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!
 
73, Markus

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 :-)
73, Stefan

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)
