Stephan,
WOLF is 10 b/s bpsk, and should be run through a linear PA to limit the
bandwidth. Even at that, it does not have PSK31's carefully-shaped
envelope, and thus consumes about 40 Hz BW.

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...

Markus,
Then I'll start on that frequency at 22:00 UT, unless CFH returns.
Same as last night, WOLF(10) until 0600 UT.
I "sniffed" a little audio from the output of the TS-850 (tuned to
135600 USB) without stopping my LF grabber, and as expected, easy copy.
Nothing so far beats Wolf - and if something ever does, it won't be by
much: Wolf is very close to the theoretical performance limit.
