Looking at DJI's specs on the P3,the transmitter operates from 2.400GHz to 2.483GHz. This is the same freq band licensed for wifi. It's also this band that contains channels labeled as 1 to 14.
I don't have much experience with this so I did some quick looking. From what I see, 2.4GHz contains channels 1 to 11/14. How is it that DJI uses 13 to 20?
Gezz, the prank call buz went south so we moved to prank posting? Post and poster would have more credibility with a better use of language. Moving on.
