Hi Stefan,

 

for the broadcasters LF (and MF) is the past. LF / MF transmitters and their antennas are very expensive to maintain and these days the audience is small.

More and more LF / MF broadcast stations will go QRT.

But let's look at the good side: apart from less QRM it is likely that in the future there will be more space available in the LF /MF range and the ham bands can expanse or we can even get new bands.

Onderwerp: LF: DLF 153 kHz QRT

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
