Like you say Stefan the modes are changing daily and
there are too few operators to cover all these various modes.
I expect it will all fizzle out eventually and then
back to CW, QRSS and possible OPERA
Opera was gathering momentum when there was suddenly a
Mode change and now the few LF/MF operators are all scattered
On HF there is more consistancy as I said earlier
when it comes to data modes RTTY is the most prominent with some
PSK31
but there is more normal hand sent CW about than
anything else plus SSB.
The LF/MF bands are becomming too fragmented both by
Mode and Frequency.
Meanwhile I am back to HF dxing on CW and looking
around the lower freqs for CW acty.
Watching 472- 479 and 501 - 504 and 136- 138

Re: LF: Re: Experimental software for WSPR-8 and -32
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,
Markus
