Forestry Mode

Available on the TDFM-9000, Forestry Mode addresses the space installation challenges in the cockpit and airframe associated with updated USFS communications requirements.

Forestry Mode is an advanced software / hardware interface combination which allows the TDFM-9000 to operate as either 2 or 3 distinct approved Forestry radios. The USFS requires radios to have defined main and guard capabilities, by utilizing the TDFM-9000’s transceiver 4 or 6 VHF module capacity, in forestry mode, these modules are paired into Main and Guard functions. Main and guard antenna ports are switched via the newly developed ASU-9000 to a single antenna for each pairing, requiring only 3 antennas in a full 6-module installation rather than 6. Mic, Audio and PTT lines are also combined such that only 3 positions are required on the audio panel. Resulting in both significant cockpit, airframe space, and weight savings.

ASU-9000 Antenna Switching Unit

The ASU-9000 combines both the Antenna connections as well as the Audio / Mic/ PTT connections of each Main Guard paring on the TDFM-9000

By Acting as switch, the ASU limits both Antennas, and audio positions to either 2 or 3 dependent upon the configuration of the TDFM. Minimizing Antenna and Audio positions required. All while saving precious panel space.
