Hello Uwe,

 

at these power level and with summer QRN you might have more luck using QRSS.

If it is helpfull I can set up a grabber in JO20IX.

Hi all,

last two nights on the air:
oz7foc, dj2lf, dk6ni, dl3zid. all 599 in jo43sv.

the rx antenna here is a mag loop 6.25 sq m tuned to 475kHz.

the above stns called CQ but didnt hear my stn.

so the ears here are OK but the output pwr of 1W seems insufficient.

If someone is interested i may convert the circuit from my mind into a schematic as a png file.

 

Always interested ;-)
