So with my DJI rigs I'm basically using RMRC transmitters at 1280Mhz just to get live audio, but my DJI video range would still always exceed my 1280 audio range a little bit. I finally found a Lawmate RX-1260 for cheap on ebay cause I kept reading old comments on forums saying "Get a Lawmate." For the first time my audio range exceeds my video. In these tests there was no audio breakup I could hear at any point. My only chance of that before was a wide open area with little obstruction. Either the Lawmate has a much higher sensitivity or the 6+ receivers I've tried before were all trash. RMRC advertises a custom tuner with a better SAW filter but I had to strain to really notice differences in reception between it and any other random lookalike receiver.
I also tested the 1280 video using the Lawmate and while it was better, I still consider the O3 far superior. It still seems to penetrate/bounce better when it comes to giving clear image. The noise rejection makes that possible even though the 1280 wavelength has superior penetration. So the Lawmate receiver makes it possible for me to mod a setup to throw less noise from the fans and allow me to hear speaking voices at range. Right now the fans drown it out making it hard to hear unless someone is speaking loudly into the microphone. With the Lawmate and a quieter setup I can put another radio on the truck for 2 way communication.
So after some months of testing I still believe DJI digital is still far superior to 1.3G for FPV. It seems like 1.3G can get impressive range with expensive patches and big wide open areas.. but then if you just wanted to sit in the car with a small omni and drive around, you're probably getting a fraction of the range and there will be a lot of noise in the video much of the time. I have enough trouble as it is driving fast with HD video, so these guys hauling ass with analog feeds at long ranges are pretty much just throwing up prayers that there isn't some small thing they don't see on the road. The only downside to the DJI still seems to be no audio but now I feel like I have that all figured out. I still use the same portable RX+speaker setup that I bring with me when doing DJI FPV but just swapped out the RMRC receiver with the Lawmate. I'm also going to try one last TX that's 2W max, so maybe paired with the Lawmate I might finally get some 1.3G FPV video going that's actually worth it.
