Hi all,
strong signal today at 14:45 UTC.
Unfortunately very bad audio quality, only 8.0 kbps.
73, Klaus
Hi all,
here is my half hour log, no label but the text messages and the test CD they were playing mentioned it was a test from Kvitsoy/ Norway.
73, Simone
Very strong and stable signal.

Hi all,
Relatively strong signal, good results for 45 mins, see attachment.
John
Hi all,
strong signal, no interferencs this morning, short IR, good results, a Tx problem at 1152?
73, Simone
... and perfect reception also towards the end of the transmission, seems to be the best frequency from Norway for me.
Simone
Hi,
a very strong signal at the beginning. Around noon local time (1000 UTC), signal became weaker.
The large dropout was caused by local pulse noise, presumably from construction work around the house.

Norway/UK: Telenor/BBC World Service enter digital broadcasting agreement
Text of press release by Oslo-based Telenor on 31 August; subheading as published
Telenor-owned Norkring has entered into an agreement with the BBC World Service for digital broadcasting over shortwave, DRM [Digital Radio Mondial]. As part of the agreement, the BBC will be among the first in the world to broadcast over DRM.
From Norkring's transmitting station at Kvitsoy, signals will be broadcast to Central Europe. This new agreement with the BBC is an important step in the digitalisation of shortwave, which actually has the capacity to achieve global reach. The agreement involves broadcast of the radio channel BBC World Service "English for Europe" for an initial period of 18 months. The BBC is also using UK-based transmitters owned and operated by VT Communications (VTC) to provide a multi-frequency network aimed at Benelux and neighbouring countries.
"For us this as an exciting partnership with one of the world's leading broadcasters. The BBC is a driving force within DRM, and contributes to set the standard for the future role of shortwave," said sales and marketing director at Norkring, Per Maltun.
The first major test will be the launch of receivers for DRM at the world's largest exhibition for consumer electronics, the IFA in Berlin 2-7 September 2005. [Passage omitted]
About Norkring
Norkring is Norway's largest distributor of broadcast programmes. The company owns and operates most large transmitter stations for terrestrial broadcasting in Norway. Norkring has a nationwide infrastructure that consists of 6,500 transmitting units, installed at 47 main stations and 2,700 smaller stations. Norkring is wholly owned by Telenor, and is part of the Business Segment Telenor Broadcast.

Hi all,
many dropouts today, even at the lower bitrate and using EEP, signal was weaker and problems caused by a co- channel interferer, see attachment

Hi all,
It started with a weak signal but enough for good result. Then gradually got strongerand stronger when finally I changed the sensitivity of the receiver to avoid intermodulation products. This is an almost 5 hour log, quite good. The sound was good which breaks only at big dips. Overall impression was very good. See attachment.
John
Hi all,
strong signal again today, not sure what caused the dropouts (might be an USB problem), see attachment

Hi all,
pretty good again today, see attachment
73, Simone
Rather good today.
Roland
Hi all,
My first impression of this frequency is very good. Stable conditions, good overall. The report is enclosed.
Terje
Hi all,
quite good again, no datastream problems, see attachment
73, Simone
Very good reception. Looks as if this will become my favourite frequency.
Roland
Hi all, hi Beeb,
9 MHz was considerably better than 7 MHz, a greater distance to the TX, and a stable SNR. Only the programming could be better according to my opinion...
73s
Terje
Hi,
here is report no. 1, I had to interrupt in order to test something...
Edit: I have replaced the wrong file
Roland
...and here is report no. 2.
Roland
Hi all,
strong signal this morning, still datastreamproblems from the BBC but audio on this frequency was always OK, but not 7320 kHz
73, Simone
Hi all,
Today there was something very wrong with the transmission... Whoops! just at the time of writing some sound appeared at 1017 UTC.
73
Terje
Hi,
there are still interruptions, moments with carrier, streaming or sync problems and what looked like a switch-over from MDI to analogue audio at the encoder. During the latter, there was a large difference in audio levels.
Roland
Later, there were fewer problems.
Roland
Hi all,
strong signal near Groningen/ NL, 7320 kHz is a lot weaker but also good decoding, higher bitrate again, no MM service today.
73, Simone
Excellent Music review programme. Signal on 9480 much lower.
Hi,
here is my report covering the period during which the ionospheric disturbance occured. It started at 09:49 UTC and after a while, signal slowly came back. The dropouts in the left and right part of the report were transmission related, signal was missing completely then.
Roland
Hi
Some very faint signs of 9470 here in Wellington today.
First time I've seen any DRM signal from Norway here.
Cheers, Chris
Hi all,
Quite good reception today despite talk about propagation problems.
73s
Terje
Hi all,
very strong signal on this frequency. Perfect decoding the time i monitored.
73, Daniel
Very weak signal most of the time.
Around noon, signal was weaker than usual, perhaps this was caused by remnants of yesterday's ionospheric disturbance.
Roland
...and for me reception was like this....
Hi,
here is my report including today's sudden ionospheric disturbance (SID). Signal recovered very slowly and did not reach its prior level again. There was also on-channel and off-channel interference from the East and even from as far as Australia (broadcasting to Asia on 9475 kHz).
Roland
Hi all,
find attached the result from 7h30 to 15h00. The SID can also be seen clearly starting 12h50. Signal only recovered slowly as already mentioned by Roland.
73, Daniel
Hi,
signal went up and down by more than 40 dB today.
Don't know what caused the dropout as I was out of the room then.
Roland
Hi all,
Forgot to load up this yesterday. My log overlaps much of Roland's as a comparison. The propagation yesterday was a bit "bumpy".
73
Terje
Hi all,
Today's report was quite OK.
Enclosed is a log for about one hour up till 1000 UT.
73
Terje
If my receiver wouldn't be limited in its AGC capabilities as it is, reception would have been perfect and the dropout wouldn't have occured. Signal was rather strong at the beginning of my logging period but suddenly dropped by a large amount and did not regain its previous strength again. I had to turn gain up quite a bit then and even had to increase it further over the course of my logging period. It looks as if the ionospheric layer that initially gave me the strong signal did not support this path any longer when the signal strength dropped and another ionospheric layer took over delivering much less signal.
Roland
Hi all,
Good reception up till 1120 UTC, when the signal became very weak. During my lunch hour there was a break in the log, for which I have no explanation.
73
Terje
A good signal at the beginning which later suffered from ionospheric disturbances during which both 9 MHz and 7 MHz were almost completely dead here. In fact, the signal from Kvitsoy was one of the very few that were still detectable.
Roland
Hi all,
More than one hour blackout. Signal disappeared at 0835 UTC and was gone for about one hour. The Sun is up to something...
Terje
PS: An M8 flare at 0840 UT was the problem...

49479 Ibbenbueren - A30 - A31 - 48712 Gescher
Good reception in the car later this day.
A few dropouts were cause by high voltage power lines crossing or close to the autobahn.
Hi,
again, signal was rather weak today with the ionosphere still being a bit in disarray.
Roland
Hi,
again, signal was weak and even decreased further during the course of my logging period until I changed over to 7320 kHz where conditions were not much better either.
Roland
After experiencing bad conditions on 7320 kHz, I retuned to 9470 kHz where conditions had stabilized. So here is the second part of my report.
Roland
Hi all,
a weak and unstable signal today, see attachment
73, Simone
As to be seen on BBC's map I am rather in the target area of Rampisham than of Kvitsoy. Nonetheless 9470 was quite good at the beginning, but became worse and worse during logging. So from 10:50 I switched to 7320 where SNR still was somewhat lower, but fewer 'errors' occured. When I stopped the log Kvitsoy reached 12-14 dB SNR only.
Btw. with my equipment real reception of 1296 kHz is impracticable before sunset.
73 to all of you, Andreas
Hi all,
quite strong signal here. Reception almost perfect between 11h00 and 14h00. Dropouts seem to be TX related.
73, Daniel
Quite good reception, but a lot of TX problems, that caused most of the dropouts. Tthe DRM broadcasters should really fix this before x-mas. A normal listener will not accept this. SW reception is not always easy, so every TX related dropout must be avoided!
Until 11 UTC signal was weak around S7-S9, but good decoding. After 11 UTC it got stronger up to S9+10dB.
Quite a weak signal at times, also some interference. Later, signal strength recovered. I also noticed a few TX interruptions.
Roland
Hi all,
some dropouts due to a weak signal, others were Tx related, interestingly the dropouts that occured around 1145 were exactly the same on 7320 kHz from Rampisham.
73, Simone
Hi all,
signal was weaker than from Rampisham, the datastream problems occured on both transmissions, during the two 20min breaks (at 0930 and 1130) Kvitsoy continued with lower bitrate, dropouts during switching, things improved from 1152 after the configuration had been changed (the EPG and textmessages had been removed, audio bitrate 20.96 kbps)
73, Simone
No text messages and several TX interruptions, good reception otherwise, see report with waterfall plots.
Roland
Hi all,
only an unattended log, so no idea what caused the dropouts, maybe again some datastream problems at the beginning?
73, Simone
Hi,
My log was also unattended - very good SNR and decoding except for a 15 minute dropout at approx 18:10 UTC - cause unknown.
regards
Bob
Hi Bob,
could it be that you mixed up the frequencies? 9470 kHz is only scheduled until 1500 UTC, I guess you have been listening on 7465 kHz from Kvitsoy ;)
73, Simone
Hi,
the dropout at about 9:05 was caused by local noise pulses of unknown origin that were so strong that I even heard them on a local FM signal.
Roland

58791 Werdohl - A45 - A02 - A31 - 48712 Gescher
To the end 9480kHz was much stronger and a carrier on 9475kHz both giving problems.
Hi all,
a few dropouts in the first 45min, perfect results later, see attachment
73, Simone
Hi,
a much better signal than during the past few days but still also a somewhat weaker interval.
Roland
Hi All
Faint signs of Kvitsoy again here today, but far too poor for any decoding.
Cheers, Chris
Hi all,
And this is my report from a slightly closer location to the transmitter ;)
Terje
Hi,
Great reception from 10:30 - 11:30, good before then. Audio quality of speech sometimes has a rather 'rough' edge to it.
regards
Bob
ps Simone - I just noticed your post - you are right - I entered the wrong frequency in Dream on 19.9.05. I must have been in a Dream myself but I think I have got it right today !
Hi,
I first thought that I had witnessed a sync problem during my logging period but when I compare my result with the post above, I can't see any correlation, so I must have been mislead by interference.
Roland
Hi all,
perfect results today for 5.5 hours, audio quality decreased with the lower audio bitrate today after the changes last night .
73, Simone
Currently (0837 UTC), there is no DRM signal but only a carrier with a little hum from Kvitsoy for quite some time now.
Roland
Hi,
Still no DRM signal at 09:28.
regards
Bob
Hi all,
Hm, but *whose* carrier? Something was logged and the Carrier Impulse Response was sighted also.
However, I gave up around 0940 UTC for this session.
73
Terje
Hi all,
perfect results after a delayed start :)
Btw no DRM signal right now on 7465 kHz from Norway.
73, Simone
Hi,
I retuned at 14:30 and got a good DRM signal, so I don't know when the transmission problem was fixed.
regards
Bob
Hi all,
RF Carrier from 0700 UT, interruption at 0713 UT, then the carrier came back but still no DRM.... The signal is nice and strong, but that's little comfort... :confused:
Terje
Hi,
9470 back today ! Very good results this morning.

Bob
Hi all,
This is the result from today. The radio was unattended, and the dropout around 11 UTC I cannot explain.
Terje
Hi all,
perfect results from 0915, see attachment
73, Simone
Hi,
a few dropouts due to fading or local noise pulses.
Roland
Hi,
Overall very good today 13:30 - 15:00.
regards
Bob
Hi all,
Unfortunately, the signal strength was rather weak this morning and at times I lost the signal almost completely. During the weakest moments, the Channel Impulse Response looked more like a heap of rubbish, which accounts for the dropouts in the log.
Terje
Hi,
Perfect 100% decoding for 4 hours this morning : 08:00 - 12:00, high SNR also.

Hi all,
Although the signal was stronger today between 09 and 10 UTC, the Channel Impulse Response was more like a heap of rubbish. The result, however, was still rather good, as can be seen from the enclosed log.

Not bad. On this frequency, I always notice a period with a weaker signal around noon.
Roland

Roland
Hi all,
I agree with Roland; at noon CET the signal drops to almost S0 which causes the dropouts. According to Juliusruh's Ionogram, the MUF for 1000 km shows 10 MHz, but the signal was much stronger in the morning.
Terje
Hi,
not as bad as in Switzerland but also a weaker signal around noon local time.
Roland
Hi all,
pretty strong and stable signal all the time, see attachment
73, Simone
Hi all,
An log from a couple of hours from 0720 - 1145 UTC this morning. Quite stable conditions and SNR 20 - 24 dB. I looked at the S-meter from time to time. S7 in the beginning, peaked around 0830 with S9 to decrease to S4-5 an hour later. The S-meter showed S4 - 6 during the last hour and a half.
Terje
Not bad with a weaker period. The dropout occured when the signal became weaker and when I tried to compensate this decrease in signal strength by more RF gain. Perhaps it's a pure coincidence but it may well be that the larger gain resulted in some intermodulation products which led to a decrease in SNR.
Roland
Hi
Not so good as usual today...
Terje
Only a short period with weak signal.
Roland
Hi all,
a weak start this morning for the first half hour, see attachment
73, Simone
Hi,
there was a break in transmission at 10:48 UTC.

This seemed to be a datastream problem, as it also occured on 7320 kHz from Rampisham, will post results later
Simone
Hi all,
a weak signal until 0725, then good results, see attachment
73, Simone
Quite good despite a strong on-channel carrier during the last 15 minutes.
Roland
Hi,
same interference problem as yesterday during the last few minutes.
The first dropout was caused by intermodulation after I had increased RF gain. Although the spectrum plot looked unchanged, there must have been intermodulation products that were causing a low SNR because the condition could be reversed by turning back RF gain.
Roland
Hi all,
it seems reception on this frequency starts later each day, today no decoding for the first 40 min, which is not really a problem concerning BBC WS as Orfordness and Rampisham can be received at this time.
Simone
... and no problems later today, see attachment

Simone
Signal noted in Wellington today, but too poor for any audio.
Cheers, Chris
There were some interruptions in the transmitted stream today. These probably originated at the BBC because the audio level was also low at times. However, I also watched an interruption followed by - what seemed to be - transmitter tuning.
See screenshot of the waterfall plot for a sample of the interruptions.
Roland
Hi all,
quite good besides some Tx related problems, see attachemnt
Simone
Very good except from TX interruptions, also see my previous post on this.
Roland
Hi all,
yesterdays interruptions were for a variety of reasons.
The long interruptions early in the day were due to some IT related maintenance on the DRM Modulator (think scandisk!)
The short interruptions with low audio were experiments with a back-up MDI over the internet. As experiments they were a complete success but as a service we still have some work to do.
The interruption with retuning was an taking the data stream off the signal to provide more audio bandwidth.
We have also "tuned" the audio processing before the input to the AAC encoder for both HF & MF transmissions - please let us know if you think it sounds better or worse.
Julian

Yesterday on the MW transmission from Orfordness, I once thought that it sounded better but then I discarded this thought since I saw no reason for it. I then thought it might as well have been my ears that had fooled me. ;)
But today on 9470 kHz, it sounds a bit dull, audio bandwidth seems to extend only up to 7 kHz, at least on this world music programme that is currently running.
Roland
Here is the audio spectrum plot, taken at 08:51 UTC on 9470 kHz.
Roland
Hi Julian,
any news from attempts to suppress the clicks during the Greenwich time signal? They are still there today, albeit very much subdued as a result of the low audio bandwidth.
Today, voices on 9470 kHz sound a bit as if they are coming out of a radio tuned to a local AM station due to the low audio bandwidth.
But you should well be able to listen yourself to Kvitsoy transmissions in London, so there is no need for me to record it and send the recording by mail.
Roland
Hi,
7.320 MHz sounds the same, 7 kHz Audio at the most.
Enclosed is a log from this morning from 0836 - 1108 UTC.

There was no interfering signal, the spectrum looked perfect, the impulse response also looked normal but nevertheless, audio dropped out and SNR was momentarily low. Perhaps this was somehow TX-related.
Roland
Hello to all,
Not as good as usual here. Many short dropouts, due to more fading, but the whole programme could be understood. Attached report shows comparison with a reception on 5th nov.

Hi,
there was some fading on the signal today and I had not adjusted the gain properly to take care of that. A perfect result after I had adjusted gain properly.
Roland
Hi,
Perfect results 11:15 - 13:30.
regards
Bob
A perfect result in Munich.
Roland
Some interference from carriers +/- 5 kHz off centre today.
Roland
Hi,
Perfect again today 11:30 - 12:40.

Bob
Hi,
I have just heard a word repetition on 9470 kHz and I already had the feeling that there was one on another day last weak but then I was not 100% sure about it, so I didn't post it.
But this one was like those we have experienced in the past.
Roland
Rather good today.
Roland
Very good again but carriers +/-5 kHz off centre became visible at the very end of my logging period.
Roland
Hi,
Perfect today for the 50 mins when I was logging.
regards
Bob
Great reception again.
Roland
Not perfect but not bad either.
Roland
Hi,
good, as usual.
Roland
Hi,
Perfect again - this is an excellent frequency for reception here.
regards
Bob
Hi all,
perfect results once again, see attachment
Simone
Hi,
Perfect again.
regards
Bob

Three hours with perfect signal and good audio! :cool:
Nevertheless: Looks like SNR is limited to 30dB at the moment?!
Very good and reliable.

Hello,
good reception today.
Hi,
reception was good apart from a TX interruption at 10:17 UTC, see screenshot.
Roland
Hi,
just a tiny bit of interference during moments of fading.
Roland
Hi all,
perfect decoding but it seemed they were only using a backup and not the regular datastream all day, so bitrate was lower and no data available (see also thread 7320 kHz)

Hi all,
A very good result for 50 mins, then interference started. Transmission ended 30 mins earlier.
John.
A lot of interference, mainly from a strong signal on 9465 kHz and an early end of transmission.
Roland
Rather good again.
Roland
A reliable service, at least at my usual listening time.
Roland
A bit weak with a strong interfering signal from CRI in Romanian on 9460 with a bandwidth of +/-10 kHz (as always).
Roland
Interference caused a few dropouts.
Roland
There was a short period with strange resyncs at good signal today, see screenshot.
Roland
Not totally perfect due to a bit of interference.
Roland
Again a bit of interference and sometimes fast and deep fading.

Driving from Bochum to Duisburg via A40 and A59.
The dropout is in the A40 tunnel in Essen.
The graph looks as if the SNR was limited.
