You will need to program FIRST as UMES is not used for public safety (or much of anything) anymore. You can disable (Avoid) most of the sites on the system that are not nearby if you never travel. The sites that you want to keep active are Caroline Simulcast, Federalsburg ASR, Talbot Simulcast, and probably Queen Anne Simulcast. Keeping these sites active will enhance the probability of hearing the traffic of interest, assuming that you can receive all these sites at your location. There are other factors that can influence what you will hear, but it gets complicated. Also understand that most Sheriff's departments on the upper Eastern Shore have decided to encrypt their communications, so you won't be able to monitor them. MSP does not encrypt their routine comms, nor does NRP.
