Digital FM Transceivers
P25 Digital FM transceivers are now being required by numerous forestry departments and customers.
The digital technology is far superior to the analog FM systems, providing a more robust and reliable communication system. Skye Avionics is able to offer sales and servicing of Technisonic and Cobham (formerly NAT) P25 digital FM transceivers.
The digital transceivers are capable of analog and digital communications on every available channel in the General Service VHF High Band (136 to 174 MHz). They are also capable of multi mode operation in the 25 KHz analog, 12.5 KHz analog, and Project 25 12.5 KHz modulation on a channel by channel basis. All features (including operating frequency) are available and can be programmed from the front panel of either the technisonic or cobham transceivers. The TDFM-136B and NPX-136D-070 can display channel, nomenclature and operating frequency for both main and guard channel simultaneously.
A major benefit of the TDFM-136B is that it is pin compatible with legacy TFM-138B transceivers, making the change to a P25 compliant digital fm cost effective and a simple installation.
