I use a Spectrum transmitter module (X1TXN from Horizon Hobby) attached to the trainer port of my Aurora. It outputs a PPM signal to the module so I can use any Spectrum receiver including Orange satellites.
You can select in the Aurora which transmitter and model it should use.
Was a bit tricky to match the channels and tinker with endpoints etc. but it works.
Maybe this could be an option for you?
