[R-390] SSB R-390A?

[Les Locklear]

Airborne, that was it. Thanks Tom! I hadn't had enough coffee before 
replying and I had a senior moment.....:-)

That wasn't a "Depot" job, depots didn't do modifications except for factory 
approved field mods. All the ones I have seen (they aren't rare at all) have 
the HC-6U?  smaller x-tals, looks like somebody had a bunch of surplus 
FT-243's to use up.

Maybe he had Martyn write up that "hype" for him?
