[Elecraft] K3 TVI on 40 meters only

[Jim Brown]

This is an example of what I was talking about (quoted below) that I 
can't think of any mechanism whereby ANY ham rig is the CAUSE of RFI, 
and an example of several common mechanisms within those systems that 
make them susceptible. Their equipment and systems SHOULD reject or 
signals and fail to do so, thanks to failures in design, manufacturing, 
and/or installation.

In other words, it is ALWAYS their fault.
