Voice of Russia from Kaliningrad on 6105 and 7325

Hi,

the Voice of Russia is on air now on this new frequency in German.

Strange label but strong signal.

Edit: Just added the log. A strong AM station began broadcasting at 1300 UTC on the same frequency and killed the DRM signal.

Looks like it was a transmission from Kaliningrad: http://kaliningrad.rtrn.ru/news.asp?view=10450

Kai Ludwig reports in A-DX that there might be a transmission at 2000 and 2300 UTC on 6105.

Indeed, on the air now on 6105. Here's the log. Strong QRM and fading, so 8,45 % CDA only.

7325 kHz VOR

Hallo,

hervorragendes Signal mit groer Konstanz.

Die TX-Parameter in DRMCalc scheinen nicht zu stimmen.

Thanks for adding this transmission to the official DRM schedule.

PERFECT reception right now, 28 dB SNR. Bitrate could increased a bit, 14 kbps sounds quite "special"... audio level is a bit high.

Just heard this new frequency in the program -> offical?!

Good results again but bad audio-quality as usual. But anyway, it was worth listening to! Voice of Russia had a small joke-session today... haha.

Thumbs down DRM car radio

Gescher-B525-A43-A1-B58-A2-A33-Paderborn
Reception quite good in the car, but the audio quality is very poor!
The sound is compressed, clipped, distorted, simply not suitable for DRM.
And even more this constant terrible background noise in the story about Novgorod (they think it is music) was a real torture.

Good rf signal, SNR Maximum [dB]: 40.7
Still regular resyncs on my side using VAC.
Audio level still much too high, sound is compressed and clipped!

DRM car radio

Nottuln-B525-Gescher
Bad audio quality also out of the car hifi speakers, bitrate too low.
Strong mumbling noise behind voices and music sounds very distorted.

First log on the Russian broadcast: Quite good - Nice to see them in the air on this frequency, one of the good ones here. Audio quality is not perfect at 14.06 kbps, but I think it's okay.

Later I tuned to KBS so the second part of the log will be added later. Unfortunatly, this log will start with CPU overload and a nice drop-out while uploading the first log right now.

Edit: Just added the second part - perfect!

Strange result:
SNR was changing between exceptionally high and low. During the low periods the snr spectrum behaved like in a thunderstorm, but I could see nothing like that in the panadapter.
SNR Maximum [dB]: 42.5
If the result is right that was a new record for my Flex-5000A.
I'll check tomorrow if I can repeat that.
The audio was in low quality at very high level.
