[Elecraft] KX3

[Mike Murray]

Just received an almost unused KX3 from a friend and seem to be having a
major problem.  When first turned on, all is well and everything functions
as expected.  After a time, it acts as though the VFO is locked and won't
change freq., even if I change bands.  It is not locked because I have
tapped the RATE button just to be sure, but still won't change frequency -
the last digit just blinks.  Powering down and restarting seems to work for
a while, but it eventually starts doing the same thing.

I'm assuming it's OP error and would welcome any input as to what's going
on and how I prevent it.
