OK Rik
 
May be your way is simpler. I was thinking along the lines of an exis= ting SSB rig in most but not all shacks existing free software - 3 x= 2n2222 devices a mixer chip an xtal and may be a fet pa like what G3XBM= has proposed.
 
Phase shifting a carrier which in the software is done at audio in ol= d Joe whats his names software can be done at RF cariier frequency granted= .... but is it over all simpler than a transverter method described above= ?
 
Having built your 500kc/s transverter all other free to down loa= d diggi modes are then possible (Goord 'elp us) even dare I say CW .......= . oh thats not PC on this reflector forgot.....  slapped wrists.

Pete,

There is no need for linear amplificat= ion with WSPR, so things can be kept simple.
Another way to get a 500kH= z WSPR signal is to generate WSPR with the tones 14.6Hz separated at 5MHz= and then divide by 10.
As Andy states the WSPR protocol is public (and= pretty straightforward), so writing the appropriate software shouldn'd be= to hard.

73, Rik  ON7YD - OR7T

Quoting M0FMT <m0fmt@yahoo.co.uk>:

>= Probably simpler to to make up a transverter - mixer with a xtal  co= ntrolled oscillator and a few stages of linear amplification  driving= the mixer with an SSB rig. The whole thing about WSPR is the  Low po= wer aspect so no QRO linears required if you play the game.  Then use= the readily available Software that can be down loaded for  free....= no brain surgery required.
