CONTROLS AND THEIR FUNCTIONS
This short description of the function of each control and jack supplies background information for
proper operation. For actual Operating Instructions, refer to
Using Your Transceiver.
MICrophone (on the side) . . .
The dynamic microphone must be connected to this jack. To Transmit,
press the button on the mic and talk into the mic. To Receive, release the button.
When transmitting, hold the microphone at an angle, 5-7.5 cm from your mouth and speak clearly in
a normal voice.
VOLUME with "ON/OFF" Switch . . .
Turn clockwise to apply power to the unit and then adjust for
the desired level of sound from the speaker. When using PA it controls the level of the PA output.
CLARIFIER . . .
Functions as a "fine tuning" (or "delta" tuning) for reception of Single Sideband
and AM signals when the Mode switch is set to either
LSB or USB.
This permits you to tune your re-
ceiver to exactly the same frequency of any other station or stations which you are communicating
with.
RF GAIN . . .
varies the sensitivity of the
RF
amplifier stages of the Receiver circuitry. For normal
operation, set
RF GAIN
to maximum and adjust
VOLUME
for a suitable listening level. Under high-
signal conditions, you may want to turn
RF GAIN
down a little and raise
VOLUME
as required.
SQUELCH . . .
Sets the level of the internal Squelch circuitry to cut out the background noise when
no signal is being received. When properly set, it allows signals to come through, but cuts off the re-
ceiver sound when no signal is being received, thus eliminating annoying background/atmospheric noise
during standby and monitoring conditions.
If set too high, you may miss some of the weaker signals. Operating conditions will determine the best
setting.
DIM ...
Controls the brightness of the Channel indicator LED. Turn clockwise to make brighter.
AM-USB-LSB Mode Switch . . .
set this switch to the desired mode of operation for both transmit and
receive. When in the AM position, both transmitter and receiver sections are operative for AM. When
set to the LSB position, the Receiver operates to receive only the lower sideband portion of a signal;
the Transmitter will transmit only the lower sideband of the modulated waveform. In the USB po-
sition, the Receiver operates only to receive the upper sideband portion of a signal; the Transmitter
will transmit only the upper sideband of the modulated waveform.
