i think you have hit on somthing here, that im also not sure of...
in a rash moment, i aquired a 2w 868 - 950mhz Vtx, and we also have a 1w Data 900 mhz Tranceiver.
If the Vtx was set to 868 or 950, do you recon that it will bleed all over the data?
We have used both with success but not together, (always testing somthing new and not putting them together as we originally planned)
is there enough room to stop the bleed over?
no expert on Radio systems
Doc.
are you meaning use 868MHz XBee for Ardupilot telemetry download?
There was a discussion here some time ago, because it seems they don't work for this. They have a duty cicle of 10%.
Is there anyone using them successfully?
Ric
The datasheet says that 40 km is the outdoor, line-of-sight range of this radio. In urban conditions it's about half a kilometer.
My further question:
what about 868 MHz ZigBee + 1,3 GHz video downlink? (868*1,5=1300)
The range should be up to 40 km LOS (or 16 km if in Italy).
(correct me if I'm wrong)
Anyway, what environment did you do the testing in? Did you have a clear line of sight? What antennas were you using?
