Hi Paul,
The tuning coil is rather small and lossy. The best range is
5 km using a DK7FC E probe and Spectrum Lab with QRSS100.
I don't have a GPSDO yet, but Markus says the dual oven osc
should be stable enough.
I'd like to get a long piece of wire to make a better coil
and see if the signals are getting past the near field.
If 20 uW is ever realised, I'd be happy to send you a carrier. Thanks!

PS getting ready for another 8K18A sequence. 0000 UT.

Great. My rx is recording again with a fresh charge in
the battery.
On VLF, CW on 8.277 kHz was heard
at just over 1 km
Should I be looking for your carrier? Can you reach
20uW ERP, GPS locked? If so, try sending 2 hours of
unmodulated carrier between 00:00 and 06:00 UT.
It would be great to see some VLF activity. Very little
sign of amateur activity seen here lately.

you can scroll back four months and there's nothing. A very
quiet band indeed!
