The old Notebook that did such a good job in the last VLF test seems to
have a problem now. I had to switch to the LF PC. Here it works but
maybe some phas glitches occur here :-/ We'll see. After that i intend
to install a ready to use PC that is for transmiting exclusively.
Since 2:00:00 UTC the transmission should be reasonable stable.

VLF,
Now the TX is running. No HV problems this time. I'm running 500W. The
coil current is close to 1A so the antenna current may be 850mA, 3 dB
more than in november 2011.
The frequency is 8970.0050 Hz, "locked" to GPS within SpecLab.
I'm going to transmit a loooooooooong carrier until 9 UTC or so. Then
i'll play arround a bit, depending on the results of local grabbers
and activity.
Reports apprechiated.
I thought about giving WOLF10 (or 5) a try, as an exception. DF6NM
would be the intended goal but everyone is invited to receive. If i
will try WOLF then i have to use an unlocked frequency, i.e. just
using the normal WOLF gui program. Anyway, at least no glitches on
that 10 year old PC, hopefully.

PS: Odd, still 12 °C outside at 1 AM local...
