If you can generate the signal of your
previous tests , I don't think the range
will be that short !!
Due to the long tx pulses of OP4 Hr ,
the signal will also show on spec-lab , so
test data is not lost , if decode fails
.
The software produces the 8K audio tone
via the sound card and has the com-port on/off
keying output as well , normal sound cards
are suitable , the software inputs directly
at 8K using sound card as SDR
If you have a target date , I can post
in the Op group for monitor's
73-G.

I'll give it a try Graham. The problem may be to find monitoring
stations in a short range...

Hi all,
Hmmm, theoretically we can generate every WSPR
speed now. Markus, should we try a WSPR-256 on VLF/ 8970 Hz? :-) I still have
the big coil in the cellar and the band looks fine :-)
