I have single operator system, and am looking into upgrading to Radian, and dual operator system. Specifically I am looking into setting up using the Spektrum satellite receiver. Under my single operator system, I currently activate the remote shutter off Aux 3 from my DX-8. With the radian and dual operator system, in order to have my camera operator activate remote shutter, can I simply use the AR8000 in tandem with satellite receiver to plug my remote shutter into Aux 3? If not, what do you recommend?
