Well, got ORQA with TBS Fusion, and thought that it is something like software / firmware glitch, but when I've opened googles, I was surprised..
Everything done quite great, but the VRX board... guys at ORQA, how can it work??))
I got 4 broken pins there. Sympthoms are - random channel switching / lossing video for 1 second randomly and etc..
This board designed badly.. All the force when you attaching antennas and tightening them - laying down to SOLDER pins... For sure they will broke, it's just a question of time...
So guys, just resolder them - and your modules will work good again... for some time... but the design of the VRX board is quite not rock solid - as it could be.
I've repaired that by myself.
!! Be ware - that if you will do it like me - you will loose your warranty !!
So better ask ORQA support for the fix.
