Hi LF,

Thanks for the test signals and advice.

Well i used my portable LF receiver, an active bandpass (no voltage gain but a high Z input and a 50 Ohm output) as a frontend. There is no earth on the tree so i took a 4m long wire hanging down. The antenna was a simple wire, maybe 1.5 m long hanging into branches. So it was just a first test. Then there was QRM from the tablet PC. It was possible to reduce it but it is not ideal. However i like to follow the idea of LF on the tree, at least i will do tests to see how much better the reception is relative to the city.

DCF39 had an SNR of  about 80 dB in 1 Hz.
I'm quite sure i saw the OP32 signal of G3XDV.

I'll continue to play...

73, Stefan

I'm now QRV on 137485.00 Hz in op32

GL Stefan.
