OK I tried to add a 900 to my jet and now all my RX don't work. I plugged into E1 just to see if the radio would see it. I then watched one of Harry's video and it showed how to bind the 900 so I did that. I have a new DS 16 but only had it for 2 weeks now so I'm pretty new with this radio. All my RX on 3 models I built now have a list of numbers with an X and then a N.A. next to it instead of saying rex 12 or 7. What did I do Lol
