I noticed that the upper side of the DRM waveform looked very distorted throughout the broadcast, and when they went off air at 2229 UTC, it was very noticeable that there was some sort of digital 'multiplexer' signal (probably military) covering from about 7552 to 7559 kHz, and I'm wondering if this was having a negative effect on the signal? It wasn't noticeable under the DRM noise whilst the station was on air, and I wouldn't even have guessed that it was there during the broadcast. It would be good if they could move down to 7540 kHz to avoid it and see if that made any difference to the quality of the decodes.
