It's a pity that there is no slow-WSPR, e.g. needing 32 minutes or so.
If WSPR (2 minutes FSK) is about as efficient as OP8 ( i heared so),
then it should be a real alternative to the slow DX modes on LF but not
on MF!
There is a software that plays recorded audio files in a faster mode, so
that QRSS becomes audible. VE2IQ has reported to me last year about it
but i don't remember the name.
Would it be possible to make our own slow WSPR by using that software
and playing a 32 minute manipulated WSPR at 16x speed, feeding it to the
normal WSPR rx software? The slower code could be generated outside the
program. Would that be a useful test or do i miss something?

But once again Jim has the answer to this problem ..if you can
find his articles after Google trashed the uk500khz news group ,
I think Jose R predicts a 6 dB gain by changing to PSK from
the Opera on/off keying but that would prevent most of the
LH/MF usage
