88.15% decoded audio during this 119 minutes long log. The SNR was much lower tonight. :confused:

High SNR and lots of (possible) audio, but someone had forgotten to plug the audio in. The result was 150 minutes of pure silence (not even hum...).

95% CDA until 2030, then conditions deteriorated. Only 67.5% CDA for the whole log.

It seems like th OTH (over the horizon) radar was operating about 15 kHz up from AIR all the time during this log. Anyway, the OTH ruined everything completely.

One TX failure around 1852 UTC and then around 2045 the signal got very weak, so I stopped the log after a while. Max. SNR was 28.7 dB.

I was unlucky for a good reception of RRI so I tuned to 9950 kHz and I noticed a lower BR and new label. I got a good result for ~45 mins then it turned bad.

Thanks John, I wasn't listening until I saw your notice about the new label F M GOLD, so I tuned in for a while. Almost 98% decoded audio. 14 kbps is enough for the kind of audio they transmit. :rolleyes:
