My biggest problem with the D-Star repeaters is that they didn't make them analog compatible. Knowing as little as I do about the D-star hardware, it would seem easy enough for Icom to have done so. All they would have needed to do would have been to look at the incoming signal, see if it was analog or digital, and process it correctly.
While you'll pry my analog repeater pairs from my cold dead hands; if D-Star machines were analog capable, I'd swap every pair I have to that format tomorrow. As RB (the company) I have been asked about D-star more times than I can count. I tell people it's nice to play with, but what happens in an emergency? If Icom would have made the D-star machines analog capable, those that wanted to (and had D-star radios) could play with it all they wanted to. When an emergency arose and you had 10x as many people out there with analog rigs, the machine would *still* be useful. As it is at present, if an emergency arises, only those with D-star rigs can use a D-star machine. That concept is fine, as long as ALL of your volunteers have D-Star radios! (How many places is this the case?) Around here (Western PA) the governments bought Icom D-Star radios for RACES. I had no objection to that since those radios can be used in analog modes with analog repeaters. Now they are wanting to get D-Star repeaters for RACES and emergency use. I *strongly* object to that since they CANNOT be used in analog modes for emergencies. In my view, you'd be alienating much of your volunteer base that doesn't have the correct equipment right at the point where you need all the help you can get! Of course with the government in the mentality that they have been in the past few years, maybe that's their way of "thinning the heard." I *think* I remember someone saying that some other company had made an analog capable D-Star controller? Do any of you list members know anything about that?
