[Elecraft] Mechanical bug contact bounce

[WA6L]

Interesting stuff, Briyce!  I have been using my Blue Racer on the K3 and
have heard the occasional erratic dot.  I thought it might be dirty contacts
(it's an old bug).

What were you hearing that made you come up with the fix?  The odd dot that
I hear is not repeatable and not regular.

Aloha and 73,

John, WA6L  (ex AH6CL)
