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


go2MONITOR, an advanced concept for HF-VHF-UHF data protocol decoding. A smart solution with SDR control, multi channel signal detection, classification, recognition, recording, demodulation and decoding. Manual processing of relevant intercepted communication is too expensive, slow, insecure and incomplete. In this situation an automatic, flexible and extensible approach must be used, with reasonable scope and costs.
