Overlapping emails with Stefan ;-) Ok, we'll both
be on 136164 then. If all goes well I'll start at 13:30 UT, repeating on
odd half hours. 73, Markus

Hi Terry,
the setup for wspr-32_rx is identical to -8, and
the same fc edits would have to be made. Yes you can split accelerated slow
WSPR from incoming normal WSPR. Using audio routing options a (two soundcards
and analog cable) or c (VAC) will intrinsically do that. With option b (analog
loopback through mixer) it depends on the choice of frequencies. I have now been
using fc = 3000 Hz from SndOutpt to WSPR, which is well out of the passband of
the SSB RX, so WSPR sees only the converted audio.
If you like I will start a WSPR-32
transmission this afternoon, using odd half hours and 136160 Hz RF (ie. 4 Hz
below Stefan's current WSPR-8). As my antenna can only operate in fair weather
I'm not sure how long I will be able to transmit
tonight.
Best 73,
Markus (DF6NM)

-32
Hi
Markus
Thanks
for the opportunity to participate in the experiment! I finally managed to get
it working with spots sent to WSPRnet with your correct frequency.
Unfortunately, I see I am also decoding “normal” WSPR because both audio streams
are seen by WSPR. Is it possible to separate?
As
you have distributed the WSPR32 file I would like to try. Other than running the
bat is there any difference in the set-up?

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,
