Yes, I do agree 2.4ghz is an upgrade simply for the fact that the frequencies are selected by the radio and jump with interference and use. I keep a 72 around for one particular reason. I use model match and would not have it any other way. When you curmudgeons wake up and smell the coffee, you will realize it is time to move on and upward. So when are the 5.8ghz radio going to hit the market, and when is 72 frequency going to get sold to cellular phone service? If radio manufacturers don't have anything new to sell, the market dries up.
