The Midland County Sheriff's Office presently operates a
Motorola Astro (tm) Project 25 VHF conventional radio system. This system
consists of two Motorola Quantar repeaters operating in the digital mode that
are used primarily for Sheriff's Office personnel engaged in Patrol,
Investigations, and Civil/Warrant service.
A third Motorola Quantar
operates in the analog mode, but is digital capable. This repeater is intended
primarily for other users not involved in the day-to-day operations of the
Sheriff's Office, but do require dispatching services. This channel is also
available for interoperability between the Sheriff's Office and other agencies
that have not yet made the transition to digital. Several simplex channels are
also utilized in both analog and digital modes for Courthouse Security, SWAT and
A fourth Quantar is used as a base station to
accommodate the Statewide Interoperability channels, including "Texas Law 1

interoperable with as many area public safety agencies as possible without the
need for additional communications infrastructure, or the intervention of a
dispatcher. This system upgrade was made over a four year period.
fifth phase addressed significant officer safety issues by adding receiver
"voters", or "comparators", which would improve county-wide handheld radio
coverage. Funding for three of these devices has been obtained by the Midland
County Sheriff's Office through Homeland Security grants. One of the devices
has been installed and west-side portable coverage has increased greatly.
Installation of the remaining two devices and funding for third device should be
completed by the end of 2006.
Through Sheriff Painter's initiative, the Department of Public
Safety and the Midland County Constable's Office has access to the MCSO
