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

Alinco Radio Interface

The MFJ-5114A radio interface allows users of EDX-2 compatible Alinco transceivers to connect to the

MFJ-925 IntelliTuner™ Automatic Antenna Tuner. With this interface, control signals are connected

between the radio and the tuner. The operator can then control the tuner with a single push of the

[TUNE] button on the front panel of the radio. Supported Alinco radios are DX-70, DX-77, DX-701,

DX-801, and any Alinco radio that supports the Alinco EDX-2 tuner.

Connections

1. Turn the tuner off. Set jumper JP2 to the “I” position.

2. Insert the 8-pin modular plug into the tuner’s RADIO INTERFACE jack.

3. Important

: Make sure the DC power to the radio has been turned off. The radio does not fuse the

DC power to the tuner, and damage to the radio can occur if the interface’s power connection

comes in contact with ground.

4. Connect the 5-pin molex connector to the mating 5-pin molex connector, marked as ACC, on the

back of the Alinco radio.

5. Push the [POWER] button on the tuner to the in position and then power on the radio.

Operation

The operation of the MFJ-5114A radio interface is similar to the operation of the EDX-2 described in the

Alinco operating manual.

1. Push the [TUNE] button on the radio to initiate automatic tuning process; for DX-70 press

[FUNC] then [TUNE]. The radio will automatically switch to CW mode, transmit a 10-watt

carrier, and start the tuning process. “TUNE” appears in the radio’s LCD while tuning; do not

change the frequency or mode while tuning. When the tuning process is completed, the radio will

stop transmitting, return to its previous mode and power setting; “TUNE” disappears.

Note the [TUNE] button on the tuner

will also key the Alinco radio interface.
