HI Simone, James and other friends,

DRM to HFCC Tunis
Hi Sixteen,

Antenna direction is not good for you but nice to know that transmitter is:) on air.

Well, Jacques, we here in the North presumably like TDF so much that we still try to keep listening (especially if we dont have to listen to TDPRadio trance any more). :)

Good SNR, perfect reception here at the moment. It is just too bad, for me, too, that I cannot be listening somewhere in the warmth of Tunis.

Thank you Ager.

Thank you Ager.

Sorry for my too short previous message...:o

I had another look to your very interesting reports (with audio files) sent during transmissions to Finland some days ago. Now, you are in a less than optimal situation I agree.

I am no more working for TDF being something like pre-retired (or "early retirrment") but still in close contact with my friends there and keeping on supporting DRM.

Hi Jacques and all,

Good to see you back in the Forum again, Jacques. I am not really in the target area either, and like previous transmissions from ISS towards Africa, it is not optimum for my QTH. However, the 2nd transmission was better than the first.

Btw, the IR was very messy here with up to 12 peaks visible...

I didn't listen too closely, but TDP went silent just before 09 UTC, then about 20 minutes later the music started again. Around 0927 UT suddenly the language changed to French.

Hi Jacques and all.

Perfect DRM propagtion this time strong and stabile, but only 2min music from this 1h 54min. transmission .:rolleyes:

Hi all,

I received this transmission today with a very good signal (40 - 60 dBuV). I was expecting a higher SNR figure...

It started with no audio for a while and at 20.96 kbps BR/P stereo and TPDradio label. Then, music started. The sound was good (~13 kHz BW) as well as the IR. I was monitoring until 08:45 then I left it unattended to the end of both transmissions. Sometime (?) the label changed to TDF-RFI and 18.28 kbps BR/ mono. Find attached the results.

Ager 02-02-2009 13:46

Jacques, I too, hope to read more from you, now onwards!
Yes, I seem to be in a worse position in this test here in the North. I guess I received much less that Sixten. There were several breaks in both transmissions. Anyway, much and long sequencies were quite listenable.

Previous TDF/CRI tests brought just perfect results here.

I guess, am normally a little aside from target areas, but anyway with lots of good daily receiving opportunities. So DRM listening is not going to loose its fascination.

Digger 02-02-2009 18:45

5865 became 5875, and BBC on that frequency at 19:45 UT is 40 dB stronger than the DRM signal ... :confused:

Hi all,

Impossible to be received due to strong co-channel QRM.

Hi all.

Good signal stringt from start but bad DRM propagtion and BBC 500Kw strong give influence . 2000UTC BBC QRT now better reciption . Signal stringth up to 74dbuV 2030UTC . Perfect last 40min.

All times are GMT. The time now is 10:17.
