Interesting. I didn't know about that. I suppose we need to develop
our own tools from within the LF community as we are too small to
attract attention from without.
I'm trying Windows 7 compatibility mode with WSPR-X. It has been
running about 10 hours so far and decoding K3RWR every time.
The rain has stopped so today I can look at my antenna coil and
maybe start transmitting again if the coil is OK. I will start on
WSPR-2 again but might switch to WSPR-15.

LF,
Before WSPR-15 came up in 2011, Markus/DF6NM developed a tool which
can generate and decode WSPR-15 and other WSPR modes. We used WSPR-8
(4 times slower, +6 dB) and even WSPR-30 (16x slower, +12 dB). The
program collects the data from SpectrumLab and replays it faster
afterwards, and leads the output to a normal WSPR decoder. So this
fast replayed data can be fed into the new WSJT-X program running in
WSPR-2 mode.
I remember positive tests with Jay/W1VD
If someone is interested, i could look into the details again. I
guess the program is still available. Maybe Markus want's to comment.

Rob,
I believe that WSPR15 is more viable on 136 at low powers (up to
1W ERP) on long QRB (compared with WSPR2) :)
It's like comparing OP8 (~WSPR2) and OP32 (~WSPR32).
But OP8 died a few years ago on 136

Two T/A spots from Geoff, G0LUJ, last evening on 2200M at
-35dB and -37dB show WSPR-15 to be a viable mode on 136 KHz.
I will continue nightly WSPR-15 transmissions for the next
week or so.
Does anyone have an early release of WSJT-X with the slow JT9
modes included? I believe that WSJT-X V. 0.95, r3243 released
about 04/2013 may be one release that includes the slow JT9 modes.
