im not opposed to the discussion at all, I think it's interesting, but the only reason all of these people would be running two amps and the companies selling them has to amount to something. It cannot be for the very small profit, while this is a very small community and the ones like us going for range/better signal is even smaller, it wouldn't be much of a scandal. I'm open ears, either way. I just think two amps is better then one from all the reviews I've read.
so what is your set up then? how are you running your rig?
I run one of the newer style gold 3W amps, and usually the FPVLR v3 eliptically polarized antennas. I also have an original itelite patch antenna which I occasionally use.
I ordered my P3P shortly after launch, so it's an original model and I have the GL300A controller, though I also have another GL300B as an unmodified spare.
Have about 27 in-air flight hours on my bird and have covered about 200 miles. Have flown in many locations, and even done two trips abroad with it. Zero crashes, zero issues at all in fact (minus a single mid flight 5 second compass error), and while I did have the dreaded stress cracks at about 30 flights in, I replaced the shell myself, and have not had any structural issues since.
I also fly a hacked up P2V+ modified with my own special sauce wifi extender, and a H4-3D and a Hero 4 black.
Dji was my entry to the RC world, so I'm not a seasoned veteran, but I do have a little experience under my belt.
When I ran my dual amp setup, back with the black 3W sunhans, I noticed that after a while, without any modifications to the controller, or even the connections themselves, I went from two blinking blue lights, to one. But it got even better, disconnecting one of the amps power connections (back when both were blue) on the Tx port, would make the other one stop blinking as well. But if you pulled the power on the Rx amp, nothing changed, aka still blue, on the Tx amp.
So, wtf is going on? My guess was this:
Cross talk! The Tx amp is throwing out so much RF, especially for sometimes not overly well shielded cables/connectors, it was actually bledding over into the Rx side. Hence... The Rx amp was "hearing" the Tx signal from its own same controller, and blinking.
Notice how the amp led patterns don't change when the drone is on or off? Isn't that strange? Since the led on the amp *should* be reacting to that incoming lightbridge signal? But it isn't. It's reacting to the output signal from the Tx channel right next to it.
If you are only seeing one amp blink, you're probably using higher quality cables/connections and/or you took care in installing your controller connections and cable routing, and managed to minimize the crosstalk.
Like I said.... More empirical data is needed. I still have my older black amps, and tons of cables, connectors, and some spare antennas, and my rf explorer can also act as an rf noise generator... So if I have some time this weekend, I'll do some investigation and document my findings. Then I'll open up a new thread, and see if we can't get to the bottom of this whole question.
