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!

The line on the map: https://dl.dropbox.com/u/19882028/LF/WSPR-8_test.png to 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:

Markus, i would agree to move to WSPR-32 now. Same QRG. Will be interesting to see the new 
spectrograms and the possible distances! :-) Oh, i musn't forget to add a switch across the cap of 
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,
