Does anyone seem to have problems with transmission signal distance-with any drone? All DJI drones I have ever flown seem to top out at less than a mile before the gps turns red and looses connection. I get how DJI advertises “15km range” and in reality you get nowhere near that, but I find it confusing when I can hardly get a mile out of it…

Depends a lot on the drone.

Part of the problem is the exponential increase in 2.4Ghz interference in the urban and suburban environments. Unless one takes steps to overcome this interference, any of the pre-Inspire2 offerings find themselves in serious trouble.

All of my drones are fairly old; Inspire 1 v2, Mavic Pro and Phantom 4 Pro. The latter two can simply fly in the 5Ghz frequency band, which still has some room in that space. My Inspire 1 is a different story. I often find that I have to make a choice of the least populated channel. Back in the day, I could easily find a half dozen clean channels. Not any more. The only reason I can fly it at all is because I utilize a triad of solutions:

* Legacy firmware (newer firmware reduces transmission power)
* 32 channel hack (opens up 24 extra channels that are otherwise not available)
* Passive parabolic signal booster (which focuses signal)

Remove any one of these three solutions and the Inspire becomes all but useless.

At this point I don't do any Inspire 1 jobs that are more than 1/2 mile out. Conversely, my business partner's Matrice 300 flies miles out with the remote sitting in the bed of a truck. It's quite amazing. I believe that the M300 radio technology is the same Tx/Rx technology utilized by the Inspire 2.

I made a couple videos regarding Inspire 1 firmware;

Thanks those are great points. Unfortunately I’m having this issue with the brand new Inspire 3
