Last Saturday I reported that I suffered from strong BC QRM centered on DCF39. I ascribed that to the Luxemburg effect.

But in the meantime I found out that this was not the cause of the trouble. Apparently some non-linear effect has developed in the transmit/receive circuitry of the transmitter.
The transmitter was built by Harry, PA0LQ and I will ask him to investigate the matter.

Most of the audio on DCF39 came from the BBC World Service.
And so DCF39 carried a report on the Wimbledon final between the Williams sisters. Actually more interesting than its own "programme"...
