AHHH  I have the P3A.........oh well  thanks for your help.

See that in the release notes..  Wonder why the P3A can't be brought back to 1.7??

As Tim and myself have said in many other threads, the range has not been decreased.

If the power is decreased but the range maintained by some means then it is a non issure for.me, and my range most definitely has not decreased.

Unless...and I am a physician, not an electrical engineer, so bear with me,  but might decreasing transmitting power affect penetrance, I.e if I could "see" through 2 trees before, would lower power allow me to maybe only see through 1 tree?  I don't think it affects that aspect of it either...I think that is an function of frequency only, but I dunno.

The controller/aircraft link channels are between 2.400 GHz and 2.483 GHz --  https://www.dji.com/product/phantom-4/info

Again, the range is still the same.

DJI-Ken,

I see you edited your above post from "Again, the power has not been reduced" to "Again, the range is still the same."

You realize that that seems like you corrected yourself, and that it can be construed that the power HAS been reduced.

Point blank question: Has the power been reduced, in any way, or at any time during any updates?

What about this spin on it:  I can state unequivocally that my range has not been reduced with fw1.8.  Have no idea what my power output is, really don't care.  If I can get the same distance on less power shouldn't that equate to a (little) better battery longevity?

Hi,

DJI-Tim said in another thread -> http://forum.dji.com/thread-51366-2-1.html  "DJI RC power output for FCC is 79 mw, for CE is 25 mw DJI has no incentive to decrease RC power."

That basically means that the power has not been reduced right? Or is this another way to dodge the big question?

DJI-Ken Posted at 2016-5-7 02:48
Again, the range is still the same.

Ken,

I have to agree..  Was the power, in fact, reduced?  Because the converse of what you're saying also, if it has and the range is still the same, is that the range could have been increased with the old power?  Not sure how you would lower power and maintain range (and as someone put it) penetration..  :-(  Another reason to try and go back to 1.7 fw...  Please clarify..  and also, if it was a transmission power reduction, it should have been in the release notes...

DJI-Tim Posted at 2016-5-6 10:51

Tim,

In this statement you're saying the power is the same??

Ken (and Tim),

I think we're all asking for one clear statement, that being that both the power and the range were not modified in the 1.6 RC fw (and something as a counterpart) in the 1.8 aircraft fw.

Tim,

There is no reduction in power or range !

This is beginning to bother me a lot. I've never spent so much time watching a couple of forum threads.

Automatic updates can be switched off on IPad Air 2 as follows: Settings -> ITunes and Appstore -> Then under "Automatic Dowmloads" make sure you turn off the switch next to "Updates"

Ok Ken. Thanks I guess...

Can we put a lit on it? I'm exhausted.

hello there, your flight data when the rain stops will be vital to all of us .. all data collected is part of the hole which is the end result .. the fact that DJI is unaware is good news really .. that would mean once we get the data out to them as valid partners that have pertinent data they will install the necessary call ups in the next firmware release putting both pilots and DJI in good standing with the FAA working together to maintain maximum performance so maximum safety can be achieved both by the aircraft and pilot .. PLEASE  post your flight data as soon as weather provides a flight window for you...!!! ;-)

I am going to ignore the fact that some are calling me a liar or that my metters or testing methods were done in error or not valid .. so we can continue to work together and solve the issue .. pointing fingers of blame just put resolve out of reach thank you for listening and being part of this necessary process ...!!! ;-)

hello there, on pre mission flight check list I always check max altitude to make sure it is working .. I could not even reach 120 meters .. that started the testing .. which showed that the RF power had decreased from 24ma to 14ma .. or by 50% .. now if DJI is not going to recognize the data the reason has no more grater effect .. we must work together in this fast paced technology to fly safe .. listening with deaf ears is not acceptable to reach resolution or a fix it is just politics .. that is why so many pilot are getting very discouraged and doubtful as to DJIs real intentions in this class of sUAS manufacturing and customer care I started the post to be helpful to all pilots and DJI .. but I just can not or I should say it is we can not get through to DJI that this is a fact .. and we need something done about it for safety and confidence in them as our partner in public sUAS flight...!!! ;-)

Maybe your meter is bad?  Nothing has deteriorated on my bird.  Just say-in.

DJI-Ken Posted at 2016-5-7 04:49

Hello there, so then you are calling me a liar.??. or are you saying there was no intention of reducing power or range .. because like many pilots have said .. our actual range has been reduced by the firmware upgrade and if we try to go back to resolve the issue we can not bine the bird to the RC for whatever reason or are you going to tell us that is not happening either even though it is .. .WOW is this really how you are going to work thing out with your customers and actual pilots of your product ..??.. by just telling us it can not be happening and we are mistaken .. than I must tell you I have to find resolution without you or your help as you are not seeing me as a partner with good data to share but someone you don't need or you think is incapable of giving you good data or just a liar .. total frustrate with all the politics in public sUAS flight and was hopping you would value your base customers more .. instead you are just trying to ignore what we are experiencing in are actual day to day flights...!!! ;-(

Well I guess I'm done with this thread that I thought was going to be productive.  I am trained to be an objective observer, and admittedly a fancy RF measuring device SHOULD produce objective results, I believe even more that real world experience, if looked at objectively is more reliable, so, unless I got the only phantom 3 that suffered no range loss (for whatever technological reason) after upgrading, then I think it's a moot point.  Y'all have fun discussing it...I'm gonna go fly a few miles and back . I do wish I had a bigger battery to see how far this baby would really go...but I digress.

Yes just put 1.7 on a formatted SD card and do the update sequence.  Only works for p3p not p3a

"Only works for p3p not p3a"

Where do you get this info from?
It sounds dubious (like lots of misinformation spread on forums).

The firmware release notes say:
Notes:
- The firmware can be downgraded to v1.7.0060.
- Both the aircraft and the remote controller must be upgraded or else they will not link

You've heard from multiple DJI sources that the output power has NOT beed reduced.
And there's no reason why DJI would want to reduce output power.

Instead af asking if someone's calling you a liar, you should be checking your equipment and methodology to either see where you've gone wrong or be able to present proper data with evidence to back it up.
So far all anyone knows is you got a gauge to show some numbers.
Were these numbers accurate and were they showing what you think the were?

DJI-Ken Posted at 2016-5-7 04:49

hello there, your flight data when the rain stops will be vital to all of us .. all data collected ...

mdazel,

So we've heard DJI say, rather categorically, that nothing (at least to their knowledge as one of your posts inferred) was changed relative to power or distance.  You referenced my flight data which I'm more than glad to post for anyone to look at, but I'm also trying to understand what it will show?  I may be showing my own ignorance here, but is there specific information in the flight logs relative to transmissions and receptions?  When I look at the playback in the flight log, I can see that RC Control Stick movements are tracked.  Is there another (or different) file you're referring to?

Also, and a suggestion.... First, I really think you should be able to back things off to 1.7 (on the aircraft) and 1.5.8 on the RC.  I believe you mentioned you tried and couldn't re-link (which is a problem in itself and may be pointing to an issue in the RC?).  

If you can get that corrected, you could then re-produce and video the meter differences between 1.7 and 1.8 that you say you are seeing.  I'm not going to doubt your saying what you believe you're seeing and I think that DJI seeing it on your RC and Aircraft could be valuable especially if it is reproducible at will.

We have people who have had a chance to fly say they've seen no difference with 1.8 for distance..  Penetration could be different, but we have no thoughts or evidence there I recall in this thread.  Again I don't know what flight logs show, but there are some folks still on 1.7 and others on 1.8.  I still have my 1.7 flight logs as well..

From the main home page, if you press the graduation hat (upper right corner) and press it for 5-10 seconds then let go, it will take you into the downgrade menu (aircraft OFF while dong this).As for the drone. just simply extract the 1.7 fw to the card and do it like the upgrading. But P3A cannot be downgraded if its fw is 1.8 now.

Here's a link to the 1.8 fw for the Advanced.. Unlike it's counterpart for the Professional, the line of text indicating it can be brought back to 1.7 is not in the release notes... (it is there on the P3A for the 1.7 update stating it can go to 1.6)..

Understand, and I think the OP is on a professional but can't relink after backing off 1.8 (Aircraft) and 1.6 (RC).. I'd be interested in seeing a video of the meter showing the difference if it's reproducible..

That line seems to be on every other reference to FW1.8 for the Advanced.
