The P25 standard does not address any operational or interoperability needs the standard does not provide a fire department with interoperability unless it is planned for.Ī lone agency on P25 is no more interoperable than being on a UHF system trying to interoperate with a department on VHF. The P25 standard continues to provide direction for radio manufacturers and users as communication technologies become integrated systems that enable a smartphone to operate like a two-way radio and vice versa is one example. Prior to the P25 standard, each manufacturer had proprietary digital radios that could interoperate only with like radios. The hope was that this would introduce competition into the market and help control costs. Their goal was to create a standard enabling different radio manufacturers to build equipment that could operate together. The guide has a somewhat handheld-radio perspective, however the guiding principles are very much the same for planning and purchasing in-cab radios.įor the uninitiated, the Association of Public-Safety Communications Officers developed the APCO P25 standard APCO representing the public safety technical community and the Telecommunications Industry Association. Based upon the Technisonic TDFM 9100 Series P25 FM.The IAFC guide, produced with input and insights from fire service experts, shows how to assemble a work committee to conducting a needs assessment as well as implementation and personnel training. Even today, interoperability between different first responder agencies is not a given - which is why the Technisonic cross-band radio solution being offered by Texas' Dallas Avionics is worthy of note. Years after 9/11, first responders still remember the coordination problems they experienced due to a lack of interoperable radio communications. Dallas Avionics Enables Cross-Band Communications During the safety seminar, Dallas Avionics will discuss the latest Technisonic, Jupiter Avionics, AEM, Laserdyne, Power Sonix, and RockAIR equipment. All attendees from the APSA safety seminar are welcome to attend. Dallas Avionics Supports Continuing Education at APSA Safety Seminar This highly sensitive and selective receiver offers identical perf.

The Technisonic TSR-4100 receiver is a single channel remote mount, fully synthesized, 19' rack-mount, VHF/AM stand alone component which operates over the frequency range of 117.975 MHz to 138.000 MHz, with 25 KHz channel spacing.
