This video show demodulation with this softeare-defined radio, including synchronous demodulator and its advantage. It gives hints for good SSB and CW copy, and an example for decoding with third party software (Wavecom's W-PC decoding HF-ACARS, namely Santa Cruz/Bolivia). An introduction into DRM reception is followed by an example in FM, and eventually fighting noise and interference with the help of "passband tuning".
