Hi all,
The signal reached up to 42 dBuV and the SNR mostly was > 30 dB, audio was over modulated and clipped. All dropouts caused by deep fading.

Hi all,
Bad results tonight. The results got better after 19:50.

Hi all,
A 175 mins log but good results only between 17:36 - 18:28. The signal reached up to 50 dBuV but suffered by QRM and fading.

Hi all,
Some periods of good and bad results.

Hi all,
Not bad at all for 74 mins, SQ: 99.14% and wavy SNR figure.

Better than Taldom on 9810 kHz at the same time:

Hi all,
Mixed results tonight.
38.6 dB SNR was recorded around 2030, quite a surprise. A mostly unattended log.
Hi all,
Results for today.
Jos.
Hi all,
The results of today compared with the resuults of yesterday.
Jos.
Quite a disappointment this evening (at least compared to this morning)

Hi all,
When the QRM started a big drop in the SNR noticed, then slowly got better.
mitajohn
28-05-2009, 19:18
Hi all,
The signal was very good 40-55 dBuV and sometimes gave SNR over 35 dB. For the BR chosen it sounded very good. Around 17:33 strong co-channel QRM appeared causing decoding problems, which lasted some minutes. At 18:00 strong QRM started and killed DRM, I stopped the log.

30-05-2009, 19:11
Hi all,
Almost the same scenario, as in my previous post, but worse because the DRM signal was not strong this time.

Hi all,
The last 20 mins of the transmission.

Hi all,
A 25 mins log from a clean channel, then QRM started.
mitajohn
11-06-2009, 19:18
Hi all,
The same scenario: Perfect results until 17:59 when QRM started.
mitajohn
17-06-2009, 19:03
Hi all,
The same scenario again.

05-08-2009, 19:19
Hi all,
Perfect results until ~17:58 when QRM started.
Very good reception here tonight.
mitajohn
06-08-2009, 20:09
Hi all,
Strong signal tonight but the decoding affected by the QRM when the signal turned weak due to fading.
mitajohn
13-08-2009, 19:31
Hi all,
Strong signal tonight. Sometimes reached up to 55 dBuV and gave high SNR figures, but the known QRM scenario at 17:35 and 17:59 was followed again, as seen by the rapid drop of the SNR.
mitajohn
14-08-2009, 22:04
Hi all,
A perfect result for 28 mins.

18-08-2009, 19:08
Hi all,
Good results only after 17:36 and up to 17:59.

Hi all,
A 120 mins result with the known QRM problems.

Hi all,
A 200 mins log with mixed results.

This transmission is obviously directed to southern europe, first french, then italian.
Very unsteady reception here in northwestern Germany at the dutch border.
DREAM finally crashed = end of log.

Hi all,
In spite of the permanent QRM at +5 kHz I got the attached results.
mitajohn
09-04-2010, 21:58
Hi all,
Mixed results tonight. The signal varied from 20 to 60 dBuV. Strong QRM on channel as well as splatters from the adjacent channel and the TX on -5kHz, although the SNR sometimes reached 39 dB!. After ~20:28 the signal dropped too much and finally disappeared.

Hi all,
Good results until transmission broke down.

Unexpected few min log.
mitajohn
18-04-2010, 22:11
Hi all,
Mixed results again tonight for 35 mins. The signal varied from 18 to 50 dBuV very fast, causing wide variations to the SNR figure and decoding problems.
Similar results here I think...
Roughly 100% CDA until the end of the transmission. What showed up thereafter I am not sure... :confused: The exiter was still on?
good reception here they even had a little talking about russian tourism in belgium:)

VoR on 31m: Here 9850 kHz is best, then 9750 kHz, and 9880 kHz is worst.

29-09-2010, 07:17
Hi all,
A result for 57 mins. Strong signal and strong QRM on channel as well as splatters from the 9890 kHz AM TX and the TX on -5kHz which mainly affected the SNR and less the decoding.

Hi all,
An unattended log tonight for 4H29.

Hi all,
A perfect result for 104 mins, then the signal got weak and killed by the strong QRM.

Hi all,
A partially unattended log.

Very good, the Perseus will not go much higher in SNR,
but then sudden end of propagation:
Sounded good in French and very good audio in 16/16 configuration, at least in the beginning of the log when I was listening. From around 1730 UTC the log unattended. 291 minutes with 97% decoded audio. I can see a 4 minutes break around 1908, but cannot tell why. :confused:

Hi all,
A result affected by QRM but not too bad.

Hi all,
A 28 mins log. After 20:40 conditions changed and QRM affected the signal.

The audio is not good but one of the best at only 14 kbps:

28-05-2011, 21:13
Best audio ever heard at 14 kbps:
Very good reception except for a weaker period around 1640 UTC.

The signal was getting weak during the last 30 minutes:

24-07-2011, 22:02
Hi all,
Unstable signal and decoding problems due to QRM and finally I stopped of logging. In the first plot I got both services (DRM RUVR 1A & 1B) using two SWs, in the second plot the influence QRM is presented.
I switched over to Santiago around 19 UTC, but at that point the signal from VoR was no good anyway.
Hi All,
Quite good reception during 2 h.with a few drops out.

Hi all,
An almost perfect result until QRM started.

Hi all,
A nearly perfect result. Take a look at the doppler, its almost out of plot limits...

Hi all,
A very good result for about one hour. From 18:07 - 18:15 a break down of audio stream took place.

22-09-2011, 20:06
A result for 50 mins.

A very good result until QRM killed DRM.

An 125mins log. After 21:24 decoding problems started.
