If you have a spektrum radio (or TX module), use the satelite for the AQ and you are out of trouble. No need for PPM conversion. If you need other equippment, just bind a receiver and use it standalone (no connection to AQ beside 5V for power, +- 1 Amp max on that Recom). If you need more power, use an external voltage regulator (BEC) to power the extra receiver and its attached devices.
BTW, before using the satelite, bind it to your TX with any receiver, then unplug the sat from the reveiver and plug it the AQ. If you bind with a receiver up to 7000 series, use 10bit on the AQ side, otherwise, 8000 series and up use 11bit. Always use DSM2 modulation. AQ is not ready for DSMX yet.
I hope that helps.
