Ian, just a heads-up. When doing the ham full power test the reason the noise floor across the whole band being viewed by the specan is going up is because your saturating something in the receive chain of your specan. It's going nonlinear. Put a 10-20 db pad on the input and see if you get the same results. I think you'll find things look much nicer and is actually representative of what's being transmitted at full power. Keep up the good work! ~pk

Glad you pointed this out. I do indeed put air-units on some planes without flight controllers. This would have caught me out, had I not known. Cheers for that.

Fascinating indeed. Thanks a lot for testing, Ian! 😃 Stay safe there with your family! 🖖😊

The ham hack works like a champ on the newest googles v2 and O3 air unit. Thanks a bunch for this information.

Thanks for all the findings, it was very interesting to watch now that I am setting up my O3 and my V2s.

Did you figure everything out ok?

Nice work 👏 👌 👍

well done

So just to confirm once the cfg files is placed on an SD card and more channels are available (higher power unlocked when the O3 or Avata is armed/flying) can you just leave it in auto for channel selection? DO you still get the same benefits rather than having to txt which channels are best manually? Keep up the great work!

Thank you for this very interesting and very detailed video. I understand that the transmission power of the Air unit 03 is 1W in FCC mode and 25 mW in CE mode. I want to know if the Goggle 2 are only a receiver if they are also a transmitter? If the Goggle 2 are a transmitter, what is their transmission power in FCC mode and in CE mode?

Great info! I need to get an 03 unit and find out what happens or if it even works with the TBRC OSD boards. The way our board works is essentially sending an arming code via MSP to take the system to max power on the original system perhaps it will do the same. Now I am wondering since Wezley has taken the goggles 2 and 03 airunit out so far if the required firmware update to make the V2 goggles play together with the 03 airunit if it also ends the 13.3km hard limit in the previous version airunits. LOL this shit makes my head spin somedays. :P

I struggle a bit trying to see the mouse while you move it, Could change it to a bigger arrow ? Thank you so much for your videos

Can you do a tutoriaL on connecting flight controller and getting msg settings and canvas mode setup? I’m stumped

i love how you dont need to use a flight pack to update the 03 on the computer the 03 does not even get warm on updates = )

Is it still working on the latest goggles V2 fw 01.06.0000 and O3 with latest fw?

Does this also work when using an old air unit/vista with the goggles 2? Compared with old air unit with fcc in combination with the v2 goggles. Thatd be interesting 🙏

Ian, is it the same for vista and old air unit with just the file on the goggles or do i drop the file on them like the naco hack?

8:20 Wait, is it just swamping the entire spectrum there? So this system won't work at all with friends flying other systems - eg one person flying O3 and the other flying HDzero? Edit: Also, odd that we don't see it again in the "Testing" section of your video?

I put Naco as well as Naco pwr and the ham on my memory card in my goggles and my avata and all my vista's so everything has all 3. Any issues with what iv done?

Worked like a charm. Instant range.

Cool that you already tested the "goggles walk away to invoke dynamic power" test (which I was thinking about). If the weather stays as crappy I will try to test this anyways here to confirm. bummer that the O3 needs arm signal to go to full power. I thought we are passed the phase where we need salvaged old Fcs for the Vista backpack to just see Volts (as I did for non FC planes). Now as I understand the O3 can display input volts WITHOUT the need for an FC - but it needs MSP arming command ;)) one step forward, one back :) Have you tweaked the live image of O3 on Goggles V2? Or did you "just" fly with Goggles2? In my comparison the Goggles V2 look quite dark with O3 compared to Vista. And I wasnt even using 120fps mode.... greets, Mario

I believe you still need an FC to get O3 supply voltage. I’m trying ways to get full power without an FC too.

Very interesting! Slowly but surely we are getting more insight into the new O3 system. I have to ask. When we update our Vistas and Air Units V1 to be compatible with the new O3 Goggles 2 are the Vistas and Air Units V1 working with V1 Goggles after this update like before? I Hope because than i can use the new Goggles 2 as daily and my old V1 Goggle as spare or for friends and spectators.

Hi Ian, What I'm always wondering is does it make sense to use only certain channels when the unlocked Vista or O3 gives you the additional channels in order to have stronger signal but stay at least in the right frequencies in CE countries. I live in Germany and since I unlocked everything I often think of minimizing the risk with no effort. I'm always flying alone and I don't care on which cahnnel I fly.

How do you do the ham file

Thanks for the video. Very useful information, However..................

Allright guys. I need to apologize. the Ham hack still works. There was a series of mistakes on my side after I purchased the RC2. When I tested the mini 3 I noticed that the penetration was less than usual, then I tested the AVATA, and the penetration was the same. So I was wondering, What on earth happened? So then I removed the HAM file, and then I retested penetration and it was the same. But today after spending the weekend changing firmwares on all my devices, and testing and what not. I FINALLY resetted the goggles 2. AND ONLY THEN I SAW THE TRUE CE LIMITS. And they were terrible!! Much worse than what I was used to. SO Then I wondered why the penetration wasn't the same. So I went on my recordings to see when was the last time I flew here with the AVATA, and it was last month when there was less vegetation... Im so relieved to know that I didn't spend thousands for nothing. I was already putting things up for sale :-). Again sorry to all for the FALSE ALARM. Now it's super awesome I love the RC2 motion controller, much better than the sticks for both drones and I only hope that permit the full 500m height limit now for the mini 3 when using the motion controller like they do for the avata PS HAM file also works for mini 3 when used with RC2

Very interesting. Do you think if while activating/updating the O3 Air unit in Europe but using a VPN in the US you'd get it to FCC mode? How did you get it to "Proper FCC" mode at 11.50 in the video?

Thanks for your video. Just to make sure: ham file really cranks up the power much higher than CE so we can call it “FCC” hack. Not sure if i got correctly “low power mode” - this seems to have nothing to do with the signal strength/power and works independently from arming command (which in fact increases the actual power to a full whack) so what does it actually do? Is is to preserve the battery at the cost of picture quality? So in simple words: if i want the best range and best picture quality I should put the ham file on both ends and disable “low power mode” on goggles, am I correct? My config is o3 and v2 goggles. Thanks in advance!

Hi, I live in New Zealand, so CE mode is about 25 mW, I can only fly the dam DJI FPV about 250 - 300m away before I start loosing signal. So the Ham file is going to make a big difference. Now do I also have to put the Ham file on the drone? Since the V2 goggles will put out more power, but the drone also has to increase power back to the goggles for video. This is where I can not find any info about increasing the drones power back. Or am I still going to be restricted from low video signal back?

I fly planes with no FC for aerobatics and long range cruising using the old DJI system where you could set the system to "auto temp control off" which gave the full power you selected once you powered up without needing to arm the system.

@@PuppetFPV Hi. I have the 03 air units and the new goggles 2. I can confirm that when you switch low power mode off in the goggles, although the bit rate increases it does not go to full power and you have limited range. It only goes to full power when the system receives an arming signal. This is no problem with drones with a FC, but I fly planes without a FC so have used a very clever Arduino board mod to send the arming signal which also starts the recording. The instructions for this can be found by searching ramiss Arduino dji. It's quite easy and I know nothing about Arduino LOL.

Hello Ian: Please forgive my noob/layperson/dullard question here. Ive a new avata, goggles 2, and motion controller. Due to poor range for video transmission i sought ways to extend range and found my way to your Sept 6th “DJI Avata & FPV Drone - Free FCC Hack” video. So last night before installing your Ham hack onto my SD card i checked up on your channel for an updates i should know of and came across this video, which i viewed. Again please forgive my dullardiousness, but as of now, is the Ham hack you described in september still likely to give me extended video range for my goggles 2 video transmission [ loss showing up as the ever decreasing “HD” signal bars in my goggles 2 display], or does all the testing youve done mean that i shouldnt bother as there is no power increase for transmission of HD video signal from drone to goggles2? And if that tragedy is true, is there anything else i can do to get extended range? Thanks much.
