Hi
Rick, VLF'ers
I was about to lose all hope but finally the 8k carrier from Rick has
been detected from my system! This should be the first ITA-ITA
detection.
I've tried many times without result, also because of strong local
noise, but after some test with loop and whip antennas I've recorded
this (weak, indeed...) trace.
QRB is about 385 km and a 3/4 of the route are mountains, the
spectrogram is a 47uHz on the 40 turn loop.
Thanks to Rick for his fine work, I hope to find soon a low noise place
to get better results.
Probably also some better propagation conditions helped me to receive
Rick.
Now We'll try for an EbNaut short message, who knows what will happen?

Re: VLF: Carrier on 8270.0025
Hi VLF,
I'm running another carrier test on 8270.01953125 with about 600
mA
and 14 µW ERP.
To reach this current, I need about 290W on the PA output,
currently
supplied with 62V and 5.5A.
There is a lot of power dissipated by the coil: a cooling fan is
absolutely necessary.
All the best
