This night i have receive of 177 Khz DKULTURE DRM Mono strong signal of long wire antenna SNR : 15 to 25 db .
I see two picture to MOT slid show mode is problem picture no constant of screen only one second no comprehend, audio is back to I clic of "wir über uns" no audio, Nachrichten Journaline is OK.

Almost perfect results last night.

Great results again last night.

Perfect reception here for almost two hours. 99.99 % CDA from 0004 - 0157 UTC.
Perfect results again last night.

One small dip last night, otherwise perfect.

Reception at Paris.
At 1h55 start of transmiter of Europe 1 on 183 kHz.
Daniel
After 02 UTC the reception (at least when using an omnidirectional antenna) is not possible.
Pretty good results last night.
Simone
Only about 70% decoded audio last night in this unattended log.
Reception near Moscow. 95% on AR-7030 + ferrite rod 200 mm

Lower SNR than usual at the start of my log but not causing a problem for decoding.

Hello togeher,
here is a plot from last night - at 2:59 h RFI starts to transmit on 183 kHz and from this moment on there is no reception possible, because of the half channel "overlap".
Greetings Jürgen
Exactly the same situation in Switzerland! With France transmitting - no reception of DKULTUR. 99.9% decoded audio between 0110 - 0257 UTC.
It would be interesting to set up a directional antenna and null out France.

The loop antenna helps to suppress interference from 183 kHz:
I don't understand what happened last night. :confused:

I don't understand what happened last night. :confused:
My loop took up all the energy, nothing left for you! :D :D :D
Mean, it looks like Fritz fired up his nasty loop again around 2 UTC last night. :p
As I was sound asleep, I have no explanation for the miserable reception.
More or less the same result last night, only that the proportions audio / no audio have changed a little compared to the previous log.
Another unattended log with 61% CDA.
A test with a ferrite antenna tuned to 177 kHz and directed to minimize interference from France (which is not easy). Around 70% decoded audio between 01 and 03 UTC.
A log using the omnidirectional, active antenna. Surprisingly good reception.
Perfect results last night.

Perfect for two hours from midnight until 01:59 UTC with 99.7% CDA. No reception at all after 02:25.
Almost perfect for two hours from midnight until 01:59 UTC with 99.00% CDA and 85.00% CDA up until 02:26. No reception at all after 02:26.
Modified my active antenna yesterday, but the result was disappointing. Need to check with the original circuit tonight again.
Not quite original, but another test with a slightly different antenna design. But definitely better than the last log. Will try again with the original configuration again tonight.
Don't ask! I have no idea what went wrong.
Back to the original circuit for the active antenna, but this log was not very good.
Last night's result was a bit better.
Perfect results last night.
Simone

About 80% CDA in this 2 hours long log.

Seems there was a short break in transmission last night, otherwise perfect results again.
Simone
Perfect results last night and EPG has been updated.

Not perfect, but quite good. DRM started at 0100 UTC. I set my DRM Plotter to end at 0300.
Almost perfect results last night.
Simone
Perfect results last night.

Very good reception in this log for almost the entire hour. I made a mistake and set the DRM-Plotter to shut down the PC at 0200 instead of 0300 UTC.
Good results again last night.
Simone
Indeed, very good reception during the night.
Perfect results last night.

Excellent at 31 db SNR av. until Europe1 starts on 183 kHz.
Short log 15min . very strong signal. Perfect reciotion.
Perfect results last night.
