[Elecraft] K3S proper grounding?

[Phil Hystad]

I had the same problem and it occurred on 40 meters regularly as well.  Low power (~80 to 100 watts) did not seem to bother the TV but it was a regular problem at power’s much over 100 watts.

My solution which seems to work flawlessly so far with max power of 600 watts is that I took a whole bunch of the clip on wrap around conductor ferrites and put it on the power cord.  They run for about half the length of the 120 vac power cord to the TV set, about two dozen ferrites.

I had the same problem with the Bose table-top radio upstairs.  Key down at >100 watts would invariably turn on the radio.  But, the Bose table-top radio uses the power cord as a default FM antenna so wrapping in ferrites required another antenna solution.  So, I created a makeshift FM antenna up on the roof and ran RG-6 cable to it where it connects with standard TV like RG6 cable connectors.  This fixed that problem too.
