[Elecraft] K3--Strange Issue On 40 SSB

[T. David Yarnes]

Aha!  Thanks Greg.  I was feeling like perhaps I was 
screwing up something in my setup.  Glad to hear that it's 
probably just one of those quirky problems that crops up, 
but will be addressed.  You made my day!

Dave,

This is a bug that was just recently found.  We're in the 
process of testing
updated firmware to fix this.
