2.4 GHz Max Power output by FCC

[SMYK]

Jim

What is a maximum power output for 2.4GHz control devices by FCC ruling ?

100 mW ?
1 W (1000mW)?

Your modules got power settings to go with local regulations

I am asking because there is a bunch of new systems running LoRa or other words ELRS with power up to 1W
Is that different then STD DMSS system to go with elevated output?
Does HAM license covers the 2.4GHz band?
I am little confused because these ExpressLRS modules do not have FCC stickers

Thanks
Mike
