech level. See page 30 for
more information.
This control changes the transmit to receive switching time. Adjust
it such that transmit to receive switching does not occur during
pauses in normal speech.
For CW operation, adjustment depends on the keying speed used.
Adjust this control for a suitable modulation level while speaking
into the microphone in a normal voice. Slide the control upwards to
increase the gain while monitoring the front panel ALC meter. Set
the control so the meter needle just begins to move within the ALC
zone.
This control also varies the speed of the electronic keyer when this
feature is used.
