MAVLink loss

We’ve been using an RFD900 module for telemetry, and have had consistent issues with packet loss. We see a loss of around 70%, and this prevents the vehicle configuration from showing up in QGC around half the time.

I’m certain its not a physical problem, we’ve taken the RFD out of the vehicle, tried different antennas and have seen the same issues. We’ve tried adjusting telemetry baud rate higher and lower, and haven’t seen a change.

Anyone else have this issue?
