instead of a log a short audio recording from today.....
Even if this is a test transmission - is this a promotion for DRM ????

Hi all,

....And when QRM almost cleared channel the signal was very weak.

Strong and weak periods today. But quite good results today. Sound was OK, but surely could be better.

A very weak period from 2140- 2200, otherwise not bad, MOT still not working.

AIR Khampur to Europe on 9950 kHz
Hi all,

All India Radio (AIR) will start some DRM broadcasts beamed to Europe from Delhi Khampur tomorrow, October 2nd.
The QRG is 9950 kHz, 1745-2230 UTC.
There's a strong AM carrier on the frequency right now, AIR testing I guess.
Please note that there is also a DRM transmission for India on 6100 kHz at 0430-1130 UTC but I think we should open another thread for this broadcast?

Hope to hear and see some DRM from India again tomorrow! :)

Threads merged.
Please post results on the new tests from AIR on 9950 kHz in this existing thread.

Hi All

9950 kHz peaked up enough to be decodable for a few minutes this morning here in Wellington, New Zealand. Seems to have faded back down into the static now though.

Cheers, Chris

Hi all,

At last some variation in the DRM output... AIR started with a test tone a bit before the scheduled start, but soon music flowed through the speakers in full Mono. There were no text messages until I switched off at 21 UTC.

Most of the time the signal was around 27-35 dBµV and the decoded audio was >99.5% throughout the log. There were some audio problems at times. The French programme was studded with blups around 2020 UTC. Around 2040 UTC there was no or very weak audio, and at times there was only hum. Anyway, it is a test transmission! (?).

On the whole, the low bitrate produced a very stable reception.

Hi all,

SQ = 99.8% for about 4 hours. The signal was rather stable and reached up to 55 dBuV with limited SNR. Audio: Low-Fi.

All times are GMT. The time now is 20:50.
