Bob -
You're right of course. Picking a single simplex frequency that
wouldn't step on any local toes as it's moved around the state could
be quite a chore too.
I was just looking at the 144.930/147.585 pair used for itinerant
repeaters elsewhere. In New York, UNYREPCO coordination policy calls
for 15-mile spacing with the "adjacent" 147.015/147.615 pair used by
N2IED in Corning.
