[Elecraft] K3S Proper Grounding

[Bob McGraw - K4TAX]

Yes the Buckmaster does use a current transformer however that method 
does not provide much if any common mode rejection.  As to why one radio 
does it and one radio does not, something is different in your system.

Make sure each piece of equipment is tied {bonded} to a common point for 
your station.  In my case, I use the power supply ground terminal as the 
common point.  Also, since you have swapped radios around, highly 
suspicious would be coax jumper cable being defective or a PL-259 not 
being tight.  I always snug my PL-259's with a pair of 4" Channel Lock 
pliers.   With some brands and manufacture of connectors, finger tight 
is not good enough.
