2.2 General Description
The FSG 2T VHF/AM COM is a miniaturized, lightweight, panel mounted (also for
helicopters no shockmounts are required), single block transceiver operating in the
VHF/AM airband radio frequency range 118.000 MHz ... 136.975 MHz, thus providing
760 channels with 25 kHz channel spacing, covering a standard communications
distance of ca. 100 NM (nautical miles) at FL 70.
2.2.1 Application
The equipment is approved for airborne operation as COM 1, COM 2, COM 3 in Fixed
Wing and Helicopter aircraft, and for ground use in any Portable, Fixed Based or Mobile
operation.
Ultra low power consumption in conjunction with extremely wide DC supply voltage
range, small dimensions and wide scope of accessories allow universal airborne
applications in any powered aircraft, motor glider and Ultralight, and in glider and
balloon, for primary or (also battery supplied) backup operation.
Universal use in ground vehicle, as well as for compact portable cases and for desk-top
or rack mounted, local or remote controlled, fixed base primary, or (also battery supplied)
backup operations, are further applications. Please always ensure suitable antenna
solutions!
2.2.2 Operation Description
The transceiver fits into a standard 2¼ in. / 58 mm diameter instrument hole and is fixed
by four (4) screws M4. Installation depth behind the front panel including connectors and
wiring is 240 mm.
Connections on the rear panel to the electrical environment are achieved via a locked
Standard DB-15 male connector using a wiring harness, and a BNC antenna connector.
All operational control and display elements are located on the night-design front panel:
Transmit / Receive Mode, modulation level or Intercom is indicated by a 3-color Status
signaling LED on the front panel.
The back-lit Liquid Crystal Display (LCD) shows the active frequency, onboard supply or
memory channel number as well as ERROR codes (if applicable). During switch-on the
firmware version is shown and a display check is performed.
For airborne and ground application two display modes are user selectable:
