MIC PROC Knobs
MIC Knob
The inner
MIC knob adjusts the microphone input
level for (non-processed) SSB transmission.
Advice
If you adjust the MIC Gain while speaking in a louder-
than-normal voice level and watching the ALC level
on the right-side meter, adjust the MIC Gain so that
the ALC reaches over to the right edge of the ALC
scale. Then, when you speak in a more normal voice
level, you’ll be certain not to be over-driving the mic
amplifier stage.
PROC Knob
The outer
PROC knob sets the compression (input)
level of the transmitter RF speech processor in the
SSB and modes, when activated by the button with
the same name (see next section).
PROC (Processor) Switch
This button enables the RF speech processor for SSB
transmission. Processing level is set by the outer con-
trol with the same name (see previous section). While
activated, the LED in this button glows red.
Advice
The Speech Processor is a tool for increasing the av-
erage power output through a compression technique.
However, if the PROC level control is advanced too
far, the increase in compression becomes counter-pro-
ductive, as intelligibility will suffer. We recommend
that you monitor the sound of your signal using the
Monitor (with headphones), and watch the Oscillo-
scope page on the TFT while transmitting (Monitor
must be on), then advance the PROC level only as far
as required to obtain a useful increase in average power
output.
VOX DELAY Knobs
VOX Knob
The inner VOX knob sets the gain of the VOX cir-
cuit, to set the level of microphone audio needed to
activate the transmitter during voice operation while
the VOX button is engaged. The VOX switch
(# above) must be switched On to engage the VOX
circuit.
DELAY Knob
The outer DELAY knob sets the hang time of the
VOX circuit, between the moment you stop speaking,
and the automatic switch from transmit back to re-
ceive. Adjust this for smooth VOX operation, so the
receiver is only activated when your transmission is
ended and you wish to receive.
For CW operation, you can adjust the keying delay
separately; see control # below.
KEYER Switch
This button toggles the internal CW keyer on and off.
While activated, the LED in this button glows red. The
Keyer sending speed, and the CW Hang Time are ad-
justed via the controls described in the next section.
SPEED CW DELAY Knobs
The internal Electronic Keyer is activated by the
KEYER switch, described in the previous section.
SPEED Knob
The inner SPEED knob adjusts the keying speed of
the internal CW keyer. Clockwise rotation increases
the sending speed.
CW DELAY Knob
This outer CW DELAY knob sets the hang time of
the CW “VOX” circuit, between the moment you stop
sending, and the automatic switch from transmit back
to receive during “Semi-break-in” operation. Adjust
this just long enough to prevent the receiver from be-
ing restored during word spaces at your preferred send-
ing speed. Clockwise rotation increases the hang time.
Note
The SSB VOX hang time is adjusted via the DE-
LAY control described in section above.
BK-IN/SPOT Switches
This button turns the full break-in (QSK) CW capa-
bility on and off. While QSK is activated, the LED in
this button glows red.
The SPOT button turns on the CW receiver spot-
ting tone; by matching the SPOT tone to that of the
incoming CW signal (precisely the same pitch), you
will be “zero beating” your transmitted signal on to
the frequency of the other station.
NB/SQL Knobs
NB Knob
The inner NB knob adjusts the noise blanking level
when the (analog) IF noise blanker is activated by press-
ing the NB button. The Noise Blanker is activated
via the NB switch, described in the next section.
SQL Knob
The outer SQL knob sets the signal level threshold
at which main (VFO-A) receiver audio is muted, in
all modes. It is very useful during local rag-chews, to
eliminate noise between incoming transmissions. This
control is normally kept fully counter-clockwise (off),
except when scanning and during FM operation.
