Mike - What a batch of good ideas! All you folks have been very helpful and I've got a batch of homework to do. The Upper New York Repeater Council is having a meeting at the Rochester HamFest on June 3 from 1 pm to 2 pm (and maybe longer if they'll agree) and I'll organize these good ideas in writing so that maybe we can start to hammer out a workable itinerant repeater policy.
