[CW] "New" Keyer Feature Ever Needed?

[Richard Slone]

Hi All,
  I am keyer shopping and just saw a feature that seems to make sense, but I
wonder if it is ever really needed.  The new Island Keyer II kit by Jackson
Harbor has a debounce setting for use in straight key modes.  It compensates
for mechanical key bounce by using a default of 25 ms for the minimum
allowable time between make/break transitions of the key.   (The debounce
value is selectable from 1 to 99 ms.)  In other words, if you close the key
and it bounces a little before staying closed, the keyer just outputs a
single closure to the transmitter.
  Has anyone ever found a need for this feature?  It doesn't seem to be a
setting for the LogiKit CMOS4 which appears to be the most popular full
featured keyer kit on the market.  If this feature was particularly useful,
it would seem that other keyers would have incorporated it by now.  Any
thoughts?
  Thanks & 73,
  Richard, KG4VOX
