Hi,

Just spotted TDF on 11845 kHz, however the Channel Impulse response now at 0825 UTC is very diffuse.

Salut Jacques and all.

Her short log from RFI on 11845Khz .

Very problem for AM on 11850Khz and deep QSB . Splatter from LSB from 11850Khz

:confused:

Hi,

With a lot off effort I get the occasional sound burst, but the QRM from Albania +10 kHz is too bad.

It got "better" when the splatter from 11.855 MHz stopped, but it seems, Jacques, you shoot over my QTH... :confused:

Hi Sixten, Digger and all,

Thanks for your reports; this transmission is intended to cover Tunisia as there is an ASBU conference in Tunis on 20, 21 and 22 November between 0900 and 1400 UTC; main beam at 144° so you are taking the rear lobe (-20 dB).

Regards / 73.

A noter que pour la premiére fois (a ma connaissance) c'est RFI et non plus TDF qui s'affiche...

Hi all,

First report on this frequency. A very good result until QRM started (~1413). The signal reached 45 dBuV and the sound is good. Look at the two pngs, the results, Label, Impulse response and QRM.

Hi,

I seem to be either too near the TX or sitting at 90 deg angle from Issoudun is not optimum for this site. :confused:

Hi All

Faint signs of 11845 kHz around 11845 kHz here last night. I didn't expect this signal to appear here at all.

Cheers, Chris

Hello to all,

Short try after 1300 UT, on my Sony ICF SW7600G there was a clear DRM signal besides AM on 11850, but on the DWT almost nothing appeared : mostly QRN from ceramic heaters around, or anything... DRM will be ruined here from time to time until next march-april now. I wonder how Digital Radio receivers react to these interferences. It is a main problem for DRM use by non-DXers in my opinion.

Hi Sixten, Terje, Daniel, John (in Grece), Chris in New Zealand and Stephane,

Thanks for your reports; the antenna in use was a 3/4/0.5 at 144 ° so it is quite normal that reception was fine in Greece; from my simulation, signal in athens was -10 db (45 dBµV/m) compared to reception in Tunis. Anyway, thank you John for valuable report. Thanks also to Chris in ZL for DX trial.

Reception not bad in Noerthern Europe (abour 30 dBµV/m); OK with a good antenna....

Our transmission is over now.

Regards / 73
