All About Scanners

A scanner is a radio receiver designed to allow you to listen to radio transmissions from the various agencies and companies using radio in your area, such as police and fire departments, ambulance services, government agencies, air, and amateur radio services.   Scanners let you scan these transmissions and are often preprogrammed with service search banks for convenience. By pressing a single button, you can quickly search those frequencies most commonly used by public service and other agencies without tedious and complicated programming.  Scanning is a growing hobby that lets you "listen in" on public radio conversations and keep up on current local events as they are happening.

Scanners are broken down by physical types and scanning methods.

The three physical types of scanners are Handhelds, Mobile and Desktop.The primary differences between them are shown in the table below. Range is dependent on the antenna used, and a handheld scanner can usually be used in a mobile or desktop environment by attaching it to a vehicle-mounted or base-station antenna.

The three basic scanning methods are Crystal-controlled, Conventional Programmable and Trunktracking. 

Early scanners were crystal-controlled.  These scanners had one or more internal slots for a crystal which allowed the radio to receive a single frequency.   Crystal-controlled scanners are not currently being sold; however, a number of them turn up in pawn shops and garage sales.   Generally, if you are looking at a scanner and it does not have a keypad or program button, it is probably crystal-controlled.    The disadvantage of crystal-controlled scanners is that they were slow to tune, expensive to set-up for new frequency/channel activity, and they can not follow the new trunked radio activity.

In the mid-80's came programmable scanners.  These use integrated circuits to allow the radio to tune to a range of frequencies and were a marked improvement over crystal-controlled scanners, which required the purchase and installation of different crystals.  Programmable scanners come with a wide range of features and capabilities and are distinguished from one another by the following features:

• the number of channels
• the frequency ranges they can pick up
• frequency band and/or service band search
• scan speed (channels per second and/or steps per second)

Cordless Phone Frequencies

Chs A - E handset frequencies are also used for baby room monitors and low power handie-talkies.
The F.C.C. has designated the 43/44MHz frequencies for cordless phones to relieve the overcrowded 46-mhz band. (Apparently the 900-mhz phones are not catching on because of the increased expense).

Airphone Frequencies

450 MHz Air-Ground Mobile Phones

Below are the frequencies for the 400MHz air-to-ground telephones found in private Aircraft. The transmissions on these frequencies are FM. Cities throughout the country have been allocated anywhere from one to three of the channels listed below. Those channel allocations are listed below. Keep in mind that not all the allocated channels may be in use in a particular area.

When monitoring these frequencies, be aware that the ground stations repeat the airborne half of the converstion, but transmit an annoying continuous tone when not in use. If you are within range of the ground station and want to avoid the tones but hear both sides of calls when they're made, you can do so by programming both frequencies into your scanner. Lock out the ground frequencies when scanning, and when a call is received from a plane, manually step up to the ground frequency to hear both sides. If you are out of range of the ground station, you will only be able to hear the plane side of the conversation. This service is used on private aircraft.
