The transmission was on air from 18:00-19:30 UTC. There were no obvious breaks in transmission and the SNR was very constant. There was 100% decoded audio.

18:00-21:00 UTC Planetary K-index 2-. Local K-index 2.

Planetary A-index: 6. Solar flux: 99. SWPC Sunspot number: 36.
Sunset 20:24 UTC.

N.B. The time on the plot is wrong by +1 hour.

Actually there were about 2 or 3. However unlike previous occasions this was only for a few seconds at a time rather than minutes. Was also checking the spectrum on sdr# so saw the carrier disappear.

Hi Mike, thanks for the correction, you have an advantage over me in that I can't see the spectrum of the signal.

No signal was received tonight, so I assume it was off the air.

Hi Neil,

Our logs look much the same with the breaks and flaws around the same time.

Hi Terje, good to see your log, there seemed to be a change to the programmes on the 10 Jul 2015, as instead of a programme called '60 Minutes' there was an hour of local pop music.
