Dear VLF,
Unfortunately i have to delay my 11th experiment due to bad wind
situations here. Next week i'll run a 1/2 marathon, so maybe in 2 weeks.
BUT: I found that we have 2 generators here at the institute and i can
get both ;-) The small one has 1 kVA and the big one has 4.5 kVA. The
small one is very light weight (about 14 kg) so i will start with that
one in my next experiment. This means about 3 dB more power which
finally allows exceeding 100 mW ERP on 8970 Hz :-)

Dear LF/VLF group,
Back in Germany i want to announce my next VLF kite experiment, as
soon as possible. If the wind will be suitable next weekend, i will go
out again. Wind conds looks promising so far but changes cannot be
excluded until friday. So i'll keep an eye on it...
I've made a new tap on my coil. It is for transmitting on 6470 Hz when
using the 300m antenna (before it was just possible if the 200m wire
was used). I expect a signal improvement of about 4 dB from that. So
my focus will be on 8970 and 6470. Maybe i can reach 4X1RF and TF3HZ
on the 46km band :-) This is one of my goals :-)
Furthermore i will try to borrow the 4 kVA generator. This would allow
an antenna current of nearly 3A and a ERP of 500mW. Compensating QRN
by QRO!
