"I've been living in a bit of an alternate reality, thanks to shooting video at the ARRL/TAPR Digital Communications Conferences and at some of the more esoteric forums at Dayton and other hamfests. In that universe - actually more of a future than a present - we don't have to choose which closed system we want to buy into. We don't have to carry three or four handhelds around to cover all the modes, and hope our belt is strong enough to keep our pants up (and guaranteeing a feature spot on HamSexy). We can operate a single radio that can run all the DV modes, along with analog FM.
That radio doesn't exist today, but it will."
