[Elecraft] K3 bugs

[Don Wilhelm]

Dave,

Maybe I overlooked it in your initial post, but I did not realize you 
had no microphone connected.
Given those additional facts, I also believe there is some kind of bug 
causing it.  It is good that you noticed it.  I don't think the majority 
of K3 users use it for AM mode (even though it does a good job there) 
and may not have noticed.

73,
