[Elecraft] Trouble with Auto-Spot (K3)

[paul ecker]

Phil - I tried your suggestion of using VFO fine tuning and that does seem to help. I do not see the signal being driven off as I had previously. Will keep experimenting with. Thanks for the suggestion,

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

I noticed that my VFO was on course tune so I switched to fine tune and now the SPOT feature worked just fine.  It seems that the VFO must be in fine tuning mode for this to work but I don't remember this always being the case.  I can't say for sure but I think I have used SPOT with CWT on both fine and course tuning and it always worked.  Well, at least I think it was that way.  My guess is maybe something changed in the recent update.
