Possibly. The three sites would be for different geographical coverage. They
could either transmit everything from each area into each of the other areas
or they could do something less.

You'll have to determine if you can receive each site. If you can receive
each then plug each into a separate bank in your scanner. Listen to each and
determine if they are identical. If you will be travelling into each area
frequently you may want to use all three anyway.
