----------------- Good points! Has everyone chasing he noise problems at least isolated the house mains from the rig for RF with a ferrite choke? Since the K2 uses an external power supply, I use chokes on the 13 vdc supply lead where it leaves the K2. I don't have your problem to contend with, so I can't say what difference it might make. On HF, I currently use a balanced antenna fed with open wire line through a balanced ATU, so rig grounding isn't a big concern, but on general principle I like to isolate my rigs for RF to avoid unwanted noise getting in and to avoid unwanted RF "grounds" from occurring in the house wiring.
