Hi all
This is my results from RTL2 - 5590 kHz
Good results until 20:00 when no start other station...
Hi all
After the 20:00 hours I have two AM Station on 5585kHz and 5595 kHz and the DRM disappeared...
Hi all,
a great start this morning, but then the usual results, see attachment

Hi all
my today results from RTL2..
Hi all
my today report from RTL2..it´s good until 18:05.
Solid here until 22h48 where snr falls down, probably because of QRM.

RX was on its batteries. PC had charger ON.
Solid until 6h58 where QRM starts on 5985 R Vlaanderen Int.
Until 6h38 my Sangean has the power supply on, then
batteries only which highly improves the SNR.

Hi Michel
it would be interesting to see what happens with a higher bitrate, maybe one day next week with some notice I will log it for you.
Many thanks

Hi all
the reception signal is every day good but they exist time where I have interferencias of the adjacent stations then low SNR
Hi,
here's a full 18 hours log of 5990 kHz at my home QTH. Maximum Signal strength is abt S9+30db in the afternoon. However, interferences are also detectable at this short distance (pure skywave propagation).
We installed the same automatic DRM mode changes as on 6095 kHz, I hope this ensures a better audio quality during daytime and a more robust reception during the more difficult periods.
73 Michel
Hi all,
quite good, except a bad period at 0700-0725 this morning, see attachment

Hi folks,
Here is my report from RTL 5990 kHz yesterday. Started off very well but toward the end adjacent channel interference took over.

Hi all
my today report from RTL2
Hi,
This is my result from RTL2 this morning.
I started listening at 06:30, when reception was very good. But at around 7 it became worse. Total after 3 hours is just 35 % correct audio.
73's Per - SM0ITS
Hi all,
here is my 10.5 hours log from today
73, Simone
Good reception at my location too. Max SNR even jumped up to 29dB.
73 Michel
Hi,
From 18 - 20 UTC, enclosed find my result.
On the 6095 thread CT1ADT at Sines wrote "For my location the frequency of 5990 kHz is better that 6095 kHz... reason?"
I can only agree and put the same question.
73's Per - SM0ITS
Hi all
J´aime pas RTL2 avec 16-QAM - 14,5 kbit/s
Hi,
Todays reception between 14:40 and 16:50. It was some big changes in SNR, 4 to 24 dB.
73's Per - SM0ITS
Hi,
Todays listening was between 16 and 18 UTC. I noticed the text message indicating reduced bitrate at 17:55:
1555 - 1755 UTC : 64-QAM - 17,4 kbit/s
1755 - 0000 UTC : 16-QAM - 14,5 kbit/s
The Tx went off at 17:55 not to return?
Anyway, the last hour produced excellent reception, hence no need to reduce bitrate at that time.
73's Per - SM0ITS
Hi,
This is my result this morning from RTL2.
The big drop at 06:55 is when the change of bitrate accour.
At the same time an AM station starts on 5985 kHz, which completely ruins the DRM transmission of RTL when it re-starts a few minutes later!
73's Per - SM0ITS
Hi,
Today's listening is from 16:00 until 18:00 UTC. The change over of bitrate and modulation, at 17:55, was just a 15 seconds break.
The first hour: 84% correct audio.
Second hour: 98 % correct audio.

Can be detected in Jakarta, Indonesia. Screenshot attached.
Hi,
we will proceed today to the same modifications on the 5990 kHz transmitter than we did last week on the 6095 kHz transmitter. DRM broadcasts will hopefully restart this afternoon.

I was about 3 weeks on holiday. When I returned on Sunday, 24 May of 2004, I realized, that RTL 6095 can not be received any more, but RTL 5990 still worked. RTL 6095 kHZ has only between 10 and 15 dB SNR the whole day, so that only during that time when RTL uses 16-QAM - 14,5 kbit/s the signal can be decoded. Signals coded with 64 QAM- 20.9 kBit or 17 kBit/s can not be decoded any more.
I tried several antennas: Magnetic Loop, long wire, with no success.
My dates: Place: Münster in Westfalen/Germany, 51°58' N, 7°38'E
Receiver: modified Yaesu FRG 100 and "Sat-Schneider" mixer module
PC: Intel P4 2GHz with DRM-Softwareradio.
Now I read that RTL modified its antennas of the 6095 kHz station and the antenna of the 5990 will be modified by the same way. Did this modification cause that the "Dead Zone" became larger? Or did RTL reduce the gain of the antennas or did RTL modify the diagram of their antennas? Will RTL 5990 also dissappear too in the near future?
From Colombo 20.06.04
Hi all,
amazing how the RTL DRM signal manages to substain
the severe noise level in the 49 m-band here in Asia.
I could detect both RTL signals: ( 5990 and 6095 ) khz.
But the 6095 khz was hopeless covered with stróng local
AM signals. Not so the 5990 khz.
At times bids and pieces of Audio got through on this freq.

Hi,
This is my result this morning, at 06:05 until 07:15. Do note the dramatic drop in readability at 06:55, when the bitrate was changed. The last 20 minutes gives just a 27 % correct decoded audio. Compared with 99.6 % for the first part!
73's Per - SM0ITS
Hi,
This time a later reception of RTL2, 19:45 - 21:10 UTC. It's interesting to note there is no interference from DW @ 5980 when they start at 21 UTC.
73's Per - SM0ITS
Hi,
I gave RTL2 a try this morning, 06:45 until fade out at 07:30. Big variations in both SNR and readability.
Dear all,
during the next two weeks, some important maintenance works are carried out at RTL's transmitter sites Junglinster and Beidweiler. That's why our daily DRM transmissions on 5990 kHz will only start at 1400UTC. At the same time, the old analogue control interface of the 6095 kHz transmitter will be entirely replaced by a modern microcomputer-based remotecontrol system. As this is a major intervention, DRM transmissions on 6095 kHz will be interrupted for about two weeks.
Best Regards,
Michel

Although the signal of RTL 5990 is very strong, the two (!)interferences caused, that the average S/N was lower than 8 dB. Therefore the DRM signal could not be decoded any more, although only 16 QAM is used. The new bandpass in the Dream Software (last CVS) does not help, the interferers are too strong. The DRM software does not decode too.
Measuring time: Time: 21:00 until 21:30 UTC, 08.08.2004, Location Münster /Westfalen in Germany, S/N newer higher than 10 dB, therefore no logfile, does not make any sense.
If you want to hear, how strong the interferers are:
Please listen to the record of the interferer at 5985kHz. This server does not allow to upload mp3-files, therefore I had to zip it.

And hier the second soundfile of the interferer RTL 5990kHz: (5990+5Khz). I tried to turn my magnetic loop, that the interferers became as weak as possible (or should I write impossible :confused: ? )
Hi all,
I am currently listening to RTL2 on 5990 kHz and I don't think that it sounds good.
There is TOO MUCH COMPRESSION on this signal.
Have a listen, what do you think?
Also compare to DW Wertachtal on 5975 kHz which uses a lower bitrate, but which sounds much better.

Hi DRMs,
annother test. Not bad for this cheap DRM -equipment..

Hi,
It's almost two months ago since I last time gave RTL 2 a try. Today it was quite good reception between 15:09 and 16:34 UTC. Result: 94 %.
I was getting good reception this morning in stereo is this the only time of day they use stereo mode ?
30 minutes of poor audio was decodable from 06:00 UTC on 5990 kHz here today.
RTL 6095 kHz and DW on 5975 kHz were also present, but 5990 was the only one good enough to decode.
Cheers, Chris
(The graph only shows the first few minutes).
A very strong signal from RTL on 5990 kHz around 06:00 UTC yesterday (September 25), but it was joined by a very strong AM signal from Spain on 5985 kHz :-(
Not a good combination for decoding DRM.
Cheers, Chris
Hi All
At last the signal peaked up nicely around 06:00 allowing a few minutes of good decoding.
Please excuse the long lead-in time on the graph - I had to start things remotely today.
Cheers, Chris
Good reception for a few minutes today.
What's the email address they advertise for reception reports? I thought I'd got a screen capture of it, but I got every other message except that one I think!
Cheers, Chris

The message window shows:
"Please do not hesitate to send your reception reports to: drm@rtl.com" and "Please attach DRM software log files to your reception reports".
I would also mention in the report, that they are transmitting badly dynamically compressed audio.

Hi All
RTL 2 audio was better than the graph would indicate for the news at 06:00. The signal fades rapidly after that though.

Surprising reception here today. Subsequently thought that the transmitter went berserk but it might have been an AM transmitter tuning up on freq.

A strong carrier on the center frequency, is this what's causing the bad result?

Hi Per
RTL seem to have a problem with 5990 & 6095 there is too much interferance not worth listening too anymore which is a shame, they need better frequencies, in the summmer they were almost perfect, if drm is the future I would rather stick with analouge,

RTL on 6095 seems to be off the air today although 5990 is ok. Seasonable propagation will be an issue. At the moment RTL's audio drops out quite frequently compared to the summer months when reception throughout the main part of the day was reliable. Skip may be lengthening a little due to coming into winter. It would be interesting to see if anyone in Ireland or the West of England, is having better reception.

Caught some audio here tonight but conditions petered out with interference from both upper and lower adjacent frequencies.

Only snippets of frenzied music tonight while getting pretty solid, easy listening from DW on 3995. Possibly the bit rate 14.56 vs 10.84 kbps makes the difference.

Hello,
The audio quality of this transmission left a lot to be desired. I did not measure the frequncy response but I would estimate it was around 200 HZ to about 5 KHZ. It sounded like it began dropping around 200 HZ at a 6 db rate on down. I thought I would mention it. I liked the music though. Here is the report.

Hi all,
2-hour listening this morning. Quite good results for this station. Some problems with high processor load only (I did some calculations whilst listening).
But I have to mention that usually listing is only possible in the morning. Usually very bad signal in the afternoons and evenings (strong interferencies from AM stations).
They should change the frequency or make some agreements with others broadcasters. Same for 6095 kHz.

The debat has been ongoing for some about frequency changes but RTL do not respond, DW do respond and make changes.

Hi,
Frequency planning?
Today at 14:40 UTC there are three (3) AM carriers interfering with RTL. A Russian (?) station on the center freq. and 2 other stations +/- 5 kHz! SNR at 8-10 dB, so no audio. See screen shot.
Hi,
With reference to my post above, I also tried listening to RTL at 19:00 UTC.
Not a trace of any DRM signal! But a strong AM signal, which identified it self as RAI Int. A look at their home page:
Target EAST EUROPE
18.10 18.25 5990 Czech *
18.25 18.40 5990 Slovak *
18.40 19.00 5990 Polish *

Hi,
during the next two weeks, we will start SFN (Single Frequency Network) tests on 5990 kHz. During daytime, RTL France DRM transmissions will be broadcast simultaneously from Junglinster and Jülich towards France. Optimizing the network parameters will be one of the major tasks during the test period. The SFN schedule will be:
21/6/2005: 08:00 UTC - 18:00 UTC
22/6/2005: 05:00 UTC - 18:00 UTC
23/6/2005: 05:00 UTC - 18:00 UTC
24/6/2005: 08:00 UTC - 18:00 UTC
28/6/2005: 08:00 UTC - 18:00 UTC
29/6/2005: 05:00 UTC - 18:00 UTC
30/6/2005: 05:00 UTC - 18:00 UTC

Hi
todays results were better than usual. Perhaps my finetuning on the antanna helped a little bit.
Is it possible that time schedules have changed? When I switched on my receiver just before 17:00 UTC RTL was "invisible" (also on 6095 while adjacent B5 came in with the usual low 21 dB).
On 5990 I could hear an AM broadcast in an (for me) unknown language, perhaps AIR from India, until the sudden appearance of the DRM signal from Junglinster

Reception from 2230-2250 on 26-Dec-2005. SNR varied between 7.5 and 16 dB. Sporadic audio from about 2240 as local sunset approached.
Editorial aside (I know that North America isn't your target audience): Why does RTL choose such rotten frequencies that are unreceivable in North America? Even back in the 1960's and early 1970's, 6090 was virtually unreceivable in North America. Now, you guys choose 6095 which is blasted over by that religious charlatan Gene Scott from Costa Rica! Any chance of using 41 meters for English during North America's evening hours?

Why should a commercial radio station like RTL choose a frequency such that their programme could be received outside of but not within a large part of its target area? :confused:

Superb results this morning (21-Jan-2006) with no-dropouts reception at 0748 UTC. SNR ranging from 15.6 to 18.5 dB from home QTH at Detroit, MI USA using DRM Software Radio connected to a TenTec RX-350 receiver.
Dear all,
in order to improve reception during the moring hours, RTL is currently transmitting in SFN mode from 8:00UTC to 9:50UTC (9:27UTC on the weekend). Involved transmitters are the transmitters of BCE in Junglinster and Deutsche Welle in Sines. Synchronisation has been adjusted to cover France in an optimal way. The SFN tests are scheduled to run for a few weeks.
Regards,
Michel
Hi Michel,
stable signal about S9+ 20 this morning also before and after the transmission form Sines, here is a typical example of the IR (at 0900 UTC).
Simone
Hi Michel,
at 8 UTC there was no synchronisation possible with Dream, but strong signal level. Then again perfect reception, like before.
...and it looks more like 2 transmitters from 1000 UTC, see attachment
Simone
Hi Michel,
from my results (decoding, IR and signal strength) I cannot tell when Sines was transmitting, I had good results before and after the times that you mentioned, so at least things did not get worse with the SFN ;)
Also sync problems at 0800, using DRMSWR.
Simone
Hi,
for organisational reasons we decided not to transmit in SFN on the weekends. SFN operation will resume monday morning.
Regards,
Michel
Hi,
Even if there was no SFN today excellent near perfect reception 13:28 - 15:42.
regards
Bob
Hi Michel,
I havn´t seen morning reports on RTL´s transmissions from France lately, but for Germany an SFN with a transmission from Sines before 0800 would be more interesting (same on 6095 kHZ) as we already get a good signal at 0800, see also today´s report on 6095 kHz.
Simone
Hello to all,
Good reception this morning after 9:40 UTC. Before 9:25 there were local QRM sources I eliminated.
Report done on a laptop running with batteries only.

Hi Michel
I think that part of the problem is the connection between RTL and Sines. In the last days it seem working more or less...But is the net delay stable? I`m not working at the moment during the SFN test, but I have noticed that the system working with net delay between 400 and 500 ms, but some times this go up to 700, or under 300, and maybe loss synchronism. I waiting for SAT connection. I`m shure that will be most beter.

An unattended log from today.
Paul
Hello to all,
A short log to show SNR decreasing during the 6pm news. It happens later and later during the season, and now I can even listen when the audio switches to 14,56kbps (now before the 6pm news, in the summer at 9:30pm).
Just a thing I will verify regularly : 14kbps even without SBR sounds better on RTL (France) than 17kbps with SBR. The 17kbps sound is sometimes unpleasant to hear (encoding artefacts ?) and the sound levels between show hosts / live calls / music / commercial are too different. I have to change regularly the level of soundcard/DWT to keep a pleasant and constant listening. This doesn't happen with the 14kbps which has -IMO- a pleasant soft sound.
73, de Stephane
Hi all,
a few dropouts this morning, is the SFN test still running?
Simone
Hi all,
maybe Sines started at 0725 this morning on this frequency?
Simone
Hi Simone,
normally the SFN operation period came to an end on last wednsday, so it's either propagation related or perhaps man-made-noise related. Another explanation could have been an adjustement on the transmitter, but I actually have no feedback on this action.
Regards,
Michel
Hi Michel,
similar results as yesterday, again a sync loss at 0725, but I did not watch it
Simone
I will monitor the signal locally when I'm back from China.
Regards,
Michel
Hi Michel,
concerning the sync loss at 0725, that´s probably the configuration change.
Simone
Dear all,
we will perform a software update on the DRM multiplexer this afternoon. Transmissions on 5990 kHz will be interrupted from about 1100UTC to 1400UTC.
Regards,
Michel
Hello to all,
Perfect during "Les Grosses Tetes" and the 18hrs news. Then, sunset... The "Classique d'Or" music title was very undermodulated compared to the talked programme. It is the same problem, but with less proportions, than on the 17,4kbps stream.
I noticed it very well this morning during "Stop ou Encore" when show host Vincent Perrot, live from the yearly Agriculture Showcase in Paris, announced a title. We could hear the title starting at a high level while he was talking, but then the feed from the show was cut and the title went on with a much lower level... These modulation/sound level differences often make RTL France's DRM listening uncomfortable.
73, de Stephane
Hello to all,
Very good, and surprisingly much later than usually. That can be explained by propagation and/or not much (electrical) activity in the neighborough.
Still modulation problems in the 17,4kbps stream... Today, music in "Les Grosses Têtes" was sometimes much louder than talk. Nothing much to complain with the 14,5kbps stream, except sound level changing gradually from time to time during the 6pm news.
73, de Stephane
Hello to all,
Today good results with 20,96kbps parametric stereo stream and 17,46kbps mono. But with the 20,96kbps stream there is :
- a problem in SDC decoding (yellow mark using DReaM),
- no associated text decoding.
Many dropouts this morning, but very good SNR, up to 28dB.
73, de Stephane
Hi,
we finally managed to finish the software updates today although a few adjustements have to be done in the next days (such as analzing the SDC CRC / AFC problem which however does not occur on earlier DREAM versions).
Regards,
Michel
(such as analzing the SDC CRC / AFC problem which however does not occur on earlier DREAM versions).
Hi Michel,
that´s normal as this feature was only implemented not too long ago (last May or so?), but the yellow SDC indicator means the CRC is OK, but there is incorrect data in the SDC.
Simone
Hello to all,
Good results today in stereo, but only with the laptop running on batteries only. After 1500 UT I listened again, there was the 17,46kbps mono stream again. But there was a new feed of the lastest headlines as attached text. 20 seconds for each of the 10 headlines repeatedly (cf. screen capture). Signal was very stable with 25dB SNR until 1530 UT.
73, de Stephane
Hello to all,
Perfect tonight during 'Studio 22' pop show, with guest singer Cali and also Dionysos. And worth listening with the 17kbps stream, thanks to BCE team ! (as the german service was already running 14kbps only at this time)
News headlines text was updated, with station's tips about the news programmes aired live from the Agriculture Showcase.
'Sunset' effect after the 7pm news.
73, de Stephane
An above average reception here today and very few drop-outs.
Signal breakdown after 17:43 UTC (3/4 hrs. after local sunset).
Sorry I didn't cross-check with 6095 kHz (the SNR of which is normally higher), and yes, the yellow SDC lamp is still on.

Ok, so there has been work in progress at Junglinster, but why have I been hearing a (400ms?) echo, intermittently for the past few days? I don't understand how it could be a fault at the receiver end. I attach a screenshot, and a zipped mp3
AND another thing - is it really a good idea to have _every_ post concerning RTL 5990 under the sole rubric "RTL 5990 kHz"? Surely, there should be a FORUM under this heading, not a thread - or should we perhaps do away with all separate threads, and just post everything under "DRM" 8-[

RTL 5990 was fine this morning, now it's echoing again (14:00utc) - is it just me, or do others hear this? - I've never heard this on any other DRM tx

Where is the problem? There are a lot of other DRM transmissions apart from this one. If we were to establish a forum for each one of them, this whole website would look rather chaotic. The way it is, every interested party can find the information at a single place and this is sufficient.

Hi,
I know the French like talking a lot, but this is ridicoulous! :D
Errr. was... The "echo" problem disappeared 0713 UT during writing this, when there was a short break in the DRM signal. Obviously, someone is aware of the problem.

PS: Around 0930 UT I added a log which started during the "echo" transmission. The break can be seen in the log. The rest of the logging was fine without any echoes.

Hello to all,
Perfect today during 'Les Grosses Têtes' and the 6pm news, except maybe some trouble around 16:20 UT while working with Word on the computer. Then the signal faded away at 17:52 UT. Detail of the 'sunset' also attached.
73, de Stephane
Hi all,
quite good, but two very weak periods within six hours today.
Hello to all,
My logs will follow the one from Carsten, at around the same distance of Junglinster Txs.
Until 15:40 UT, no problem, in 20kbps stereo, then dropped. I searched for another programme to listen to. Back listening at 16:20 UT in 17kbps mono, it stayed almost perfect until the headlines of the 7pm news (18:03 UT) and I let Dream logging to get the total fadeaway of the signal.

Driving from 48147 Muenster to 46712 Gescher via A1, A43, B525:
Hello to all,
Excellent, as ever, during 'Les grosses têtes' and the 6pm news. I noticed the switch from stereo to mono stream at 15:15 UT yesterday. At 1900 UT, Norton AV started a check-up on my computer as a weekly task, that ruined the reception :-) But one can see the radiowave sunset at 1913 (local sunset is at 1745 UT),
A few remarks (see screenshot attached) :
- in the rolling 80bps text, one of the news headlines contained the title of a book between 'EM' source code signs (source code not decoded by Dream nor DWT software),
- in the AFS, frequencies are displayed as 'sunday only' in the days column,
- also in the AFS, since yesterday, the 25805 kHz frequency is shown. Could someone from the BCE say more about this ? Maybe some local service in Luxembourg, like 25795 (25805 wasn't displayed in the A06 DRM registrations on the HFCC website).
73, de Stephane
Hello to all,
A long log through the whole day to show global reception here in the centre of Alsace. Long to start in the morning, and due to stereo stream, reception is not possible with this SNR. Frequency is always better after 1400 UT (98% between 1530 and 'sunset' at 2014 UT) but now, after DST switching, that is only the last 30 minutes of 'Les Grosses Têtes' which are comfortable to hear :-).
Since a week or more, there is a major improvement in the audio feed : there is no more this awful difference in sound dynamic between talk in studio, music, commercials and jingles. Very nice ! And the 14,56kbps AAC+SBR at nighttime is really a top, compared to the horrible stream -without- SBR at the Deutsche Welle.
73, de Stephane
Hello to all,
98% audio between 1530 and 1900 UT. It is the right window here for 5990 in spring.
There's again dynamic variation in the audio stream, though I could hear today that the sound was brutally lowered during the commercials when it was too high :-) .
73, de Stephane
hello to all,
Here's a log for 1415 - 1700 UT, while I was editing slides and negatives on a lightbox with fluorescent bulbs and AC adaptor next to the computer and the DWT. Resulting was a quick and regular fading, causing many short dropouts (+/- 5 to 8 dB in SNR every 20 seconds). I reached almost 93 % audio. The dropouts were only bad to follow the news, of course.
Propagation is not involved. I got 80 minutes at 21dB SNR with 100% audio on 6095 kHz just after I turned the lightbox off.

5990 will be switched off for antenna maintenance at 12 h 15 until 15h 15

Hello to all,
A log through the whole day (except a 1445-1600 UTC window). For explanations about the reception conditions, see my post for TDF 3965. All I have to say is that in that place, reception profile is the same as in Alsace (good only between 'Les Grosses Têtes' and now the 10pm news). During the day, heavy QRM due to local powerline makes reception impossible to reach with the laptop running on batteries only, though that is possible with only a few drop-outs in the audio, when I am in Alsace in a QRM-free house.
By the way, this place 85km north from Paris is very good for all-year VHF reception from the north-east (RTBF site Léglise FM 91,5 and 87,6 and also FM 92,5 RTL Radio Letzbg pass through local stations on the same frequency, with a directionnal antenna).
73, de Stephane
hello to all,
Nice log today, from 'Les Grosses Têtes' to Isabelle Quenin's talk programme with a former stuntman from the Mario Lurashi's team (horse dressage, doing a great job at the Europa-Park in Rust btw :-D ).
Until the 6pm news, the UEP stream (19kbps parametric stereo) saves a lot with the short dropouts and makes a difference in comfort of listening with the mono 17kbps EEP stream later in the evening.
From 1900 to 2100 UT, interference from this source on 5985 kHz :
5985 1900 2100 52S,53W BEI 500 257 CHN CRI RTC (from HFCC data)
A carrier is really visible on the spectrum (see second picture), the signal is a broadcast from Beijing towards southwest. It causes severe damage to 5990 though a good SNR : listening is -really- not possible (maybe trying 14kbps and/or UEP during this time slot would be okay).
After 2100 again nice conditions, until the signal faded away at 2125 UT.
Result of today :
1450-1600 22,0dB 97,2% audio
1600-1900 24,5dB 99,7%
1900-2100 21,2dB 92,0%
2101-2125 23,6dB 100%
73, de Stephane
...and here is a daytime log. Never mind the smaller dropouts, these are most probably caused by local manmade noise.
As I wasn't at home at noon I can't tell you, what happened betweeen 11:00 and 12:30 - interference from another Tx or signal simply too low (i.e. too near to the critical level of 20 dB SNR where below dropouts can occur)?
I'll restart DREAM now and look, what happens in the evening.
Yes, I can confirm the trouble caused by an unknown service on 5985 kHz in the evening.
After the night signal comes back strong, but not yet stable the moment I am writing this. Also I have the strong impression a high voltage line some 100 m from my appartment has a negative influence when it is wet (Oh yes, we have the usual grey and rainy sky here this morning :( )
A strong signal but also two dropouts as a result from interference.
I was amazed to hear a political discussion programme on this commercial station, a kind of programme one is not used to hear on german language commercial stations where there is mostly chart rotation ("best hits", "greatest hits", "greatest hits of all times" etc.) instead.

Hello to all,
That explains why I couldn't tune to 'Les Grosses Têtes' at 1430 UT today, while 6095 was running well. I'm not sure there was DRM noise on 5990 at a very low level at this time of the day, hard to say with my Sony receiver, and nothing on the 'scopes' of DWT/Dream. I listened to DW DRM instead.
Very good reception indeed during the 6pm news : on my log, the lower SNR between 1636-1651 UT was due to swtching my computer on AC power.
Stream switched from stereo to mono at 1700 and later, signal faded away totally at 2137 UT.

RTL is surprisingly good here this morning... Long time I didn't try 5990 in the morning as reception is 'lightly possible' after 1000 UT and simply 'good' between 1600 and 2200 UT now (with some interference problems at 1900-2100).
SNR at 0720 UT was 27dB and very stable while 6095 was only 11dB, which is usually the same for 5990 at this time of the day.

Hello to all,
RTL seemed to be transmitting all through the night with 20,96kbps EEP and parametric stereo stream. Signal was stable at around 9-10 dB SNR here, not enough to get any audio.
By the way, recently they were in p-stereo 20kbps in UEP on daytime, mono 17kbps evening (after 17 UT) and maybe night too (I cannot say after 22 UT). On afternoons I also noticed p-stereo 19,08kbps, I am not sure but maybe p-stereo 17kbps was used too (I often listen in the 14-17 UT range but I don't log). So, there are many bitrate tests during this spring.
Oh, little off-topic, but as seen on RTL DRM newstext (see screenshot), a sad news : RTL show host Max Meynier died on tuesday, he was 68. He was on air during the 70s and 80s with his famous evening programme for truck drivers (RTL is popular among truckers with the 234 longwave). He was also on RTL in the early 90s for summer game shows, as far as I remember. A tribute to him will be broadcast this wednesday night after 2000 UT, with night show host Georges Lang.

Hi all,
A very good result until 05H00, then the signal started to turn weak and affected the result.

Surprisingly superb reception of RTL French Service on 5990 kHz at 0400 on 21-Oct-2006 in Detroit, Michigan USA. Usually, I can get a lock on this frequency, but not audio. This evening, audio was perfect.
If RTL would just send a little more power out on 5990, we'd get regular reception in North America during our evenings!!! :)
Receiver: TenTec RX-350
Antenna: Butternut 80/40 metre vertical ham antenna
Software: DREAM
Average SN/R: 13.8 dB
Réception de nuit à Paris.
