AIR on 15410 kHz for Australia/New Zealand

AIR continue to pick useless frequencies for their evening transmission, claimed to be for Australia & New Zealand. Absolutely no trace of the signal on 15410 kHz at "home base" at Marahau, and only 3-4 dB on the NZRDXL Northland SDRs. They really should drop the "& New Zealand" from the listing on their schedule. No-one in NZ is going to be able to receive anything.

Cheers, Chris

I actually pick up this transmission in Sweden! But SNR only around 10 dB, hence no decoded audio. On the other hand several transmissions from RRI and WINB aimed at Western Europe does not show a trace of signal at my QTH.

All India Radio GOS1 logged for 49 minutes from 1010-1059 UTC. Propagation was back, or there was no transmission last night (?). Much more (poor quality) audio this evening. First half hour with perfect decoding. The signal suddenly got much weaker around 1040 UTC. Max. 21,65 dB SNR and 71,01% decoded audio. Music in both channels around 1020 UTC. The audio in ch. 2 was distorted.

This transmission continues to avoid New Zealand. So weak Dream can't even sync.

Cheers, Chris

AIR with two services, neither of them with any sound at my location.
Otherwise #2, RAGAM with the label Country music could have been interesting.
Time: 10:31 until cd @ 11:00 UTC.

According to Chris excellent schedule the transmission should be 10-11.
But I started "listening" at 09:50 and AIR was on the air.
No audio, but I'm not in Australia...
I doubt that the Tx is in Nauen, which Terje's logplot shows.

The transmission starts at 0945 UTC. Regarding "Nauen", I suggest an update of the drmtransmittersites.txt would be helpful. The first line in the file is the date of the file. A click on "TX Sites" shows the date of the current sites list.

PS: Nauen used 15410 kHz for DRM transmissions to the German ship Andernach back in 2013.
