[Elecraft] K3 Start Up Problem

[Peter Chamalian]

Over the past 6 months my K3 has developed a curious problem.  When I turn
it on and it goes through it's "boot" cycle, I go to key the radio the rig
does not key properly in that it drops a dit or dah.  It makes no difference
what antenna I use or if the amp is on or off or what I use to key the radio
- computer or external paddle.  After a warm up period of say 5 minutes,
all's well and the rig keys normally.  This gets to be a problem if I turn
the rig on and there is something I want to work immediately.  If I wait
then all's well.

 

I'm guessing there is either a board or component that isn't totally happy
until this warm up is complete.  Thoughts appreciated.
