Radio Monitoring, the easy way. The new prime decoder!

go2MONITOR

go2MONITOR, an advanced concept for HF-VHF-UHF data protocol decoding. A smart solution including SDR control, recording, classification and decoding. Manual processing of relevant, intercepted communication is too expensive, too slow, insecure and incomplete. In this situation an automatic, flexible and expandable approach must be used at reasonable size and cost.
