I see on the Futaba site where models from a 9c can go into a 9c super although something happens with model #13 defaulting to model #1? I suppose I will figure that out on my own when I sit down with it. My question here is will I be able to use models that were programed originally on the 9cSuper in my old 9c? Also will all modle memorys stay intact? I wouldn't want to put the campac in my older 9c and have it not recognize things quite right and cause a problem. I figure at the least that some models wouldn't be useable as the 9c is an 8 model radio and the 9cS is a 12 model radio plus 6 with the campac I believe. If I understand things right the older 9c would only recognize the first 14 modles perhaps. Just don't want to loose the information but also don't want to toss the old radio I want to get it repaired.
