All these channels were there to begin with right? No questions about that. If they were not productive then why did DJI choose to keep them in? Not only keep them in but have it auto configured to select the best of 32 channels! Then right around 2 months ago people's range started to dwindle.....at that time they cut back the channels by a lot for an unknown reason possibly license agreement or fees associated with more frequencies, I don't know nor does anyone at this point. But for some reason DJI only included 8 channels and 8 of the most congested channels out there! 13 to 20 light up red all the time by me and the few places I've traveled to. I do know for a 100% fact that flying on these red spiked channels gets me 1200 feet repeatedly around my spaceship. Now when I manually switch to the upper channels 30,31, 32 there is no action at all on these channels and I can easily double my distance in the same spot. Now something is responsible for that. And I will restate that our channel 13 is NOT the restricted frequency some think it is. 1-32 is an internal numerical delineation by DJI as channel 13 has a lot of action on it from wifi activity in a number of areas I've traveled to. So to sum it up, we can all continue to question how and why regarding these extra channels, but not , in my opinion, the fact that they work or not.
