[Elecraft] JT65 requirements, and a possible external reference-locking option for the KX3

[Lance Collister, W7GJ]

Well, I actually had my eye on the 2m module, too ;-)  But of course, the stability 
may be more of a problem there unless there can be some user adjusted correction.

Before I ask for anything on a wish list, I sure want to give this little unit a real 
test.   Hopefully soon I can report on how it performs at the heart of a portable 6m 
EME station.   Wired up the ACC2 to amp PTT cable this afternoon ;-)
Getting ready for the arrival!  VY 73, Lance
