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:

Mean, it looks like Fritz fired up his nasty loop again around 2 UTC last night.
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.

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.
