Demod: SDR Receiver
Listen to network SDR receivers with live tuning, recording and on-device decoding.
Useful for radio hobbyists who already have access to an SDR server
Waterfall controls, multiple receiver protocols and replay put listening tools on a phone.
Keep in mind: An SDR server and network access are required; beta decoders and reception quality cannot guarantee readable signals.
