Hi Chris and Roger - your signal disappeared with me too Chris when
you reduced power. Until then it was about 5dB above the noise with
a bin size of 715uHz. I was monitoring since you started
transmitting and I would send you a screen shot but just now I
accidentally cleared the screen!
I thought it was interesting that Mike G3XDV also reported gaps in
your signal yesterday - although at 3 hours spacing they were more
regular than they were with me.
Would be interested in trying a QRP test when the noise is lower see
if I can receive your signals - also with you Roger if you are
thinking of having a go at transmitting on your loop.

The evening (TV and lights interference) is now rising
Chris, so I think there is little chance in trying with QRP
tonight. Attached is the latest screen grab showing the signal
disappearing here at the point you dropped the PA current.
Thanks again for the test.

Thanks for trying this QRP level too
Chris. Nothing seen in 424uHz BW after that time here,
although Eddie is still getting you OK.
If you are remaining on for a few more hours (please) I will
try with a narrower setting.

Hi Chris
That's great, did you reduce power, you are still a
good signal here, keep your eye on my grabs, I am
going off watch for a while.
QRP rules OK.

Thanks
for the ongoing reports Roger.
It's odd that despite the same
settings and aerial current here my
reports seem to vary quite widely from
day to day.
I'm wondering what the other variables
are . . .
I'm preparing a spread sheet of my VLF
reports and will send you a copy when
it's done.
There's no problem with my reducing
power and at 15.30Z (16.30 UK clock)
I'll reduce the PA current to 1/10th
its present setting.

Judging by your signal level, you
might just be detectable here with
10-20dB less, especially if I
wound the RX bandwidth down a bit
more. We should try this sometime.
It would be impressive to detect
you with real QRP at your end.

Your good signal continues.
Using Spectrum Lab at 424uHz
bandwidth certainly does the
trick. BTW I also looked for
you with Spectran in QRSS30,
but not a sign with this.
Antenna here is still the 80m
wire loop in the garden. I
hope to have an outside
E-field probe set-up for next
weekend and we can compare
results although looking for
DK7FC will be a priority.
