f.u.n.k.e. Avionics FSG 2T VHF/AM
Aviation Transceiver
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 to 136.975 MHz, providing 760 channels with 25 kHz channel spacing, covering a standard communications distance of ca. 100 NM (nautical miles) at FL 70.
The transceiver fits into a standard 2¼″ / 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).
Features
• VHF/AM airband transceiver• Powerful single block transceiver approved for airborne operation in fixed wing and helicopter aircraft
• 5 Watt RF output power
• Memory for 20 channels
• Integral controls enable steady performance characteristics
• Compatible with CLIMAX (multi–carrier) operation
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!
Operating Time with 12 V 7.2 Ah Battery
The following duty cycle of Transmit (TX), Receive (RX) and Standby (STBY) results in available operating time (hours). Both the worst and the most favorable operation conditions are considered, e.g. maximum receiver volume combined with maximum speaker load.
Higher current consumption will degrade the nominally available battery capability, as well as lower temperatures. The following tables show significant time differences depending on current consumption during Receive, and at temperatures.

Microphone Compatibility
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.
Equipment Required but not Supplied
• VHF aircraft antenna with coax cable RG–58 C/U and BNC connector (male)• Headphone (8… 600 Ohms, typical) and / or loudspeaker (4… 16 Ohms)
• Non–amplified dynamic microphone, (4… 600 Ohm), and/or amplified / Electret / Standard carbon microphone, with or without PTT key (separate MIC inputs amplified / non–amplified, sensitivity adjustable)
• Alternatively to b) and c) headsets with similar specifications
• Battery power supply unit 12 Vdc, minimum 7.2 Ah, for aircraft without electrical system
• Push–to–talk key, e.g. stick mounted (if microphone without PTT key is used)
• Pre–wired cable harness F10028 or F10029 (Intercom)
• 15 pole SUB–D connector type DB–15 S and cover, if no pre–wired cable harness is used.
About f.u.n.k.e. AVIONICS
f.u.n.k.e. AVIONICS was initially created in 2008 under the name Funkwerk Avionics as a company within the German Funkwerk–Group, being a result of a merger between the former Filser Electronic GmbH, Waal/Bavaria, and the aerospace business unit of Euro Telematik AG, Ulm. In 2012 Funkwerk Avionics was sold by Funkwerk, the majority of the shares was taken by a German industrial group, the current f.u.n.k.e. MITTELSTANDS GmbH. f.u.n.k.e. (fabrication, utilities, network, know–how, engineering) hereby reflects the industrial focus. As a consequence Funkwerk Avionics changed the name into f.u.n.k.e. AVIONICS at the end of 2013. Being part of an industrial group of small and medium sized enterprises, f.u.n.k.e. AVIONICS today operates two business lines, avionics products as well as avionics projects.
