VLF,

I'm now running 350W into the system and get = about=20 0.8 A antenna
current. Strong audible partial discharges occurr on a = parallel fixed
plate capacitor, spaced by 3 cola bottles (0.33l ;-) = ). At=20 550 mH i have
25 kV rms on the antenna and coil which seems to be no = problem=20 at all.

The frequency is still a bit unstable since i took the = DDS VFO=20 which is
more comfortable to find the resonance. I will now try to = slightly=20 QRO
and then apply a fiber optic cable carrying the GPS locked = frequency=20
coming from the PC/SpecLab, hopefully without to many phase = glitches.=20
Currently i may have an offset of some 20...30 mHz and a slight = drift=20
but it is a first successfully test :-)
