With all due respect, that is not the question I asked. You did state, in another post, that DJI was aware that there was a range issue problem with the P3 Standard. Not a video range issue, but an R/C range issue. You stated that the engineers were working on a fix.
The short range issue on my P3S began with the September firmware update. So did most everyone else who has this problem. Before September the P3 flew to at least the advertised range. After the September firmware update, the P3 Standard will fly about as far as you can throw a paper airplane.
This is not an environment related issue. I am flying the same place I was, on 150 acre property with no neighbor for over a mile. There are no airports anywhere near me. There are no RF sources anywhere near me. I know how to position the antenna.
My P3 Standard is no longer under warranty. It has not been crashed. It worked fine before the firmware update. Since that time, I have done modifications to the R/C to increase the range. Even with a 5 watt 5.8 ghz amplifier I can still barely achieve 2000 feet line of sight. With 5 watts. The problem is in the P3 Standard. Not the R/C. Not the atmosphere. Not the stupid users. Not gremlins. ( Well, maybe some ARE stupid users, but I like to think I am not one of them in this matter at least ).
I have extensive experience with R/F ( radio frequency ) I was trained to work on R/F by the U.S. Military in 1981. I have been working with R/F ever since. Please accept that I know what I am talking about. There is a problem with the P3 Standard. I really think it is in the firmware, as the hardware did not change physically in September. Only the firmware did. Logic is clear here. It is a firmware problem.
For your additional information, HealthyDrones.com flight log shows a 100% signal strength being received by the Phantom 3 Standard that I own all the way out to 2000 feet. Even when it says Signal Lost. It does register the alert and logs the RTH event, but still shows 100%. I still have the fpv video feed, though it is beginning to fade intermittently at that range. When the quad is either moving at any range or hovering at any range, if I turn the quad in any direction, it will get no signal. It may or may not go rth at that time. If it goes rth, it may stay that way until it is very close, or it may respond to me turning off the rth mode right where it is when it spins back around to face home. There are 2 antenna for receiving the 5.8 ghz r/c control signal on the P3 Standard. Do they both receive and transmit or does 1 receive and 1 transmit. I don't know. I have not tested this. But the fact that turning the drone causes the signal to drop out should be a clue.
I know that compared to the number of aircraft that DJI has sold, this problem is probably only a small fraction of them affected. And so only a relatively few, by comparison, number of users are affected. So, if the problem is not widespread enough to register with DJI as something that needs attention, then ok. At least tell us that so we will be able to decide what to do.
Stop referring us to videos about proper antenna practices and telling us it is the environment, please.
Again, respectfully, is DJI aware of, and do they acknowledge, and are they working on a fix, for this problem?
Thank you in advance for any information you may be able to provide.
Respectfully,
Kneepuck
