Rockville Options for Police, Fire and EMS Scanners.
The Maryland State Police operates primarily a VHF low-band conventional radio system which can be monitored on any scanner including basic low-end models. Other state agencies also operate conventional radio systems.
Montgomery County operates a Motorola trunked digital radio system for sheriff, police, fire and EMS radio communications. The best Montgomery County scanner is a digital police scanner model which will also work on non-digital and non-trunked radio channels. Rockville, Germantown, Gaithersburg, Takoma Park, Chevy Chase and other communities also operate on this digital trunking radio system for public safety communications.
