Hi Wolf,
That's the QTH of DF0WD, right? :-)
Well, i am in JO41GE58CG and
we will be in a distance of 103 km,

To far i think. I am here in a group of 9 persons and don't have my own
car here. But we should consider about a common LF fieldday in DL.
Seems your Sportplatz close to the shack is large enough for camping :-)
73, Stefan

Hello
Stefan,
Just for curiosity : Where in JO41 are you at the moment ? I'm very
close to JO41's "northern border" :o)
73 and have a happy holiday,
Wolf DL4YHF in JO42FD, later for BBQ in JO42FC19hu ...

Hello group,
Since yesterday in the afternoon, i'm running a CW beacon again at
137.0 kHz. Speed is about 25 BPM i guess.
It was intended to generate a test signal for my antenna tests here in
the holiday camp in JO41.
After seeing two interesting spots in the DX cluster (
http://www.dxsummit.fi/CustomFilter.aspx?customCount=50&customRange=137
) i decided to run it some days longer, knowing that many LF listeners
can cross the way (=spectrum) and note that there is something going on
in the LF amateur band.
This time i got a mail from Horst/DL2SAV near Stuttgart (JN48 i think).
He gave me a very interesting report. He is using no amateur radio to
receive LF but an old tube radio from the 60's (Schaub-Lorenz) and a
homemade tube Audion. He tells that DCF39 seems to work as the BFO, so
he can hear me in normal AM mode, like a NDB. Today he sent me 3
recordings which sound very fascinating for me. If you want to listen,
here the link:

http://dl.dropbox.com/u/19882028/LF/DK7FC_137kHz_30_Apr_112_mit_Audiion.mp3
What i don't understand: If DCF39 is the BFO and i am transmitting at
137.0, then the CW sidetone should be 1830 Hz (LSB, 138.83-137.0)? But
the tone from the Audion sounds rather like 800 Hz for me. Maybe
someone has an explanation.
BTW the beacon is stilll on the air...
73, Stefan/DK7FC
