There is a way...

If you can arrange an osci= llator so that it can be pulled onto the
four WSPR tone frequencies (se= parated by 1.46Hz ) by two logic lines.
This could be as simple as two= resistors, one twice the value of the
other, giving a 2-bit D/A conver= ter, controlling a varicap on the
oscillator.

Then a PIC keyer= can generate the logic level drive.
See    www.g4jnt.com/WSP= RBCNS.ZIP   for details of generating teh WSPR
message= and the PIC code

The design in there uses a GPS receiver to get ac= curate timing, but
with some trivial PIC code changes it could be made= to work in a
standalone manually trigerred mode.

Perhaps there'= s a demand here...
