I remember at Dayton about 3 years ago, seeing the introduction of an HF rig 
made by Motorola, strictly for Amateur use. I'd be willing to bet that radio 
(can't recall the exact model number off hand) would offer a design that was 
much more pure on CW, because I remember it as being Mil-Spec approved.

  Convincing the manufacturers to give us better 160m rigs is surely a good
  idea.  But what about all the otherwise great rigs already out there that
  will continue to click up the band for years to come?  How many of us are
  going to try any surgery on our highly miniaturized & fragile rig internals,
  just to reduce key clicks?

  Hams are mesmerized with all the add-on equipment available to us.  Look at
  all the audio enhancement, keyer & other equipment in use today.  It seems
  that a modified keyer, with the output rf brought through it, could clip the
  beginning and end of each CW character, applying the proper rise and decay
  rates for the chosen CW speed.  The reaction to keyer input rate would have
  to be delayed slightly, but would not be noticeable.

  While I do not have the ability to build such a circuit, I would not
  hesitate to purchase such a device, were it to become available.
  Then with an available fix for keyclicks to existing rigs, the FCC & other
  international communications agencies could begin to tighten allowable
  keyclick bandwidths, bringing new rigs into spec over a period of time.
