Longwave AM TX closing in Germany

Stefan DK7FC recently posted this to the RSGB LF group:
Hi LF,

Obviously there was a decision that DLF (Deutschlandfunk) will go QRT on LF 153 kHz on 31:12.2014!

Here is a German article about this decision: http://www.radiomuseum.org/forum/dlf_stellt_langwelle_ein.html

This makes me a bit sad on one side since i like the good old AM radio stuff. But on the other side, i know that i'm getting QRM from that transmitter which runs 500kW on a 350m high vertical antenna in 40 km distance. Probably there is a significant noise spectrum beeing radiated which i can see in that short distance. I can see it just a second before 20 o clock in the evening, when they switch from 500 kW to 250 kW. For 1...2 seconds, the AM carrier is off air, which lowers the noise background significantly. So maybe LF reception will be much better next year, i hope.

So maybe it is worth for some to listen for the last minutes of DLF LF transmissions on 31.12. this year :-(

73, Stefan/DK7FC
