The TFM-66 from Technisonic is single band VHF/FM transceiver designed to operate from 66.000 MHz to 88.000 MHz at the high end of the general service VHF low band. This transceiver tunes in 2.5 kHz steps providing for either 12.5 kHz (narrow band) or 25.0 kHz (wide band) channel spacing.

The TFM-66 features a two-channel, front panel programmable, synthesized guard receiver, 120 channels of preset memory, scan and priority scan, all available CTCSS (sub audible) tones, all DPL/DCS digital squelch codes, and it can operate without restriction on any split frequency pair available within the band.

Function control and data entry are via a front panel 12-button keypad. Operating frequency, alpha-numeric identifier and other operational data are presented on a 48-character, two-line LED matrix display.

This exceptional transceiver weighs just 3.1 pounds, is Dzus mounted and is completely self contained (no heavy remote R/T unit) eliminating problematic, costly and complicated interconnect.

The small size and light weight of the TFM-66 make it ideal for helicopter installation.
