[ARC5] [Boatanchors] BC-348 Backlash Suggestions

[Michael A. Bittner]

So, in all this back and forthing about backlash, etc. how come no one has mentioned the word "hysteresis".  The delay between action on a system and the reaction of that system.  Applies to mechanical systems, such as gears trains, electrical systems, economic, thermal, chemical, and any number of things.  Mike, W6MAB

  Hi,

  I have experienced both kinds of these foilbles in tuning dial works.
  The generic backlash in geartrains that I am familiar with is the play
  between parts. The irritation from "torque windup" that drives the
  mechanism backward a little when we let go is slightly more irritating
  than just having to move the dial a little further when backing up onto
  a signal. I don't really like either one. My dadios don't do that. One
  or two used to. They're *GONE*.
