Jumper JP2, located behind the front panel circuit board, selects the radio to be connected to the
Radio Interface connector. Set this jumper to the “I” position to interface with radios that are
compatible with the Alinco EDX-2 tuner, Icom AH-3 and AH-4 tuners. Set the jumper to the “K”
position to interface with radios that are compatible with Kenwood AT-300 tuner. Set the jumper to
the “Y” position to interface with Yaesu FT-100; “1” position to interface with Yaesu FT-817, FT-
857 or FT-897; and “2” position to interface with Yaesu FT-847. If no cable is connected to the
Radio Interface connector, set the jumper to the “0” position to disable the interface. Default is “0”.
