Markus, i would agree to move to WSPR-32 now. Same QRG. Will be interesting to see the new
spectrograms and the possible distances!

Assume that you and Markus will be operational in WSPR-32 during the overnight as well? If you can,
please TX running until shortly after your sunrise.

Hi Markus, Jay, Terry, Chris, LF,
Thanks for the yesterdays WSPR-8 tests!
Somehow i thought there would be a more general interest in these experiments but maybe it is to
complex? Don't know... Another effect may be that we try daily change the modes. But this is
experimenting. I hope that WSPR-32 will be a more serious alternative. From what we saw in WSPR-8,
WSPR-32 must be very promising and i'm optimistic to have a decode from Venezuela!

W1VD is very bulky :-)
There were 11 decode by W1VD:

Only 2 of them would have been in the range for WSPR-2 decodes. So the slower mode certainly helped
to cover a wider time range.
There are 3 grabbers showing the occupied bandwidth of WSPR-8 and later WSPR-32:

the watchdog timer ;-)

Thanks very much Jay, Terry and Chris for taking the effort to receive and report our experiment,
and of course to Stefan for suggesting it in the first place. I think the expected gain in
sensitivity is evident, even though there is no "miracle machine" of course. I have now ended the
WSPR-8 transmission from Nuernberg for today.
How would you like to proceed from here? Try WSPR-32 next? Perhaps a slow WSPR experiment on MF? Or
wait for Joe's 8-FSK mode JT8 which might knock off another dB?
BTW I don't use a transverter for MF, but an FE-5680A Rubidium synthesizer which can be controlled
to generate WSPR directly.
Best wishes, and have a nice Sunday,
Markus (DF6NM)
