Stefan,
ah, that explains it! I was wondering why your
fieldstrength had dropped after you went up the
band, thinking that my RX calibration had somehow gone haywire.
Hope your PA doesn't mind the reactive load! Maybe you could temporarily reduce
the coil inductance by half a percent, eg. by inducing eddy currents in a
metal sheet beneath it. Or (perhaps less lossy) insert an 80 nF series
capacitor.
Anyway it looks like Jay has picked up your "QRP" signal
already!

Thanks
Mike.
Obviously my TX power is about 6 dB lower because of a temporary
metallic construction near the antenna, which brings my variometer to the lower
end, i.e. the maximum resonance frequency below 137.610 kHz.
:-(
Thus my DFCW is not affected but WSPR-15 is QRP as you can see :-( Good
luck anyway :-)

Hi all,
I've just started my WSPR-15 transmissions for
this night but was a few seconds to late. So the first slot will be 22:30
UTC.
Will someone join to LF?
73, Stefan (operator DWS)

Dave, following your notice I
reactivated the WSPR-15 receiver, though I have little hope of
catching Robert's signal in my noisy location. But Tom 'HUH
appeared on screen so the setup still seems to work.
Jay, yes I've made a habit of looking at your LF
grabber, and noticed that you've been picking up Stefan's
transmissions quite well. The weather is now getting a bit more
quiet here with less thunder, so I hope to join in again
soon.
Thanks both for your replies!
73, Markus

I'm still here ...
Yes, I've been keeping an eye out for Stefan
when he fires up 'Deutschland World Service' and broadcasts
in time slots favorable to the west ;~)

...no mails
for a couple of days - just the usual summer hole, or has
Blacksheep gone offline?
Nice DFCW
activity from DK7FC every evening, apparently aiming for Tasmania
again. Bombastic signal, as always :-)
Wishing
everyone a nice summer,
73,
Markus (DF6NM)
