The MFJ-5114K interface provides power and control between a Kenwood radio and the MFJ
automatic tuner. Supported Kenwood radios are TS-50S, TS-450S, TS-480HX, TS-570S, TS-690S,
TS-850S, TS-870S, TS-2000, and any Kenwood radio that supports the Kenwood AT-300 tuner.
Push and hold the radio’s [AT TUNE] button for one second to start the tuning process. Push the [AT
TUNE] quickly to bypass the tuner or to cancel tuning in progress.
Note: The TS-480HX will automatically reduce its TX power to 100 watts maximum (25 watts
AM) when the radio interface is used.

The MFJ-5114Y interface provides power and control between a Yaesu radio and the MFJ automatic
tuner. Supported Yaesu radios are FT-100, FT-817, FT-857, FT-897, and any Yaesu radio with
compatible CAT system. Push the [TUNE] button
on the tuner
for 0.5 to 2 seconds to start the tuning
process.
Important:
The +13.8 volts connection on the FT-817’s CAT port cannot supply 750 mA of
current needed by the MFJ-928. So remove jumper JP1 located in front of the
Radio Interface jack, and use a separate DC power supply to power the MFJ-928.
