Montgomery County (MD) MCFRS Radio Aliases

From The RadioReference Wiki

Montgomery County Fire & Rescue Service (MCFRS) Unit Aliases & Radio IDs

This contains a subset of the total MCFRS radios in the system given the number of IDs that the Uniden XT series scanner can handle in one system. I have included the ones that interest me.

As the units and radios move around the accuracy of this list will slowly degrade. When the accuracy gets to the point that it is annoying me I will update the list.

      • As of June 2011, MCFRS has switched to APX 7000 & 6000 Portables and 6000 Mobiles, so as a result this list is likely out of date.
