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,

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=3D50&customRange=3D137 ) i decided to run it some days longer, knowing that many LF listeners can cross the way (=3Dspectrum) 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_30Apr12_amTag_mit_Audion.mp3

http://dl.dropbox.com/u/19= 882028/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
