Trunker
From Wikipedia, the free encyclopedia
Trunker is software for the IBM-PC to decode and monitor Motorola based trunked radio control channels.
The software started as a semi-anonymous post to Usenet in February of 1997. An updated version was released in July 1997 which led to over 9 years of development of the software. A working EDACS decoder also appeared as a Usenet posting in December of 1997. Development continues with new enhanced versions including versions for EDACS and native Windows based applications. Additionally new formats like LTR, MPT1327 and APCO P25 system support have been added.
With this software users can find and track talkgroups, users by radio IDs, find where users switch to when they switch to another talkgroup, and find ALL the frequencies for the system from just one control channel!
The software is for the advanced user as it requires modifying your radio receiver to "tap" into the baseband audio of the radio to get the raw data to an external serial port demodulator.
