Having terminal blocks at strategic locations can also help to break rf paths. More by accident

We have the same controllers. Don't experience any rf issues with them. We have ssb
, han, multuple vhfs, etc.
If you don't have the interference, I'd wager you also have very good grounding throughout your systems. I talk about airplanes a lot in my few piddly answers, and that's because boats and planes have a lot of things in common. Radio Frequency Interference, or Electro-Magnetic Interference being one of those similarities. I earned a master's degree in Electrical
Engineering (electronics) many years ago and applied it to Air Force planes. One of the first things we learned was that all the (many) systems on those planes suffered EMI unless all the systems were thoroughly grounded. The grounds had to be checked for corrosion
build-up as time went on. The corrosion
acts as an insulator and you begin to pick up the EMI until the grounds are cleaned and reset in whichever unit was either transmitting or receiving the EMI. ALL of the coax going from any unit to an antenna MUST have the shielded portion of that cable WELL grounded, preferably to your engine
for a solid ground reference point that actually then becomes a true earth ground. Electrical
devices you would not expect to broadcast noise should also have their cases grounded. The metal case doesn't stop RFI. But if that metal case is grounded, the RF is channeled harmlessly to ground. Such is our modern world of toys.
