MFJ-925 Super-Compact IntelliTuner Automatic Antenna Tuner Instruction Manual

Jumper JP2

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, Yaesu FT-1000MP series,

FT-2000 series, FT

DX-9000 series, and any radios that are compatible with Yaesu FH-1 or FH-2

remote control. 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 radios that are

compatible with Yaesu FC-30 tuner. If no connection is connected to the Radio Interface connector,

set the jumper to the “0” position to disable the interface. Default is “0”.

Table 1. Jumper JP2 Setting.

Jumper JP4

Jumper JP4, located about one inch or 3 cm in front of the Radio Interface connector, inside the MFJ-

925 must be configured properly when interfacing to the various radios. Normally this jumper is

installed and is the factory default. Remove this jumper when interfacing to an Icom IC-7000.

Make sure this jumper is installed when interfacing to Kenwood radios and FC-30 compatible Yaesu

radios using the MFJ-5114K and MFJ-5114Y interface cables, respectively. For the other radios, the

position of jumper JP4 is irrelevant.

The MFJ-5114A interface cable provides control signals between an Alinco radio and the MFJ

automatic tuner. Supported Alinco radios are DX-70, DX-77, DX-701, DX-801, and any Alinco

radio that supports the Alinco EDX-2 tuner. Press the radio’s [TUNE] button to start the tuning

process; for DX-70 press [FUNC] then [TUNE]. Refer to “Alinco Radio Interface” on page 21 for

connections and operation.

Pin 1 (Ground) connects to pins 4 and 5 of Radio Interface Plug.

Pin 2 (+13.8V) connects to pins 2 and 3 of Radio Interface Plug.

Pin 3 (Key) connects to pin 6 of Radio Interface Plug.

Pin 4 is not connected.

Pin 5 (Start) connects to pin 8 of Radio Interface Plug.
