So why own a radio scanner? The terms a radio scanner
or a police scanner generally refer to a communications receiver
designed primarily to monitor VHF and UHF car radio systems, except, for example, a receiver used to monitor international short-term transmission. More often than not, these scanners can also go with different types of modification (AM, FM, WFM, etc.).
The first scanners were slow, bulky and expensive. Today, modern
microprocessors allowed scanners to store thousands of channels and
monitor hundreds of channels per second. Recent models can follow
trunked radio systems and decode APCO-P25 digital transmissions.
Manual models and desktop models are available.
Scanners are often used to control police, fire and emergency medical services. Radio scanning plays an important role in the areas of journalism and criminal investigation, as well as in the recreation of many people around the world.
Fundamentals of the Radio scanner
Scanners usually work in three modes:
* Manual scan
* Search for
Features of Radio Scanner:
Many recent models will allow you to scan the specific DCS or CSPSS code used on a specific frequency if you had multiple users. A memory bank can be allocated for air traffic control, another for local maritime communications and another for local police frequencies. These can be activated and deactivated according to the user’s preference. Most scanners have a weather radio band, which allows the listener to participate in weather radio transmissions from a NOAA transmitter.
Some scanners are equipped with Fire-Tone out. The fire confirms the tones of the quick calls and acts as a caller when the correct sequence is detected. Modern scanners allow you to enter
hundreds or thousands of frequencies through a pad and store them in different ‘memory banks’ and can scan at a fast speed due to modern microfiches.
Active frequencies can be found by searching the Internet and frequency reference books or can be found through a programmable scanner search function. An external antenna for desktop scanner or duct antenna for manual units will provide superior performance than the original equipment provided by the
Uses of a Radio Scanner:
Radio Scanner fans of automatic racing, aviation enthusiasts, emergency service personnel out of service and journalists use scanners. There are many scanner clubs to allow members to share information about frequencies, codes and operations. Most have an Internet presence, such as websites, email lists or web forums.
