Has anyone tried one of those power line clamp on ferrite cores? Might keep the RF out of the wall wart or vice versa.
I know it saved me a lot of grief with our City AM TIS operation. We had serious RFI where the RF was getting into one of our departments FAX lines. The transmitter is located on the 4th floor, the FAX on the first floor.
The RF was coming down the phone line from the 4th floor and into the FAX line. I bought a square, snap on core at Radio Shack. I wound several turns of the FAX phone wire on the core and the problem was gone.
