Hello Wolf, MF,
Wolf, you're using not the latest version of your software! ;-)
Many thanks to all who helped in this test. Thanks for the QSO to
DF0WD, DF6NM and DL2HRE.
My first impression is (and the QSOs confirm it) that a dipole on the
630m band is a real alternative to a vertical antenna. Also it is much
easier arranged and can be wound up on a roll which finds its place in
a backpack!
My 12V PA generated about 50W RF power during the QSOs, supplied by a
single 12V / 7 Ah lead acid battery. So the complete MF station
including the RX, antenna, Netbook, PA, CW key, tuner, antenna and
cables can find their place in a backpack!
You can imagine that the man made noise was very low. But there was
heavy QRN as the band opened. The final construction was a 280m long
dipole which was resonant at 467 kHz. It has a BW of about 20 kHz
(SWR=2 corners) and an SWR of 1.2 on the resonance frequency (R=69, X=0)
During the QSOs, the dipole was just 4m above the wet ground!
A detailed report with all measurement data, different feed point
measurements, different heights above ground and pictures will be sent
tomorrow.

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 ?
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 :)

Wolf DL4YHF / DF0WD .

Hallo Stefan,
Bitte mal etwas weniger
schnell geben, dann wäre das Signal hier bequem lesbar.
So, mit über 80 BPM, nur
339 mit viel QSB + QRN :o(
(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 ?")
73, Wolf
