Crossfire Telemetry signal strength

Hello, I’m new to Pixhawk and am having issues with the telemetry on the Crossfire and was hoping someone might have some insight to offer. The best I can get is 10-15% as shown on the artificial horizon on the Flight Data screen.

Is there some additional param, like stream rates (SR1 or SR2) that need to be adjusted?

Thanks for taking a look. I can provide additional build information for context if needed. This is obviously a multirotor, it’s running a Pix2.1 with a Crossfire Diversity RX and a 2.4Ghz vtx.
