Hi Stefan, Chris,

in principle yes=E2=80=A6 (R. E= riwan)

The old tools from 2012 are here 
http://df6nm.bplace= d.net/wspr/slowWSPR.zip
But they used a homemade 16-bit-utility "w= aitraster" for timing, which is no longer supported by 64-bit Win-7 and Win= 10. This can be replaced by simple DOS commands, which has so fa= r been implemented for receiving WSPR-15
https://klubnl.pl/rsgb_lf_= group-archives/html/rsgb_lf_group/2018-11/msg00318.html
but not yet for = transmitting. So a little more work will be needed.

On the= other hand, I'm asking myself why so many people still insi= st on having dividers before their PA's. It only makes life = more difficult, and undermines coherent EbNaut or Opera signal tr= ansmissions. 

Best 73,
Markus (DF6NM)

Chris, it would then be worth to try t= he normal tool first.
