Project 25 Airborne FM – Outdated

Project 25 or P25 is  a common set of digital protocols that when implemented, would support interoperability across radio manufacturers,  Today P25 is the standard public safety radio protocol endorsed by the US. Department of Homeland Security and every major US radio manufacturer. Today’s mission based aircraft operate all across the P25 spectrum, whether you are talking across the county or across the state, P25 capability is required.

The TDFM- 9000 / 9200 / 9300 series radios and the TDFM-9100  radio offer Project 25 Analog/Digital/Encrypted/Multi-band AM/ FM radio transceivers capable of meeting your most demanding operating requirements in both Phase I (FDMA) and Phase II (TDMA) modes. The TDFM-9000 series consists of multiple models which are configurable to meet each user’s specific requirement. Each TDFM-9000/9200/9300 is a 4.5″ high Dzus panel mount radio and is completely self-contained (no remote mount box).

The TDFM-9000 can support up to six P25 (Phase I and Phase II compliant) All-Band RF modules. There is no restriction on the number of like modules that can be installed. For example, if your requirement is for three (or even more) 700/800 MHz modules operating at the same time, then the TDFM-9000 will work for you.

The TDFM-9200 can support up to two P25 (Phase I and Phase II compliant) All-Band RF modules, and two (2) Technisonic Analog modules. There is no restriction on the band mix of P25 modules modules, or options that can be installed. For example, if your requirement is for two VHF/ 700-800 MHz modules operating at the same time, along with Low-band 30-50 and Air-band 118-136AM then the TDFM-9200 is the right radio for your mission..

The TDFM-9300 can support up to four P25 (Phase I and Phase II compliant) All-Band  RF modules, and one Technisonic analog module. There is no restriction on the number of like P25 modules that can be installed. For example, if your requirement is for three (or even more) 7-800 MHz modules operating at the same time, then the TDFM-9300 will work for you.

The TDFM-9100 is an All-Band capable airborne radio which operates in the same manner as the TDFM-9000.  Able to support one or two P25 Phase II modules with any available option(s), it is ideal for those users who need only one or two P25 compliant  modules. Its small size (3″ height) and light weight make it ideal for helicopter installations.

The TDFM-136B transceiver is the radio of choice for forestry operations,  capable of analog and digital communications on every available channel in the VHF High Band (136 to 174 MHz). It is 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  are available and can be programmed from the front panel. The TDFM-136B can display channel, nomenclature, and operating frequency for both main and guard channel simultaneously.
