The MFJ-5124Y interface provides power and control signals between a Yaesu radio and the MFJ
automatic tuner. Supported Yaesu radios are FT-100, FT-450, FT-857, FT-897, FT-950, and any
Yaesu radio that supports the Yaesu FC-30 tuner. Push and hold the radio’s (TUN) or (TUNE) key to
start the tuning process. Refer to “Yaesu Radio Interface/MFJ-5124Y” on pages 35 to 38 for
connections and operation.
The MFJ-5124Y2 interface provides control (but not power) between a Yaesu radio and the MFJ
automatic tuner. Supported Yaesu radios are FT-847 and any Yaesu radio with a compatible CAT
system. Push the [TUNE] button on the tuner for 0.5 to 2 seconds to start the tuning process. Refer
to “Yaesu Radio Interface/MFJ-5124Y2” on page 39 for connections and operation.
The MFJ-5124Y3 interface provides control (but not power) between a Yaesu radio and the MFJ
automatic tuner. Supported Yaesu radios are FT-1000MP, FT-1000MP MKV, FT-1000MP MKV
Field, 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-993B’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-5124Y3” on pages 40 to 41 for
connections and operation.

The MFJ-5124Y4 interface provides control (but not power) between a Yaesu radio and the MFJ
automatic tuner. Supported Yaesu radios are FT-2000 series, FT
DX-5000 series, and any Yaesu radio
with compatible TX REQ jack. 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-993B’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-
