Icom IC-2720H (IC 2720 H IC2720H) RFI in mike

I have a easier fix to solving RFI in getting into the microphone.

Move the Toroid coil from near the transceiver to the remote head. I had a problem with RFI locking up the transmitter while operating at high power. The control head & mike were within 2 feet of the antenna mounted on the roof of the vehicle.

Moving the toroid coil solved my issue.
