Sam, I run the KX3 line: KX3 to a KXPA100 to an Ameritron ALS-600 to the KAT500. Little lines all over the place, and hi-power LMR-type coax out of the linear. Cardinal rule, I am told, is to avoid those high power RF coax cables as much as possible in proximity. For instance, never drape a control cable or a display cable across the coax. You’ve probably tried all of this, but my two cents.
