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-939’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).
