View Full Version : 7275 kHz DW from Woofferton
Hello to all,
New frequency, instead of 7265 kHz. Very strong signal here even with laptop plugged both to phone line and AC power.

Hi,
Yes, DW is now on 7275 kHz, but
The label says English, but it's in German.
The text message reads: Deutsche Welle DRM Sines transmitter
For more information: www.dw-world.de/drm
On this home page you can read:
"Deutsche Welle DRM Frequency Guide (April 2005)"
It's however from April 2006, so it's still too old!
Perfect reception: CDA 99.94%.
Excellent results. Funny mixture of music.
Classic music sounds a bit strange - so you feel that digital transmission has always something to do with data reduction. Effect is less noticeable with jazz and pop music.
Thus restricted sound quality of my active external PC speakers makes no difference between audio feed from DRM or from a portable DAB/FM radio.
Hi all.
Log 129min. and CDA 99%ok . Very strong signal strength.
:)
Hi,
92 % CDA today from DW. Time: 11:11 - 11:56 UTC.

Hi all,
A nearly excellent result althought the signal hardly reached 35 dBuV. After 1130 strong QRM (3 carriers ?!) started and ruined the DRM reception.
Hi all.
Log 140min. and CDA 99%ok . Very strong signal strength. Very good propagation for DRM in this band today.
:)
Hi all.
Log 66 min. and CDA 99ok . Very strong signal strength. Very good propagation for DRM today.
Strong and stable signal, perfect results in the first hour from Woofferton today. Seems only transmissions from Sines are synchronised, as before.
Simone
A very good signal from the new Site Woofferton. Much better than Wertachtal before.
Here is my 4 hours log, a weaker signal in the last hour after the configuration change.
Btw AFS need to be updated.
Simone
Perfect results today, I guess the dips were caused by configuration changes.
Simone
Good results again, lower SNR in the second half.
Simone
Quite good results again today.
Simone
Strong, stable and perfect with a very high SNR. That's how it should be.
Great results here too with a strong and stable signal, the only dropout was the configuration change at 12:00.
Simone
Grest Results once again, the only major dropout within 4 hours being the change of bitrate at noon.
Perfect results once again. It switched off the agc, so the the FST graph does not show anything real.
It is interesting that these Mode changes are not audible with DRWMSWR now. Maybe the configuration change is done now faster than in former times? Normally you have a much deeper dropout in the DRMSWR graph than in Dream.
Excellent results again today.
Simone
Excellent, the only dropout was the configuration change.
Simone
Great results as usual,
Simone
Good conditions again, an additional dip in the graph today besides the usual configuration change.
Simone
Good results as usual.
Simone
Good results apart from what looked like a Tx problem, slightly lower SNR after the braek, low audio bitrate today.
Simone
A weaker signal than usual but quite good results, should still work with the higher bitrate stream, today again 16QAM SDC and MSC, maybe the deep dip was a local problem.

very bad results today, but why ?
to the comparison my result of 07.01.07
Rainer
A somewhat late report spanning 0912 UTC - 1259 UTC from 13th Jan. I was not present, but my log (also) recorded a break in the transmission from about 118 UTC until 1133 UTC.
Pretty good results although signal was not very strong, again only the low bitrate stream :(
Simone
Good results apart from a few minutes around 12:00, back to using the highbitrate stream today.
Simone
Perfect results today.
Simone
Perfect results again today :)
Simone
Excellent results but text messages from DW were not working.
Simone
Pretty good results again today.
Simone
Great results again today.
Simone
Great results again and higher SNR than the past days.
Simone
Excellent results again today.
Simone
Great results again, lower SNR from 10:00- 12:00.
Simone
Perfect reception 160 minutes until sign-off, except for the break at 1200 UTC when I was absent.
Excellent results today, the only dip caused by the configuration change.
Simone
Quite good again today, an additional sync loss at 12:21.

Hi all,
Not bad results but after 1115 turn to really bad ones.
Excellent results in the Swiss Alps last week.
Simone
Perfect results today.
Simone
Great results again today, SNR improved after the dip at 11:00.
Simone
SNR improved again at 11:00, strong and stable signal, no need to use this low bitrate all day!
Simone
Perfect results again today, but still using this low bitrate datastream :( hope this will be changed again.
Simone
SNR improved after the break at 11:00, still wonder about the low bitrate datastream.
Simone
Good results on mobile reception today, still low bitrate.
Simone
Perfect decoding again today, still low bitrate.
There was again a change at 11:00 today, interesting to see changes in SNR and delay.
Simone
Perfect reception with a strong and stable signal.
Strong and stable signal here too, interesting change at 11:00 again today, audio graph not included in the attachment, (actually it is more interesting to watch other parameters than to listen to the bad quality audio ;))
Simone
Almost 2 hours of perfect decoding. I noticed a break at 11 UTC but there was no change in the bitrate. 14.56 kbps before and after 11 UTC. And I could not see any relevant change in the Delay and SNR after the change here at my QTH (see the 30 minute long zoom before and after 11 in the second plot).
A few problems at the beginning, then perfect but lower SNR than most days.
Simone
Bad conditions at the beginning, some problems before 11:00, perfect results and higher SNR in the last two hours.
Simone
Great results on mobile reception, still using the low bitrate stream :(
Simone
One of the most reliable stations, but with poor audio quality, actually not worth listening.

Hi all,
A nearly excellent result although the signal was always below 30 dBuV.
Excellent results again today, still low bitrate.
Simone
Very good here too today.
Great results as usual, somewhat lower SNR from 1000- 1200.
Simone
Perfect results today.
Simone
Great results again but still using the low bitrate.

Hi all,
A weak signal until it almost disappeared gave the attached results.
Pretty good results on mobile reception again today, low bitrate :(

Hi all,
Bad results today.
Perfect results again, low bitrate :(
Simone
Good results again, still low bitrate :(
Simone
Looks like there were some configuration changes today probably causing the dips, lower SNR after 12:00, donīt expect problems due to mode A.

Hi all,
Here is an unattended log. Periods of very good and very bad results.
Good results, no problems due to mode A.
Simone
Perfect results on mobile reception today.
Simone
Pretty good results in mode A, IR looking good, why not use the same datastream as from Sines (15725 kHz also using mode A) it should also work, and sounds even better.
Once again great results on mobile reception.
Simone
The biggest challenge of DRM will be indoor reception. As you can see in the graph, I got 20 dB attenuation indoors.
Good results as usual.
Simone
Donīt know what caused the two dips, otherwise pretty good results.
Simone
Two dips again today, lower SNR than usual, apart from that pretty good results.
Simone
Great results although SNR was lower in the last hour with a longer IR and a strong second path.
Simone
Lower SNR than on other days, but perfect results anyway.
Simone
Perfect decoding again today.
Simone
Good results, dropouts due to bitrate and mode changes.
Simone
Pretty good results today.
Simone
.. and again today, higher bitrate would be no problem.
Simone
Excellent results, bad audio quality.
Simone
A few dropouts despite the high SNR.
Simone
A late start logging, but a good result (except for the poor audio). The SNR was highest in the beginning, dropping slowly.
Strong signal, a few short dropouts despite the high SNR.
Simone
Pretty good results today.
Simone
Hi,
Very good reception today of 'Deutsche Welle DRM transmission'.
Time: 08:17 until closedown at 10:00 UTC (101 minutes).
Result: 99.8 % CDA.
Pretty good results as usual.
Simone
Perfect apart from the dropout at 0935.
Simone
Lower SNR and signal strength from 0830- 0900, but good results.

Also lower SNR between 08:30 and 09:00 with more dramatic results in crowded Essen:
Some problems in the first minutes, a slightly weaker signal with better SNR in the second hour.
Simone
Good results, higher SNR again in the second hour.
Simone
Similar results again today.
Simone
No problems with mode A at the beginning, good results also in the last hour.
Simone
Good results in both modes, not sure about the SFN.
Simone
Good results again today.
Simone
Good results again today, in the second hour good signal from the UK, not much from Moosbrunn I guess.
Simone
Perfect results again today.
Simone
Good results again today.
Simone
Only an unattended log, seems there was a problem at the start.
Simone
Good results again today in both hours.
Simone
Interestingly SNR increased in the second hour today.
Simone
Good results, SNR increased in the second half.
Simone
Perfect in both hours.
Simone
No chance for good audio when SFN with Austrian Transmitter Moosbrunn started. Seems I'm too close to Vienna or the beam is not covering me.
But the first 1/2 hour nearly perfect.
Strange log compared to yesterday.

Great results in both hours,SNR increased in the second hour.
Simone
Good results again today in both hours.
Simone
The 2nd big hole was my fault, I guess.
Great results for both hours.

Good results but transmission stopped some minutes too early.
Simone
Good results again today.
Simone
Hi,
Also on this date, sep 22, perfect reception.
Time: 08:05 until close down at 09:00 UTC.
Result: 99.84 % CDA.
Great results again.
Simone
Perfect results today.
Simone
Perfect propagation on 7Mhz today, firts test of my portable reciver and 1m telescopic antenna on this band. Only small local qrm so CDA 99.86% ok !!!.
:) :)
Seems there were some problems in the second half yesterday (same on 6130 kHz in the evening), no problems today, but lower SNR than usual.
