Hello Jim, VLF,

Jim, actually it is quite easy and logic that multiple instances can be=20
opened that way. But it took me a long time as well to find that trick,=20
actually as long as DF6NM told me about it :-)
There are several things to learn and the program can be quite complex=20
but all in all it is very close to perfect (it can't be perfect without=20
beeing complex, and complex is relative) and, on VLF, there is no (!)=20
alternative. I'm still running a quite old version here but recently i=20
had to use the latest version and actually found some advantages over=20
the old one. So it even became better :-) Once again many thanks to Wolf=20
/ DL4YHF that way!

Somehow a pity, i would like to be on air now but it's rainy, a bit. But=20
i learned that 30 kV rms is not so much for such a big coil and maybe i=20
should give it a try with some plastic foil coverage.

What about, the xmas days? Is there someone watching, maybe arround the=20
26th and 27th? I would like to run a longer experiment, maybe 3 days=20
permanent operation, testing various modes, like OPDS32. Paul Nicholson=20
told me he will write a tool to decode OPDS in his linux system and i=20
belive he will decode it!

The QRN is really low on 33km these days, amazing!

73 all
