No PPM Signal sent from FC to Reciever

Hello guys,
I am new to Mission planner and have been working on a company project of making a FPV drone with autonomous mission capabilities. I have most of everything setup but am stuck on a couple things that hopefully tie into my autopilot (pix32 v6) not outputting a ppm signal to my receiver (RFD 900x). I discovered this issue when trying to do a radio calibration in MP when I received the error (bad channel 1 input. canceling). Found a post on Ardupilot basically saying to check my signal. I did test from FC to an external signal tester. No dice. Would appreciate guidance.

Here is a parameters list if it helps -
