[Titanaircraft] Radio static from Rudder Pedal movement.

This is odd and annoying...
It appears that i get a ton of static in my ICOM A22 when the rudder pedals are moved. More specifically, it appears that the Brake cables and rudder cables intermittently "break" ground during their travel and cause the static through the radio in the headset(no engine running). If I clip a 1' test lead on the rudder cable with the other end unconnected under the seat (acts like an antenna) and then run another test lead over another part of the cable, it causes the radio to crackle.
Has anyone had any problems with this or know how to fix it? The radio is unaffected if I use the "rubber duckie" antenna placed right on the radio but if I use the AC antenna on the belly, that's when the "static" is picked up.
