Hello Everybody,
I am using on my UAVs the following for transmissions (I'm based in Europe):
- RC Control: EzUHF (433MHz)
- Telemetry (APM<=>GCS): Xbee (2.4GHz)
- Video down link: ImmersionRC (5.8GHz)
I am looking into ways of "simplifying" the system with these objectives in mind:
- One transmitter less on the UAV (For multicopters, it would be easier then to keep transmitters well separated)
- mitigating interferences issues
- Greatly improving telemetry range (comparing to Xbee system)
- Freeing one frequency
After some research I found out that the EzUHF Rx from ImmersionRc is actually a transceiver (Here) which will made, from my understanding, the EzUHF system a full duplex long range link thus combining RC control and telemetry on one radio link. Unfortunately I didn't find how to implement this feature.
I wonder if somebody here already looked into it and manage to get it working
Thanks in advance for your answers
Kind Regards
Alain

Hey there,
Sorry for this very late reply, I've been side-tracked on other things lately and at the end totally forgot to answer
@ Matthew the setting I am using for now might sound overkill (on the RC side) but using 5.8GHz, we managed to transmit video over 5 km (I'm using Immersion RC diversity receiver mounted with a SkewPlannar antenna and a 7 turn Helical) , it was not done in flight though, but from hill to hill with a totally clear line of sight. Thus I reckon, it should be possible to reach greater distance than 2-3 km from the UAV to the ground (as long as there's no obstacles on the way). Anyway, that's because I'm looking into overcoming the "weakness" of the 5.8 Ghz that I'd like to have RC control and telemetry on the same frequency, hence using the transceiver capability of the EzUHF system, therefore freeing the 2.4 Ghz frequency for video.
There would be then "only" 2 frequencies in use, which simplify greatly the system I believe.
@ Arshish: unfortunately I'm still trying to find out
With Kind Regards
Alain
I definitely will!!
