[Elecraft] K3s Odd sound vibrations Edit - Hypothesis, Steps, Conclusion, and Request.

[Don Wilhelm]

Jerry,

While that tape works, there is a downside to it.  The K3/K3S uses the 
enclosure to assure the best shielding.  When you add that tape, you are 
reducing the points of contact between the covers of the K3 and the 
internal shields.
The impact of the tape may be small in your particular case, but may not 
in other cases.  It is dependent on just how much RF is floating around 
in your shack when you transmit.

73,
