Hi Markus,

The oscillator is still undisciplined -- much like your's truly.
The carrier is still on with 1/3 A RF. I was considering getting
a gps module until Stefan reported on his odyssey! In the mean time
it seems like a good idea to use NAA as a reference for Spectrum Lab.
With the RX antenna connected to the pc soundcard and the sample rate
set to 96000, VLF_stations.usr gives a sharp 50 dB cutoff at 8 kHz
and not a trace of NAA. Evidently more fiddling is required.

High voltage managment has had gratifying results. The tuning coil
is starting to look elegant with its 3 pies and a solenoid. Distributing
the kilovolts over more coils seems to have cured the sparking and
ozone spewing.

Thanks for the note, Markus.

Tom and Bernd are preparing to install a second earth antenna to the northwest soon, supporting a cardioid in your direction.
