Boston Fire uses MDC1200 and passes the IDs through the repeater. (Boston PD seemingly uses it but strips them out.) I like to set up aliases as I hear IDs so I know who’s talking. This is an incomplete, and absolutely unofficial, list.
For readability, I am keeing MDC characters lowercase, since a ‘B’ looks a lot like an ‘8’, and a ‘D’ looks a lot like an ‘O’.
