One form of radio that is commonly used by a lot of people in different departments today is the CB Radio. CB Radios, or otherwise known as Citizens? Band Radios are two-way radios that can both receive and transmit content (communication) from one party, to another. It first came in to the scene on the early 1900?s. Unlike other radio equipment you can see today, CB Radios before were only able to cater one transmission after another in different 40 channels that ranges from 27 MHz or 11 m band.

The use of radio devices were highly appreciated and amplified on the 70?s during the oil crisis in the United States, cargo personnel and truckers used it to contact other people in the line if ever they would find a site with gasoline supply.

Because of this a lot of people in those times (specifically film producers and directors) were charmed by the massive effect of radio that led them to creating both fictional and true story movies that highlight the use of the said instrument.

With the generation today, the young ones are very much into the World Wide Web. Some of them are fond of indulging themselves with radios too in the form of walkie-talkies. Some toy companies produce walkie-talkies for the sake of fun and enjoyment of the young ones, but nevertheless they?re functions are still similar to the ones used on firms, private sectors, and a few departments mentioned earlier.

Often times, many people perceive radios as simple machines or instruments that works when a receiver and a transmitter would exchange communication, but how does that happen? Satellite radio is a digital radio signal that is incorporated through one or more satellites, making it more attainable in wider areas than the usual FM stations found in most common places. FM Radios are used by many people who use a network of local repeaters to broadcast a program in a wider geographical area. Same with the newly developed radios of today, they too need repeaters to disseminate broadcasts from one party to many, it works just like in the same manner.
