Flex 6400 and Yaesu FL 7000 Amplifier

Has anyone used the flex 6400 or comparable radio with a Yaesu FL 7000 amplifier? I am desperately seeking a way to inter work the two. I know reading old posts on the old community that people do it but but I am unable to track anyone down. I really need to know how you are interfacing the radio to the amp. I used to run a 991a and had the band data cable made but another gentleman states he cannot make them. Please help!

    Up until a week ago I was running an FL-7000 with my Fkex 6600M. I was running it with out band data cable, but using the manual band data switches, you have to be careful but it works quite well. I set up power settings in the "TX Band Settings" window, selecting the RCA TX box for the apparat antenna out put and the WHALC box for the frequencies you are using the amp on.

    Steve from FlexRadio Systems has a very good YouTube video on using the Flex Signature series with non Flex amps.
    Link to Steve's video.

    I hope this helps.
