Hi all,

An almost perfect result until 15:36, then I have no idea what happened.

Hi all,

Although the signal is good the QRM affected the results heavily.
15:00 - 15:14 QRM on screen-shots 1 & 2.
15:29 - 15:57 QRM on screen-shots 3 & 4.
Only the period in between was clear of QRM. In the absence of DRM the QRM can be seen on screen-shot 5. The audio is telephone sounded.

Hi all,

A short log. Deep fading of about 40 dB affected the decoding, curiously no serious QRM!.

Hi all,

Strong signal, deep fading, strong QRM on +5kHz, not a good recipe for decoding DRM.

AM interference from 5 kHz up.
21 kbps and only 5 kHz wide audio do not match.

Propagation problems at end.

Bitrate and audio quality do not match.
Signal sometimes weak in fading and AM 5 kHz up.
