Thanks Bill,

Many mails. I'm just answering your first one, pse QRX ;-)
Can the WOLF10 program configured to generate a 8970 Hz audio output?

If you want to try an audio WOLF-10 file on 8970 Hz here is a .wav file recorded at 24000 samples per second. You can run it into your Tx (using a dummy load of course :-) and see what the sidebands look like. Wonder if anyone (Andy?) can decode it? How many dB down do you have to be at 9 Khz? Get the file here (only about 27 Kb zipped): http://www.magma.ca/~ve2iq/wolfsamp.zip

Hmmmmmmmmmmmm, so what about a WOLF VLF test? Can the program easily be configured to transmit at 8970 Hz? I.e. does it generate a tone at that frequency? Please confirm that no linear mode PA is needed. Wolf 10, means 10 Hz bandwidth? Sorry for the basic questions, i could read the manual but its like reading readme files ;-)
Starting with local tests should show the limits and chances.
DD7PC who is in 77 km to my fixed location gave a WOLF report today, so maybe... And if OK2BVG can reveive my DFCW-3 from the 300m kite, it may be worth to spend some time for a WOLF.
I could ask Michael Oexner first. He is just 45 km distant...
