[Elecraft] Trouble with Auto-Spot (K3)

[Phil Hystad]

Mike,

I have version 4.60 firmware and I also use Auto Spot all the time.  But,
when I discovered this problem, after some experimenting around like with
THR and some other things, I finally tried the VFO fine tuning, before it was
on course tuning.  By fine tuning I mean TWO digits to the right of the
decimal point and course tuning is ONE digit to the right of the decimal 
point.  I hardly ever use the finest tuning of 3 digits to the right.

By the way, my THR is also 2 but I experimented with a variety of levels
when I had this problem.  I would test it again right now but I need to
get my breakfast and then head off to work.

73, phil, K7PEH
