[Elecraft] K3-Tuning rate

[Don Wilhelm]

Fred,

Change VFO CTS  See the statement in the menu chart -
"VFO counts per turn (100,200. or 400).  Smaller values result in easier 
fine tuning of VFO; larger values result in faster QSY."

You have yours set for the fastest rate - 200 is the default.
Yes, that will also change the 10 Hz tuning rate.
You will likely want to change VFO FST as well to get the fine tuning 
you want, and that might also lead you to use the Coarse rate rather 
than 10 Hz for faster QSYing.

You should have some drag on the VFO knob.  IMHO, you should not be able 
to spin it for more than 3/4 turn.  With very light drag, it is more 
difficult to get it to refrain from drifting a bit when you remove your 
hand.  Also your fast VFO CTS contributes to this situation as well.

73,
