Thank you Paul.

BTW, my special permission for a 300m kite vertical becomes more 
probably in the last time. Maybe i will get it in the summer, what is 
not optimal. But in that time i can make several tests and become 
experience with such high antennas. This will be useful for the 
autumn/winther time later. First i will try to make tests with a 200m 
vertical. Here a first test could be, to let the coil as it is and just 
increase the wire length. This means, i have 2x C and thus 0,7x f, so i 
can transmit on 6,3 kHz. Extreme dreaming! ;-)
What about transmissions on 6,3 kHz, the 47km band? What about the noise 
there? Would reception be possible in your distance? What about 
propagation and ionospheric modes? Other, more preferable frequencies?

For the weekend, the wx forecast is not very promising but i hope things 
will change...

Best 73, Stefan/DK7FC
