RE: Which radio?
You just reiterated my point. I said in one of my posts that people will still be using 72 MHz 20 years from now, but if you're buying a new radio now, take a good look at 2.4 GHz before deciding to get 72 MHz because 2.4 GHz is the future, not 72 MHz.
Your point about starting rumors is well-taken, but I don't think anyone is saying 72 MHz is going away any time soon (at least I didn't).
