Not a ton of sim time, still learning fully so high possibility I did it wrong.

Saw the title and assumed this would be another āhold down the sticks until the drone runs out of signal or batteryā video that would just boil my p*ss. But no, finally a range test I can appreciate.

Thatās more like it - p*ss well and truly boiled

I wonder if it could be argued that the enabling the new picture-in-picture mode on the Goggles 3 does away with the need for a spotter 
(note: absolutely not suggesting it doesā¦ just wondering if itāll ever become an option for those of us with partners who arenāt jumping up and down with excitement at the thought of standing in a field watching them fly a drone)

it wonāt be acceptedā¦ no redundancy and limited field of view
Sameā¦ Iāve only got one working eye and it needs a pretty strong prescription.

Ok after a massive amount of testing Im pleased to be able to share something around the ham file on the DJI Avata 2.
Initially it was found that the ham file was not working on the Avata 2. This was based on my own initial testing both of the expected behaviour, RF analysts as well as reports from others.
Today I have learnt a massive amount more and it seems there have been some red herrings thrown into the mix from DJI thatās caused some confusion and while it is actually the case now the ham file is working itās not in the same way as before and we donāt know if DJI actually fixed it with the latest app and flysafe database update.
FCC Users - For you nothing has changed and the ham file increases the amount of channels available when in manual channel mode and this works as before. The RF output remains the same.
CE Users - This is complicated but
On the Avata 2 I can confirm the ham file will increase the RF power level to what appears to be the same as FCC mode. There is no absolute matter of fact way to measure the RF output however I can confirm itās reflective of FCC mode and as such should be classed as such.
However the ham file does not actually appear to put the Avata 2 into FCC mode its self. It does not allow for manual channel selection for CE users and it still allows the Avata 2 to use the 5.2Ghz band even with the ham file. BUT as stated above it does increase the 5.8Ghz RF output to FCC level and I expect it to do the same in 2.4ghz though I have not been able to confirm 2.4Ghz levels at this time.
Itās incorrect to call this a FCC hack as really itās not and today the ham file on the Avata 2 unlocks some FCC behaviour but not all of it.
While I cannot confirm this my self there are also solid reports that it also unlocks the speed limits for CE users as well, however so far I donāt appear to be restricted in the U.K. so I have not been able to confirm.
I can also confirm it works with both the RC Motion 3 and FOV Remote 3, it remains persistent on reboot and works fine with DJI Fly. It does not require applying again unless you reset your goggles/drone or connect to assistant 2.
For CE users who do want manual channel selection today the only known solution is either the drone tweaks App or the Drone Hacks App.
Just to add a final thing to this O4 is infinitely more complex from an RF point of view than O3. Some of the garden paths I was led down was because itās dramatically more dynamic in how it pushes is RF power now and Iv actually had to force bitrate drops to start to see power levels change. There is also some really unexpected thing in the different bandwith modes as well for instance 20Mhz modes have higher power available than 50/60Mhz and this also caught me out. Itās been a task of digging though the FCC docs and doing Spectrum Analysis to really start to understand it. Tbh a video on this is likely going to be 3 hours 
There is updated content on this all coming shortly.
Thanks
Mad.

Wow this is a great update to your testing and overall looks like good news that we can get FCC power levels with the ham file. I see this as a bonus to the already advanced behaviour and range/penetration of O4.
Iāve got nothing empirical but I live in a rural location with very little in the way of wi-fi interference. Iāve just put the ham file on my goggles 3 SD card and I must say the range and penetration for the Avata 2 have improved dramatically for me.

Flying around my property I would get some significant break up in the video signal at certain areas where the signal had to penetrate through several brick walls. I think it went down to below 10Mbps but more importantly it obviously wasnāt of great quality. The same test now delivers between 50 and 60Mbps and there is no video break up.
-
Flying out towards the sea from my property (about 2.5 km away) would result in massive dips to 1Mbps followed by short recoveries to about 15Mbps (switching bands I presume), but I could not quite reach the sea without the video breaking up. Today I could reach the sea and get nowhere near the same dips, I think it was still around a consistent 15-20Mbps with no video break up. It is very windy today so I had to fly back immediately and landed back home with 11% battery left.
So overall Iām even more pleased with the performance on the Avata 2 and O4.

Just had this drone delivered yesterday and applied the ham file. Need to carry out some testing in a low noise environment as I didnāt get fantastic performance flying from the garden.
Notice that the speed is limited to 16m/s in sport mode using the motion controller but I hear thatās possibly by design and you need the FPV RC3 to go faster.
Hi @13Kay, it looks as though youāre quite new here 
Why not nip over to the Introductions page, and say hello properly and tell us a bit about yourself. 
Thank you. Posted!
