    About our site codes: You will notice that each location has a three letter site code. One controller at a location uses this code on the air to announce a change in status. For example, when Quincy links, you will hear "Q C Y Link 1 Up". When there are multiple controllers at a location, each one needs a unique identifier. At least one controller will match the location-based code. The hub controllers identify as HUB1 and HUB2. The 900 repeater at Marlborough West identifies as "MRX".
