We recommend ferrite split beads to fix this problem. Get 1/2" hole split
beads and put one or more over the bundle of cables coming into the main
amplifier. These cables pick up RF and bring it to the amplifier. The
ferrite will, hopefully, keep it out. If the cable is over 1/2" split the
wire into two or more bundles, each 1/2" or less and put a bead over each.
