17715 kHz AIR India to E Africa

I've been seeing this one on a regular basis here in NZ, but never good enough for any decoding.

I see the online DRM schedule seems to have all the AIR broadcasts entered in IST instead of UTC? It shows this transmission at 1000 UTC, but other sources on the net (eg short-wave.info) show this broadcast correctly.

Cheers, Chris

A little bit of signal here on 17715 kHz today - enough to get the id but that's all.

Cheers, Chris

I saw this one by "mistake" early this morning while looking for something else. Only two minutes in the log.

Logged a few minutes of this AIR transmission today in NZ, between checking on RRI transmissions. No decoding possible though.

I tried to log 17715 kHz this morning and set the DRM-Plotter to 0315-0530 according to AIR's schedule on their web page. No traces in the log before 05 UTC but after that the signal improved and I got 0.04% decoded audio. Now I wonder, did the transmission really stop at 0530 UTC?
