Hello Gerhard, Lubos, LF,

G3XIZ seems to transmit a beacon signal in QRSS-3 just below 137.7 kHz.=20
Maybe he is further improving the system. He is very weak visible here,=20
probably having a QRP signal.
Unfortunately i cannot go much below 40 W with this PA since the driver=20
uses the same supply as the PA itself....

Conds seem to be good this morning, QRN is gone, at least now.

Good luck all with improving antennas and receivers :-) I'm going to=20
build a step down converter (320 VDC -> 0...320 VDC) to control the TX=20
power of my new PA, using a TL494...


73, Stefan/DK7FC
