Ok, with THIS kind of signal you can go up to 120 cpm Stefan. Well done !

But the QSB is still crazy, isn't it ?

=C2=A0

During your QRQ over, the signal peaked 579 but then dropped down just above the QRN level.

As you said, you should fix the antenna at that place. Hope it didn't catch too much attention by hikers :)

Hallo Stefan,

=C2=A0

Bitte mal etwas weniger schnell geben, dann w=C3=A4re das Signal hier bequem lesbar.

=C2=A0

So, mit =C3=BCber 80 BPM,= nur 339 mit viel QSB + QRN :o(

=C2=A0

(please a bit slower, your high-speed CW is a bit too fast at the moment. Maybe later. Tried to call you once but no response besides what may have been a "QRZ ?")

=C2=A0
