RRI @ 9760 kHz

The signal was there, but the SNR was only about 1 dB throughout the broadcast. I thank RRI for the good choice of frequency, but their digital configuration needs to switch to 16 QAM modulation so a listener on the East Coast of NA can decode it. Philip might stand a chance.

1700 to 1800Z

RRI 9760 kHz Tiganasti reception near Atlanta, Georgia, USA

Not much point in logging this particular transmission as it is too early for good propagation to this "neck of the woods". That being said, this afternoon's reception - no audio decoded, 12.14 dB max SNR.

Thumbs up RRI 9760 kHz Tiganasti reception near Atlanta, Georgia, USA

I happened to look at this frequency this afternoon, about half way through the broadcast, and noticed that the transmission was coming through really well, using a new configuration of 11.64kbps and running 16QAM.

The reception, for this time of the day, was an excellent 80.84% audio decoded and 20.71 dB max SNR!

The audio bandwidth showed as only 3.5 kHz, but the quality was pretty good (attachment 2).

This afternoon's reception - no audio decoded, 7.75 dB max SNR.

As mentioned before, this broadcast is too early for normal propagation to the SE USA. The north-east corner of North America should have a good chance of decoding audio.
