Phantom 3 Standard range mod , let's do it together...

[Ojcze Nasz]

by changing the country to BO, it should allow us to set txpower to 33dbm (1Watt !!)
I'm not 100% sure and will try after enable telnet, my phantom default is FCC mode, so I can just set txpower on the fly....much safe

I think the hardware limit is 27dBm, +3 for the antenna, that gives 30dBm which is 1 Watt.
But if you really want to try then set it to BO.
Command via telnet is

iw reg set BO

Test it and let us know. Good luck, don't burn your remote.

Well, you can't be blamed for trying to improve knowledges about this drone and its system... You did a very great job so far and we're all aware of the risks that occur in such procedure.

So now we have to think about how to proceed safely or at least in a way that won't brick devices definitely. I think if the telnet method allow you to restore config with reboot it's worth a try.

we have to modify the rcS file

Brilliant work Ojcze!

This made me wonder if the range of channels gets expanded to the extra few in the USA? Maybe you have found the '32-channel hack' for the Standard? ;-)

really though, I think you need to get out there and fly your new toy!

Have fun and safe flying!

set country to US,.it will enable fcc.mode and channel 12-14 is disabled

if set to JP, fcc mode still here, and channel 12-14 will be enabled, by using channel 14, it may less inteference with other wifi, but tx power is limited at 20dbm

I agree, Channel 14 is a non-overlapping channel at the high end of the band.
In dense residential areas with many wifi's you'll probably get better video reception on Ch 14 with 20dBm than Ch 2 with 27dBm

Channel 2 is set as default on mine. I'm thinking about changing also.
Make sure you switch your drone to JP first, otherwise it will not be able to see remote on channel 14.

To change country regulation

iw reg set JP

iw reg get <- to check.


To adjust trasmit power
iw dev wlan0 set txpower fixed 2700

my drone/remote will switch to different channel when i reboot, sometime it is channel 2, sometime channel 6
may be we need to lock the channel to 14 ?

In addition to power levels, it is also important to know how the 802.11 protocol acknowledges each received frame. If the acknowledgement is not received, the frame is re-transmitted. By default, the maximum distance between transmitter and receiver is 1.6 km (1 mi). On longer distances the delay will force retransmissions. So we can tuning "time out value" ?

Packet fragmentation can also be used to improve throughput in noisy/congested conditions.
We can use a lower MTU size in noisy conditions for better video downstream ?

PS : rts and mtu already fine tune by DJI, found iw phy phy0 set rts off and iw phy phy0 set frag 256 at rcS

Hi Ojcze Nasz. Your video on youtube seems to be gone. Is it possible to re-upload?

Keep up the great work

 

[Ojcze Nasz]

Use the russian video. He made it nice and clear.
Fckrs are lean to do some work but they're first to make a video.
Don't give him likes, he is a copy cat.

OK Guys !!! Done it right , I'm back on FCC.

I actually enabled telnet on my phantom to check
Yes, it's doable, very easy indeed. Going to test it right now.

All you need to modify is to add following at the end rc script.

I'm not sure which one is what so I modified all four of them. No harm doing all of them cuz they're most likely used in different instances of init.
However these are the files you need to modify :

/etc/init.d/rcS
/etc/init.d/rcS_ap
/etc/init.d/rcS_aphand
/etc/init.d/rcS_cli <--- probably do not even need this one...

Simply add "iw reg set US" without quotes at the VERY END of each file in new line.

Reboot and enjoy your full power device

Good luck.

Hello my friend.. can you please tell me what is the exact line or lines we should add to end of the rcS files.... now i m in FTP.. so if you can tell me now.. I really appreciate that... Thanks

SO my friend, According your video the only file we should change is "rcS" we can ignore
/etc/init.d/rcS_ap /etc/init.d/rcS_aphand , right??????? and also the only thing we need to do is change GB to OK .... Am I right my friend??????

 

[Ojcze Nasz]

Yes. This should do the trick.

I asked it because that Russian guy changes "GB to OK " in all the files bro....

Do not use a Microsoft Word to edit the file in Windows.

Do not use Windows to be more precise. There were two bricked controls so far.

In my personal opinion changing only rcS should be sufficient. However try it and test it. If doesn't work modify the other files.
I'm not sure as I first edited all of them, then I realized I probably didn't have to, but I wrote instructions so i left it like that.
Please test it and let us know.
