Ambient Conditions: Unknown as I wasn't planning on posting this log. PC off ( 0 dB loss)

I suspect the received signal is from the rear lobe of the transmitter over the northern pole.

Today we heard Vividh Bharti in 14.56 kbps and the result was 99.84% decoded audio. Hands off the bitrate-switch!!! This is what we want in order to get uninterrupted reception.

14 kbps plus 16 QAM on MSC should be adopted by 75 % of the international broadcasters if they don't want to change configurations seasonally. I received a peak SNR of just 3 dB this morning on the Sinhala service. Hopefully, AIR will KEEP this current configuration and extend it to most of their other international broadcasts as well.

Today it is strong, 30 snr, signal but, no/low audio perhaps due to broken audio patch cable, thus making the program, a farce.

15050 kHz HPT AIR Khampur, India, reception near Atlanta, Georgia, USA

Thanks to mitajohn for his report which alerted me to this 1300 UTC AIR Khampur transmission which contrary to an earlier posting (and schedule) is still there.

This morning's long path reception report - no audio decoded, 6.26 dB max SNR.

The screen ID still showed up at a low SNR of 2.5dB! (Attachment 2).
