No radio in Qgroundcontrol, but works fine in Mission planner

I’m working with my first ArduPilot drone and got it all working fine with Mission Planner, but wanted to try out QGroundControl. Telemetry works fine from FC, but I don’t get any signals from the radio controller..

Any suggestions what could be the problem with QGroundControl?
