Hi Stefan, all,

 

And i wrote&= nbsp;an email to PE1NNZ<= /a> and asked to a modification of the C-program to gen= erate a signal with&= nbsp;4x higher = FSK shift. Then = ;it it would be possible to use that&nb= sp;version for = OMs having a di= vide-by-4 stage in their= PA (to get a perfect 50% duty cycle and rectangular shape (after passing optocouplers= etc)). This would be a safe way to drive my QRP PA, testwise of course...

I have written such= a program for windows (actually you can set the devider ratio to any number between 1 and 100).
That way a= ny HF TRX can be used to gerate a MF (or LF) WSPR signal with a simple CMOS ot TTL divider IC.
If anyone is&nb= sp;interested just l= et me know ...
