Hi all,
A rather good result. Many TX problems after 1750 and I stopped the log.
John.
Tx problems around 1710 and in the last 10min like on 9470 kHz earlier today, also a period with a weaker signal from 1545- 1615.

Hi all,
Not so good.
John.
A weaker and instable signal towards the end.
Simone
Some problems and not using the regular datastream today.
Simone
Hi,
A 45 minutes report, which can only be labeled as "very good".
Terje
An almost four hour log with a very good result.
Roland
Much better than 7320 kHz at the same time with all its interference.
Roland
They seem to have big problems today in Norway. Some minutes of silence and then the transmission ended...
A few dropouts (using DRMSWR), not too bad.
Simone
A lot worse today, especially in the last hour.
Simone
And even worse today :(
Simone
Rather bad after 1700 UTC because of heavy interference.

Good signal in the afternoon, but sometimes strange audio crackling.
Attached is a short mp3.zip with the distortion.
At around 16:30 UTC signal became unreadable due to bad impulse response,
you can see the backscatter.
Hi all.
Her is small test log from this freq. DRM spectrum is total brake down all time her in my QTH. It is only for info to James on BBC. I can never listen to this transmission. This problem most come from bad propagation .
See my picture over Cannel Transfer Function.

Hi all,
This is the reception here with a strong QRM on 7460 kHz.
No transmission on this frequency today?
Simone
Much better than on 9470 kHz before.

87% audio though signal at 21 +- 2 dB.
Paulo
Two hours from 17-19 UTC with mixed feelings. Quite a lot of drop-outs, which made listening a bit tiring.
Some dropouts in the last hour.
Simone
Good results apart from two dropouts when using the backup feed.
Simone
A weaker signal from 1700- 1800, good results for the rest of the log.
Simone
Better than yesterday.

Some problems at 1700- 1800, also an "audio only" transmission today, no data services, textmessages etc. :(
Simone
Started great, but from 1700 only a weak signal, again an "audio only" transmission all day.
Simone
Bad reception and volume always to the max.
Perfect results and using the regular datastream again, but transmission started an hour later and stopped an hour earlier than scheduled.:confused:

About 90% audio decoded in Rome using a Sangean ATS 909 modified for DRM.The antenna is the receiver's one (1.20 m)
Pretty good results again today.
Simone
Good results as the past days.
Simone
Some dropouts in the last hour.
Simone
Perfect first hour, then some interference started at 1700.
Simone
Pretty good results today.
Simone
An unattended log. Between 1700 and 1730 there were some problems. Problems again towards the end of the log.
Great results with the DWT, antenna inside hotel room.
Simone
Apart from some interference at 1700- 1720 quite good results.
Simone
Some dropouts from 1700- 1730, otherwise good results on mobile reception today.

Hi all,
Very good results except of the interference period.
Quite good results, only a few minor dropouts in the last hour.
Simone
I wasn't there during the worst part, but it must have been AM or something on the channel or nearby. You can see traces of it in Simone's 2nd log. Much worse here. (And I am not so far from Geneva) :rolleyes:
Very strong signal from Kvitsoy, but Delay over 10ms after TX stop 1503UTc .
Delay over 10.56ms give drop outs and signal stringth from S9+30db to S9 .
Log is 68min.
Here is the same segment logged in Switzerland. The first TX break was DRM stream related, the second I'm not sure what it was.
And the whole log: From 1700 - 1730 there is something causing trouble.
More or less the same today. The later part of the log was unattended. 1710 - 1730 is still problematic.
There is definitely co-channel QRM from 1700 - 1725. Looking at the SNR Spectrum in Dream reveals a deep dip in the centre of the channel. Up until 1700 the CDA is virtually 100% and from 1726 until the end it is 100%. Between 1700 and 1727 the CDA is only about 35% here.
Interference was not so bad here today (although I remember it from transmissions back in April), more problems in the last half hour here.

Hi all,
Reletively strong signal but with severe problems due to interference. The rest result is about 99% SQ.
The same AM-QRM here and I think it was even more aggressive today. My log is about 3 1/2 hours long.
