With YAESU FT991A radio. For the first J1 [B] there are two possibilities AB bridged and BC this would be the option. For the second J2 [A] there is only one possibility, the only option is AB.

In side your radio settings , You need to turn off the tuner in the radio , So your only using the MFJ - tuner .

My understanding is that the MFJ interface box " Jumpers" ship default for a Kenwood Radio. This is why you must move the Jumpers for a Yaesu Radio. I'm sure by now you realize that you are doing this wrong. For the tuner to correctly work you must use all the connections !

Someone wrote on QRZ he set both jumpers to center to get his 991a to work with it

Some MFJ Antenna Tuners have jumpers that you can change over to use with lots of other radios , I Dont know if the MFJ 994b has them or not .

One more test, just plug tuner into 12v power source not using the the 5124y, they you have it hooked up, it’s only getting power from it
