First off, I have a PRO-106. This will be easy for some of you and will help me out dramatically. I just moved to and area (Savannah, Ga) (Chatham County, GA) which has a multi-tower system, three big, one little to be precise. The control channels on each tower are different, and I believe it does not simulcast, not positive though because I don't really know how to tell. First question, how do I tell if a TGRP broadcast simulcast, on first available tower out of four, or on just one specific tower? If a TGRP broadcast on a certain tower, does that mean for each TGRP I have to make a dupe object out of it for each of four towers to see which one is broadcast out of? That would take years, Savannah has a lot of TGRPs? If a TGRP broadcast on first available towers, do I have to have 3 or 4 objects per TGRP to cover all the towers? I think you can see why I'm pulling my hair out. I moved from a simple single tower trunked system of a fairly small town into this mess. What is my first step? How do I find out which TGRP belongs to what tower, if it is not simulcast? How do I set this thing up? Thanks a million for your time and help.
