Hey Wolf,
Very nice!!! Congrats to your practical experiment!!
Are you still transmitting? Sorry, i did some adjustments on grabber2
(yesterday i changed something that increased the signal but decreased
the SNR. Today i re-built it). Thus i have not received everything. But
now i am RXing again!
If you can transmit even longer, please go on until the QRN goes down!
This process has already started. If you can transmit 100 minutes on
8970.00 Hz and after that 100 minutes on 8969,995 Hz, you could "write"
a "N" on my DFCW-6000 window! This would be a distance of about 70 km!?
Please, what is your exact QTH?
Here you can check if you are received in Heidelberg:

If you will be received, then in the DFCW-6000 window. For the "faster"
windows you may need a even stronger signal. But who knows... ;-)
Wish you good DX! :-)

Hi Marco !
Great ! You
are the first station to receive my signal. There is lots
left to be desired with the antenna. But I stay on it. I have rcvd mail
from Markus
and he will send some suggestions and calculations. Will improve the
diameter
and height in the next days. I wonder whether You deciphered the CW ID
???

de wolf
BTW
Stephan might coin an
idea on how to ID on 9kc ? he at least is the grandmaster of “DS-band “
