Trunking Recorder

Trunking Recorder is a Windows application for recording/importing audio from trunked radio systems monitored by Unitrunker, SDRTrunk or ProScan. Trunking Recorder will save all the recorded calls and allows searching and playback through a web browser. Trunking Recorder will also queue up recorded calls so you never miss any activity when multiple talkgroups are active at the same time.
