<div>Thanks for the info Bob - I remembered reading that and wondered if it were still true. I guess that's why they are finding that D-Star doesn't have the range first promised? At a D-Star seminar last yr there were saying the D-Star range would be greater than a comparable voice FM repeater, but I am hearing lately they are finding that not to be true... range is a good bit less.
