VHF/AM RADIO FSG 2T
5 Functional Description
52 FAV_D10048 June 2014
SQ (SQUELCH)
Rotary control (outer ring)
After turning ON the radio FSG 2T the automatic squelch is active
depending on the SQ knob position.
 Standard Operating Mode: Set the SQ knob to the dot position, the
Squelch (mute) threshold is approximately 1 µV. No Receiver noise
should be audible during Standby. Only received signals above the SQ
threshold are audible.
 Rotating the SQ knob fully counter-clockwise (ccw) puts the radio into
the SQ-OFF mode (overrides the automatic squelch). Basic receiving
noise is then audible during Standby. This adjustment gives maximum
receiving range. Slightly increased current consumption.
 Rotating the SQ knob clockwise (cw) achieves Receiver muting.
 To eliminate ignition noise or RF interference adjust the SQ knob up to
the full clockwise (cw) position. This gradually increases the required
RF signal to exceed the SQ threshold (max. threshold 5 µV / -93 dBm).
F/CH Button
Push button
When pressing the F/CH button
 while in DIRECT TUNE MODE (MHz or kHz is underscored), this will
change the radio into CHANNEL MODE, or
 while in CHANNEL MODE (Channel number is underscored), this will
change the radio into DIRECT TUNE MODE.
TX/RX LED
The TX/RX 3-color Status LED on the front panel indicates the following:
CLEAR ................... indicates a Standby condition or radio is OFF.
STEADY RED .......... indicates a Transmit condition without or too low
modulation.
FLICKERING
YELLOW ................ indicates a Transmit condition with proper
microphone signal / modulation.
STEADY
YELLOW ................ indicates a Transmit condition with too much
modulation or background noise (microphone sensitivity
too high)
STEADY GREEN ...... indicates a Receive condition; Squelch is open
automatically (or set OFF manually).
STEADY GREEN ...... indicates a sufficient microphone level while in the
Intercom condition
