Hello,
Just purchased from UMT shop a 500mW 3DR Telemetry Kit V2 (433MHz)
All is good, updated firmware in Mission Planner on both, set personal id on both. 
However maximum power level number that is listed is 20, equating to 100mW, how can I set it to take advantage of the 500mW capability of these radios?
Thank you
Steve
