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
