With great power comes great responsibility.
The DJI Drones use the AX chipset all in one RF solution for the Ocusync system. I don’t believe they are rated to 2Watt RF output, probably half that. That’s one of the reasons I went with the regular FCC mod on my DJI FPV drone rather than using the free B3YOND patch that provided 1.4Watts.
When you drive a RF device beyond its linear operating specification bad things can happen, such as unwanted thermal issues. Then there are those you won’t be aware of, such as increased phase noise and high spurious and harmonic content.
I’m not saying that as soon as you switch your drone on you’ll bring about Armagedon, but it’s worth knowing the risks that using such powers on the 2.4GHz and 5GHz bands can create.
