rather good after 09:56 UTC. Still problem of interferences. There is also NRZI AM transmission at 9765 kHz. It is interesting to listen both transmission at the same time.

ok. I'll include also the spectrum of 9870 DRM + 9765 AM at the same moment. The zip file is 5 seconds audio of DRM and AM again at the same time.

Hello all,

good today in South East Germany. At 10:57 according to their schedule the TX-antenna direction was changed from 0 degree (1st log) to 325 degrees (2nd log). 320 degrees would be best for my location. The log shows no changes in SNR between 10:57 and 11:00.

No RTTY-QRM here, around 11:30 two AM-stations (5 kHz down and in the center) became stronger.

The rubbish on 9873 was clearly seen here too. Around 10:40 it had disappeared, and only a carrier on the RNZI frequency continued. The best reception here is between 12:00 and 12:40 UTC.

The usual 40 minutes slot became a bit shorter today due to a very strong AM station 5 kHz down.

The reception was pretty good today until the co-channel AM popped up as usual at 12:38 UTC :mad:

More or less the same as yesterday. The signal was quite strong in the beginning, but there was heavy Fading. Towards the end of the log the signal gradually got weaker. Then the AM blocker popped up - as usual.

Rather good signal. AM station 9870kHz interference was rather low (only 10 dB over DRM) and 9873 kHz RTTY was off.

Forgot all about 9870 today and only caught the very last bit. The QRM usually starting at 12:38 UTC into the hour did not start until 12:45 today. Only a mini-mini-log today.
