There's probably not an easy way to fix it -- it's established by how 
the radio is built, and changing would be major surgery. These are 
things that Elecraft has to fix.

What we CAN do is "put band-aids" on the problem. Several basic measures.

1) Bond chassis-to-chassis of all interconnected equipment, bond from 
that equipment to all grounds, and carefully bond all grounds together.

2) Place ferrite common mode chokes on cables plugged into connectors 
with Pin One Problems, tuning the chokes to the frequencies where 
interference is a concern. Follow guidelines in k9yc.com/RFI-Ham.pdf

3) Keep cables plugged into connectors with Pin One Problems as short as 
practical.
