[Elecraft] K3/KPA500/KAT500 revs 4.83/1.38/1.58

[Carl Clawson]

All working smoothly except:

On a couple occasions, after manually initiating a tune, the tune completed
satisfactorily and then the KPA500 indicated a fault right at the end of
the tune cycle. Pretty sure it was a soft fault but I habitually hit the
button to clear it ... will observe more carefully if it happens again.
