P25 Information 

What is P25?:

P25 is the interoperable Digital Radio communications standard for Public Safety in the United States and several other countries. 

P25 Phase 1 Conventional as we use utilizes FDMA modulation and allows digitized voice or data.  Digital (Numeric/Hex) IDs and signalling are sent along with the digital voice signal.  There are several systems that allow linking of P25 repeaters.

Programming Information to Access the Repeaters

We currently have P25-Enabled Repeaters on the following frequencies:

147.150 TX / 147.750 RX
444.000 TX / 449.000 RX
927.025 TX / 902.025 RX

All P25-Enabled repeaters are setup as Mixed-Mode Analog/P25 and use the following access parameters:


Analog PL: 123.0
P25 NAC: 293

NOTICE: The repeaters are currently in stand-alone mode due to changes made to the P25NX network.  We are currently deciding if we are going to try to re-join this network, move to MMDVM/Quantar Link, or another alternative network.

P25NX V1 Conventional Talk Groups

All of our P25-Capable systems utilize a mix of Motorola Quantar and GTR8000 repeaters, AstroTac Comparators, and DIU3000 Digital Interface Units.
