Terms and Definitions

Frequency

Radio signals are sent as waves through the air. These
waves move up and down. A frequency is the number of
times in a certain time period, usually a second, that
these waves move all the way up and all the way down
and back to all the way up. For example: 123.450 kHz
means that the waves are moving all the way up and all
the way down and back all the way up again 123,450
times each second.

Mobile Extender Most Highway patrol vehicles on the road today are

equipped with a secondary radio system known as a
“mobile extender” or “vehicle repeater.” Whenever the
dispatcher transmits to any vehicle in the district, every
“mobile extender” in every car withing the district is
activated.

Priority Alert

Using a constant PRIORITY check of specific
frequencies in each state, the BCT-12 recognizes and
alerts you to transmissions from “mobile extender”
radios as well as from car-to-car, aircraft-to-aircraft and
other special-purpose frequencies. You receive an
audible (beep tone) and visual (flash of warning light)
alert whenever you are within an approximate three mile
radius of many Highway Patrol/State Police units.

Scanning

Scanning is the process by which your scanning radio
checks each frequency for the presence of a signal, and
when it finds a frequency with a signal, for example
someone talking on it, it stops, allowing you to listen to
the signal.

Weather Alert

Lets your scanner function as a severe weather warning
radio. With Weather Alert turned on, when the NOAA
issues a severeweather warning radio. With Weather
Alert turned on, when the NOAA issues a severe
weather warning, the BCT-12 sounds an alert tone and
youl will hear the emergency weather broadcast.
