VHF/AM RADIO FSG 2T
2 General Description
12 FAV_D10048 June 2014
FREQUENCY MODE: Active Frequency and actual onboard voltage are shown on
the display. Turning / pushing the F/CH knob changes Frequency.
CHANNEL MODE: Active Channel Number (1 … 20) and associated Frequency
are shown on the display. Turning the F/CH knob changes preset
Channel Number and associated Frequency. Reprogramming
without restriction.
Only for ground based operation:
Optionally a particular mode can be set where the operation is
limited to use only preset channels. To set this mode the radio has
to be opened. This may only be performed by an approved
repair facility!
20 preset memory channels and the last operating setting remain all stored in a non-
volatile memory. Switching OFF or power failure does not result in loss of memory
information.
Turning the left inner knob adjusts loudspeaker or headset audio level. Full ccw position
turns the radio OFF.
The continuously variable SQ-knob (left, outer ring) adjusts the Squelch threshold. Full
ccw position turns the SQ circuit OFF (full Receiver sensitivity, continuous RX noise is
audible during RX Mode).
On the rear panel a 15-pin SUB-D connector for the aircraft wiring is located. It contains
two independent microphone inputs which can be set individually by (covered) DIL
switches suitable either for
Dynamic non-amplified microphones,
Amplified Dynamic / Electret / Standard Carbon Microphones, with or without DC
supply, or
one input for a Dynamic non-amplified microphone and the other input for an
Amplified Dynamic / Electret / Standard Carbon Microphone.
For each MIC input, the microphone signal can be adjusted by potentiometer #1 and #2
to modulate the transceiver properly. Additionally, supply current for amplified or
Standard Carbon Microphones for each MIC input can be set by DIL switches to 2 mA,
8 mA, 10 mA, or none.
Phone audio output is adjustable by potentiometer #3 on the rear panel.
For two seat aircraft and noisy environment, the voice activated (VOX) Intercom is a long
expected feature. It eliminates constant background noise since it is only active when
you talk.
