Horsepucky. If RF is getting into the K3, the radio has a design flaw. And it 
does -- improperly terminated shields, also known as "the pin 1 problem," which 
is a well known and well documented cause of RFI. The ONLY proper connection of 
a cable shield is ZERO LENGTH to the CHASSIS, and NOT through an RF choke!
