RCA output from rca TX1 on 6300

I have a "new to me" 6300 running
I going through a huge learning curve, and when I got to connecting the radio up to my Alpha 8410 ( that I use with 4 other radios) RCA tx1 doesn't provide a closure on the Amp, when radio is keyed. The txband settings are set to "ON" and the output of the TX1 shows a closure on my fluke dmm, when the flex is put into TX.

I have tried different transmit timings, etc ...that didn't make any difference. I did make sure the amp DOES key when the center pin is grounded. The amp does use low V keying

Any clues?
thanks in advance 73 K2WW
