It is all about perception though...yes, Dstar is an 'open' protocol. Yes,
anyone can license and manufacture equipment for it. So who (of the major
ones) has done it? Icom. So yes, regardless of the reality...Dstar
*appears* to be an Icom protocol. All that has to happen for that to change
is for another manufacturer to get in the game. It would *appear*
though...that this is going to remain Icom's thing for now.
