No question Dave, I just meant for me, my 12X still does more than I need for my jets and I have never had a problem with that radio, here's hoping it stays that way. I like some of the features the 28X is talking about and you're right, it's the link to your model, but like I say, I'd have to have a good reason to switch I guess. Not saying it's not worth it, but I've never even used up all 12 channels in the jets I fly haha.
