[Elecraft] Does anyone...

No, not at all compatible.

I sort of thought you hadn't built anything yet, and the PIC-EL approach
could give you similar functionality for a lot less bucks.  Plus, there's
other fun stuff to do.  Actually, the QST project, I think, has a little
more message memory, too.  I seem to recall an external serial EEPROM there,
the PIC-EL only has the F84's onboard EEPROM which is pretty limited.

If you're looking for a plug-in replacement for the SX28 then the 16F84
certainly isn't it!
