The MFJ-5114Y3 interface provides control signals between a Yaesu radio and the MFJ automatic

tuner. Supported Yaesu radios are FT-1000MP, FT-1000MP MKV, FT-1000MP MKV Field, FT-

2000, FT

DX-9000, and any Yaesu radio compatible with the Yaesu FH-1 or FH-2 Remote Control.

This cable plugs into the REMOTE jack on the rear panel of the Yaesu radios, and keys the Yaesu

radios in the CW tune mode whenever the MFJ-925’s [TUNE] button is pushed. MFJ recommends

that the Yaesu CW tune setting be set to 10 watts (Yaesu MP menu selection 4-3) during the tune

process when an amplifier is not used. For best accuracy when an amplifier is used, MFJ

recommends that the Yaesu CW tune setting be set to 50 watts for 100-watt transceivers and 75 watts

for 200-watt MKV transceivers during the tune process. If a FH-1 or FH-2 keypad is also used, both

the FH-1/FH-2 and the radio control cable may be plugged in parallel using a 3.5-mm headphone

splitter (mono or stereo is fine). Refer to “Yaesu Radio Interface/MFJ-5114Y3” on pages 28 to 30 for

connections and operation.

While the MFJ-5114Y3 works with the FT-2000, the FT-2000 also has a TX REQ input that can be

used. If you prefer to use the TX REQ input, the MFJ-5114Y4 interface provides control signals

between the Yaesu FT-2000 and FT-2000D radios and the MFJ automatic tuner. This cable plugs

into the TX REQ RCA jack on the rear panel of these Yaesu radios, and keys the Yaesu radios in the

CW tune mode whenever the MFJ-925’s [TUNE] button is pushed. MFJ recommends that the Yaesu

tune power setting be set to 20 watts (Yaesu menu 145 tGEn TUN PWR) during the tune process.

Refer to “Yaesu Radio Interface/MFJ-5114Y4” on page 30 for connections and operation.
