PS: The IF file played OK with both the Gospell and the Avion receivers. 4/64 QAM, but I have no indication of the bitrate. Enclosed is a spectrum of the audio. It seems to stop around 10500 Hz. The music part in the middle of the file was overdriven and sounded poor. Otherwise the audio was very clear.

Terje,

If you have the time, please upload the decoded audio in a good compressed format, e.g. AAC+, so potential buyers can assess xHE-AAC's quality.

On second thought, I don't really have time currently to experiment with my LP DRM transmitter.

I used my LP AM stereo transmitter with the channels swapped.

I never did hear any audio, but it isn't surprising given my GR-216's penchant for needing abnormally higher SNRs for decoding.

Almost same QRM scenario as in my post #218 but worst. ~94% CDA / 32.3 max SNR.

I run this log after the CRI QRM stopped. Then appeared the QRM by VOA weaker than that of CRI, which affected a bit the decoding. 99.9% CDA / 30.5dB max SNR.
