Connecting 6400M to my SPE 1.3K-FA

Good Evening,

I have just connected my 6400M to my SPE 1.3K-FA. I purchased one of Dan's cables. I have instructions from Dan on setting the power. But what about setting the CAT so my amplifier can communicate with the Flexradio. Right now the CAT is Kenwood. Any help would be very much appreciated.

  • I pushed the Set button and went to CAT and it is now set to Flexradio. It is asking me for a baud rate. Currently the sSelection is 9600. But not sure it that is right or not.


  • Well, when I go to change the band, the band is changing on the SPE. So 9600 Baud must be OK.

  • Ok guys, I am trying to follow Dan's suggestions. But when I use my paddle I see 30 watts. But evidently it is not communicating with the amplifier, because I only get 30 watts output. What am I doing wrong?

  • I think I got it guys. I hit the menu and then TX band settings. I checked the RCA TX1 and my input is 15 watts and I am getting about 1175 watts output.
