Simone
Pretty good results in the Swiss Alps using the DWT, I guess the two dips were a problem with my setup, sorry.
Simone
Bonnes vacances, Simone!
Currently in S-W of France until beginning of September. Thanks for your report from Swiss Alps
Before leaving Paris on last Thursday, I participated to a DRM+ presentation in Paris; I was happy to meet Gūnter Haug (SWR), Alex Zink and others ex-colleagues from DRM WG.
Regards.
Jacques
Simone, on which Alp are you stuck???? Davos? :p
Thanks Jacques,
great that you managed to meet Günter and some others again!
@Digger: Yes near Davos, (hope I got the coordinates right), easy to guess as they have a really nice (ultra)marathon up here this weekend.
Simone
Simone, your coordinates are pretty slap bang in the middle of Davos.
I noticed that the modulation disappeared at least once during the logging, but I was working with the PC at the same time, so a comparison would be interesting.
PS: I remember seeing that the signal was extremely weak around 1532.
Excellent results on the first transmission using the DWT here in the Swiss Alps.
Sorry no log from the second transmission here, but I had a look at the monitoring Rx near Frankfurt, which confirms a sync loss at 15:28 in addition to the usual small dips.
Simone
Almost perfect results for two hours today.
Simone

Bonsoir Jacques,
sorry, just noticed that myself, already corrected ;)
Thanks,
Simone
A problem on the first transmission, perfect results this afternoon.
Simone
... and for comparison a log of mobile reception this afternoon.

One break around 1250 I cannot account for (mute on).
Results from yesterday, also got the short break at 1250.
Simone
Quite good results today with only a few of these small dips.
Simone
A bit messy here. Must compare the Elektor with another setup to verify the reception.
One hour log with very good result ! Some problems here with rf-level input.
Great results for two hous today.
Simone
Perfect result today with a SNR-Peak at 39,23 dB ! :)

Simone
I used the SoDiRa for this part of the log. I cannot understand why it won't decode properly? I immediately switched to Dream, and the sound was back.
Oops, seems to be a TX problem; suddenly there was only the TX carrier around 1520 UTC...
Hello Terje,
What is SoDIRa receiver never heard about it.
Regards.
Jacques
Hello Terje,
What is SoDIRa receiver never heard about it.
Regards.
Jacques
Hi Jacques,
It is a Decoder Software. For this transmission I used it to decode 12 kHz from my Yaesu RX. It can also be used with the Elektor SDR, which I bought recently.
Btw, here is the rest of the TDP log, logged with Dream. The break around 1519 UT was definitely a DRM problem; the carrier wave remained on the air...
73
Terje
Nothing unusual noticed here, apart from the short problem at 15:19.
Simone
Perfect results on both transmissions today.
Simone
Short log. Perfect result here too for 29 Min. !
Unfortunately yes you are right my friend: AM transmission instead of DRM.
Back-up taken on an Alliss which was not DRM compatible (only 2 modified).
Regards / 73.
Jacques
Thanks Jacques for the explanation. It looks like there are still some problems as I cannot decode the signal which is on air right now with 22 dB. The SDC sign remains red in DREAM.
Edit: Now everything is fine again. :)
Edit 1302: And with some extra transmission without configuration today? :confused:
Problems on both transmissions today, started quite good on the afternoon transmission, but then problems occured again. Good results as usual in the last 15 minutes.
Simone
Thanks Simone and DRMDAB,
Simone, you know why from Ludo: tests on direct MDI feed from Belgium to Issoudun.
Regards.
Jacques
Hi all,
Aha, that explains the situation. The SDC lamp was red (at least some time before the break in the sound), but turned green during the last 15 minutes of the transmission.
Back to normal operation today, perfect results on both transmission.
@ Jacques: Yes I did know but don“t think the AM trannsmission on Thu was planned, but you already explained that, thanks ;)
Simone
Pretty good results again today.
Simone
Almost perfect here on the later transmission.

Hi all,
Although the signal was good there were a lot of decoding problems. With a lower BR, maybe, would be better.

Today, I tuned to TDPradio on 6015 at 15:00 to 16:00 and I've make a note of decoded audio frames and I calculated CDA for a given frames:
10000 - 91,18%
20000 - 89,03%
25000 - 89,34%
30000 - 87,9%
40000 - 88,73%
50000 - 85,68%
60000 - 84,37%
70000 - 85,97%
75000 - 86,21%
80000 - 84,70%
Maximum MER: 22,9 dB and minimum MER: 6,7 dB
On 2 November, it was 85,2% on first 25000 frames, then 77% on 50000 and finally 74,6% on 75000. Maximum MER: 23dB and minimum: 6dB, similar to today.
Good results today.
Simone
30 minutes of TDP - this meant 99% of CDA.
Seems different transmitters were used again for the two hours today, first hour perfect results, a few minor dips in the graph in the second hour.
Simone
Perfect results on the first transmission, only got the last 20 minutes this afternoon, a technical problem at my end, sorry.
Simone
A late start on the first transmission, a few minor dropouts on both transmissions today.
Simone
Good results today, slightly better on the first transmission.

Hi,
Excellent reception of TDP. Maybe not my 'bag of music' though.
Time: 13:37 until cd @ 13:59 UTC = 99.7 % CDA.

Hi all,
Although out of the target area the signal was about 50 dBuV but the high BR and low SNR didn't allow for better results.
Two major dropouts today.
Simone
Some problems especially in the second hour.
Simone
Quite good results on the first transmission apart from two dropouts, some more small dropouts this afternoon.

Simone
No such problems today, perfect results on the first transmission, only a few minor dropouts this afternoon.

Some problems at the start of the first transmission, DRM signal disappeared a few times, good results later, at 1330 it looked like an AM carrier on top causing the peak in signal strength but no impact on MER, almost perfect results this afternoon.
Simone
Pretty good results in both hours, only a few very small dips in the second hour, obviously using another transmitter.
Simone
Two dropouts at the start of the first transmission, after that perfect. Problems towards the end of the second transmission, at 1546 just a carrier for 3 minutes, later a quite weak signal.

Good reception. The driver signal is still visible when off air.
Quite good results apart from a weak signal in the last 20 minutes this afternoon.
Simone
Seemed there were some Tx problems at the strat of the first transmissions (no signal or AM carrier for some minutes).
Simone
Problems due to propagation this afternoon, logs from 2 locations, problems at the second one started 12 minutes later.
Simone
Pretty good results on the first transmission today, on the second transmission again a comparison of two locations, both showing a weaker period around 15:20, also bad propagation conditions in the last half hour.
Merry Christmas to Jacques, the colleagues at Issoudun and Ludo!
Simone
Still problems with propagation towards the end, otherwise quite good.

Good result, still too much feedthrough after the end of transmission:
Not very good during the last half hour. The log was unattended, so I have no explanation for the sudden loss of about everything just after 1540 UTC.
No propagation related problems here anymore, quite good results today, with a only few small dips in the afternoon log.

Perfect results on the first transmission, lots of breaks in the afternoon and even when there was a signal and decoding was OK there was no audio signal, just silence.
Simone
Seems there were no transmissions today?
Simone
As of Wednesday 10 February, transmissions will restart with some light
changes in content and schedule (1 hour earlier):
- "slipping time" transmission will be from 0700 to 1400 UTC from
Monday to Sunday and programme will be called "TDPRadio",
- "fixed time" transmission will be all days from 1400 to 1500
UTC and programme will be called "The Disco Palace".
In all cases, Alliss (Nil or Mississipi) will be used with 60 kW RMS and
2 / 2 antenna at 60°.
Please continue to use this existing thread for results and comments of TDPradio transmissions, for "The Disco Palace" please use this (http://www.drmrx.org/forum/showthread.php?t=2184) new thread.
Thanks to Ludo and Jacques for the details.
Simone
Perfect results this morning.
Simone
Perfect results again today.
Simone
A weak signal around 1130, probably due to bad propagation, as I also noticed problems on other frequencies at the same time.
Simone
It was an M8.9 solar flare; it killed my log of BR5 at the same time!
