[Elecraft] [K3] Noise from P3

[Bill]

David,

I should not think the mains 50 cycle should matter.  It would seem to be
more of a radiation issue.  That is what makes me ask about the cabinet
prep.  I have mine sitting on the right side of K3.

Thank you, Bill, interesting.  As the problem has also been reported by John
G4ZTR I wonder whether it could be due to our 50Hz mains supply.
