It started with one minute with audio and Protection 0/0 and high SNR . Then there was a TX break for about 12 minutes and the transmission came back on the air with Protection Rate 1/0 instead. From 17:41 until the end the decoded audio was 99.9% and the SNR was back to normal after the last few days with no decoded audio. The problem, whatever it may have been, has been resolved.
