Analog Airborne FM


The Technisonic TFM-566 is a dual band , frequency agile airborne FM transceiver designed to provide radio communications on every available channel in the VHF General Service Hi Band (138 to 174 MHz) and enable communications in the International VHF Lo Band (66 to 88 MHz).

This transceiver is able to tune in 2.5 kHz steps providing both 12.5 kHz (narrowband) or 25.0 kHz (wideband) operation in both bands. Additionally, the TFM-566 features a 2 channel, synthesized VHF high band guard receiver. This transceiver can be operated as a single radio (one band at a time) occupying a single audio controller position or it can be installed in “dual mode” to two audio controller positions (typically FM1 and FM2) allowing for simultaneous operation in both bands. The TFM-566 can also act as a cross-band repeater and offers 400 memory positions (200 per band) each of which is capable of storing a transmit frequency, a receive frequency, a separate CTCSS tone and/or DPL/DCS digital squelch code for each transmit and receive frequency, and a nine-character alpha-numeric identifier for each channel. All data and software control functions are via the front panel 12-button keypad. Operating frequency, alpha-numeric identifier and other related data are presented on a 96-character, four-line LED matrix display. The small size and light weight of the TFM-566 make it ideal for helicopter installation.

NOTE: The TFM-566 is not FCC or IC approved and is therefore not available for use in North America.
