First dahes from Stefan's dipole around 17:00, he
said he got about 20 watts RF input. SNR here around 18 dB in
1.46 Hz FFT in broad daylight. Apparently someone else called in CW but not yet
strong enough to read here.
Stefan will try to optimize things a bit and get on
air in a short while.

MF,
I will now start to do my tests with the MF dipole. It
may take 2 hours
until i am QRV.
I have a CW key and a PC to allow Opera4
transmissions. For CW i want to
transmit on 472.5 kHz, so if you want to
try, just see if you can catch me.
