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.

73, Stefan

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.<br>
    <br>
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.<br>
