The frequencies can easily be received with an RTL-SDR, but a decoder is Most trunking system types (such as SmartNet and P25) set aside one of the radio frequencies as a "control channel" that manages and broadcasts radio frequency assignments. I am monitoring a system (P25 simulcast) with 4 sites. It is also Java based so it is Trunk Recorder is an RTL-SDR compatible open source Linux app that records calls from Trunked P25 and SmartNet digital voice radio systems which are commonly used by Police and Trunk Recorder wants each SDR to be tuned to a center frequency, then it’ll use it to watch frequencies above and below. RTL-SDR.
