ARM power messages

Hi,

 

I am seeing a bunch of these messages in the logs. Is this normal to have or does it indicate any issue with the power setup?

Re: ARM power messages

Your ARM min transmit power and your ARM Max transmit power should different by only 6. If you want the power to stop changing, make your Min and Max transmit power the same.
