Maryland DMR

This is unofficial information (as in, these are my notes).

Many changes have recently happened in the Maryland region with respect to DMR.  The introduction of BrandMeister C-Bridge many of the talkgroups available have changed.  I highly recommend reading the BrandMeister User Guide as it contains much of the information needed to build your own code plugs.
