What You Should Know About a Scanner

A scanner is a radio receiver that picks up frequencies that are transmitted in a certain frequency range. These frequency ranges are called bands. Take a look at your radio. Most radios are AM and FM receivers. AM is a range of frequencies to which you can tune in and listen. FM is a different range of frequencies, located higher in the frequency range, which is also used to transmit sound from radio stations. Because both AM & FM cover a range of frequencies, they are called bands. A scanner is very similar to your radio, except that your radio is limited to only AM and FM bands. A scanner can cover many bands depending upon its capabilities.

What can you do with a Scanner?

Listen. If you ever wanted to know what is going on around you, buy a scanner. You will hear police and fire departments at work, ambulances, railroad trains, and amateur radio, taxis, and weather plus government, military, marine and business services. Certain models of scanner also receive airport communications and planes in flight.

Is a Scanner Complicated to Operate?

If you have ever programmed your VCR to tape a show, you most certainly will be able to program a scanner. In fact, it is probably much easier to program a scanner.
Do I Need a License to Operate a Scanner?
No, a License is not required to operate a scanner.

Wire Gauge and Ampacity

Facebooktwittergoogle_plusredditpinterestlinkedinmail

In order to install any electrical wire installation, the proper wire size for the application is needed. But how do you know what size wire to use? Wire is sized by the American Wire Gauge (AWG) system. Your installation will depend on a few factors. The gauge of the wire, wire capacity, and what the wire will feed should all be considered.

You’ll notice that the smaller the wire gauge, the larger the ampacity that the wire can handle. Wire ampacity is the safe amount of current that a wire can handle without getting hot or causing a fire. The following examples of devices in your home, the ampacity that they are rated for, and the wire gauge, will help you determine the right size wire for the appropriate application.

All About CB’s and CB Jargon

What you should know about CB Radios

What exactly is a CB Radio?

A CB Radio is simply a 2-way voice communication system that lets you broadcast messages to other CB users. It lets you talk from your truck, home, business, car or boat to any other CB operator on the same channel. Technically it is a transceiver. It functions both as a receiver (when receiving messages). Citizen Band Radio was created by the Federal Communications Commission or FCC in 1958. In that year the FCC authorized 23 channels for private citizen use. CB’s popularity soon congested these channels, so the FCC added 17 more channels for a total of 40, effective January 1, 1977.

What types of CB’s are there?

Base CB – Base Stations are units designed primarily for fixed position use in the home or office, on a desk or countertop. They are equipped to operate on 110V – 120VAC house current without special adapters. Though they are no more powerful, base stations have added range capabilities over mobiles and portables because their fixed position allows much greater height.

Mobile CB – Designed for mobile operation in cars, boats, trucks, tractors, planes, etc. Although generally more compact than base unit, they have the same maximum legal transmit power (4 watts). Most mobile CB’s are designed to operate on a 12 volt negative ground power supply. Some are capable of operating on a negative or positive ground system (check your owner’s guide). While most cars, on the road today are negative ground, some older cars, newer trucks and imports use a positive ground. If you are not sure which you have, check with your service station mechanic.

Portable CB – Often referred to as a hand-held walkie-talkie. It is a CB which carries its own antenna and internal power supply (batteries). Depending on its features, a portable can take several configurations with respect to internal external power supplies, antennas and microphones.

AM/SSB – The method most CB’s use to generate a voice signal is called amplitude modulation or AM. The AM signal can be divided into three segments: the carrier, the upper sideband, and the lower sideband. CB radios designed to broadcast on just one sideband at a time, as well as regular AM, are called Single Sideband or SSB. SSB equipment gives you significantly increased power output and range in sideband mode, and provides 80 additional operating channels.

Emergency CB – This newest CB two-way radio can get you help fast when you have trouble on the road. It’s small, hand held unit that plugs directly into a car’s cigarette lighter/port for emergency use, and stores out of sight when not needed.

CB Controls and Operating Features

Depending upon the manufacturer and model purchased, the CB may be equipped with a variety of controls and features which are designed to make the unit more efficient. The following lists the most common of these features along with their purpose or function.

Do I Need a License to Operate a CB?

No. Using a CB requires no special training or instruction and anybody can learn to use it in just a few minutes. To talk, simply pick up the mic, press a button and talk. To listen, simply release the mic button and listen. It’s that easy.

Is Talking on CB Really Difficult?

No, but the CB boom has been responsible for creating a colorful new jargon all its own. Most CB operators develop their own nicknames called “handles”. After about an hour or two of listening you’ll be on the air and talking like a pro.
