The only issues that I have with 2.4 is that I currently own 4 72Mhz radios. 1 is 9 years old, 1 is 6 years old, 1 is 4 years old, and one is one year old.

At some point, I will begin to replace my older radios with 2.4Ghz. But I don't want to be forced to replace all of them at once. I would prefer to make the transistion via attrition. And previous radios that I owned lasted over 20 years. I realize that technology changes more rapidly as we move forward. And that I shouldn't expect to operate my current radios for 20 years. But I would hope to have at least 8 or 10 years to make the complete transition.
