I changed the subject ;-)
The settings were not bad, just the delay/echo line was enabled, which
is not necessary.
In attachment is another usr file with some more complex settings
optimised for individual noise blanking on 8270 / 11904 Hz. Maybe it
works a bit better. Just try and compare.
If everything is configured fine then you should reach the far field
easily. Maybe you can make a recording (wav file), 1 minute would be
fine. Are you using the latest SL version?
How stable is your signal? Would be interesting to see a spectrogram of
your own signal...
A VLF grabber on the historic hill, what about that? :-)

It seems the delay is a blacksheep thing. Fortunately it doesn't
Your reception of my VLF will be a big day indeed. At the moment, the
sigs appear to be constrained to the near zone. The best DX was 5.2 km
using spectrum lab but this is now only about 1 km. The signals are
quite audible with a crude RX at 1.5 km. Evidently, this OM is not
competent in SL operation. Perhaps this can be verified by looking
at the attached configuration file which was modified (bungled?) from
Wolf's 8270Hz_QRSS_4mHz.usr. The level range in the output file is -145
to -81 dB and the spectrogram shows a peak at 8277.16 Hz.
Thanks for your offer to help!
73 and congrats to you and Paul again.

Your recent emails came through now, with some delay since the 27th.
Thanks for your kind words regarding ULF. We are waiting for your
signal on VLF. A true RX challenge for me!
If you need help with special SpecLab configs, we can arrange a
Teamviewer remote access. I'm doing this daily now on various PC in
various countries :-)
