[GreenKeys] Fake TTY/crypto equipment

[John, W9DDD]

"just lie down until the  feeling goes away".....

If only I had done that a bout 3 years ago I'd have a lot less GA and BR

You could hide a Raspberry Pi inside and have it actually perform some 
pseudo crypto like trick. (5 number groups?) Finally a use for the 
Synchronous Pulse Transmission feature.
