Hi Eddie, thanks very much for this feedback, and
for your very useful grabber operation.
I'm quite happy about those three detections
in the UK, by you, Chris and Paul. I hadn't expected that really, as my
antenna is rather small - a total of 42 m of wire (240 pF) above
the roof of a small house. Effective height measured at LF is a little
under 10 m, probably even less on VLF. The maximum current in
this experiment was 0.33 A, limited by corona commencing above
about 23 kV. Operating times were partly limited by not wanting to
upset the neighbours enjoying the sunshine in their gardens -even
though the coil was enclosed in a big dustbin the squeaking is still
quite audible.
As they say, with QRP all the hard work is
done on the receiver side - well done then ;-)
Best 73 from Nuernberg,

Hello Chris,
Marcus, Henny, Lubos / VLF
Great to see the overnight trace from
Marcus in 424uHz. Henny sorry nothing for sure from you, yesterdays hope in
47uHz was just the odd Mal Pixel, keep trying. Lubos your signal is not as good
as on other occasions, like Marcus I am waiting for lower noise.
Chris I
did see ZEVS quite well a few weeks ago, I haven't looked lately, last year
early Spring seemed to be the right season for the lowest end
signals.
Still watching here, thanks to all for the signals

Hi Markus,
Henny, Eddie and VLF
Markus - Attached is a screenshot of your signals
in a 6000 window until close down today. I notice that you were also visible
on Eddie's G3ZJO grabber in both 6000 and 60000 windows. Still nothing here in
a 600 window.
Henny - I've now set up a 60000 (47uHz) window which I'll
keep going so if you want to transmit again over the next day or two I'll be
ready to look out for you.
Eddie - haven't seen any sign of ZEVS at
their usual times - have they gone quiet?

Now at 14:40 I have to take off the carrier on 8970.008 for a
while. I intend to come back and continue to join Henny in a couple of hours
from now.
Best 73,
