    What is your Question/Problem? I am using an old Henry 2K2 with my 6400. Only tx1 relay output is needed to  control the linear amp keying,  works great here.

    I guess you want to use a RF Vox in the amp, this should work. It will be no difference for the TRX.
    I used a RF Vox in a RM Italy HF150 with another transceiver, it never worked satisfactorily due to the poor function of the amp. I sold the amp for this reason. Maybe your amp is better.
