This type of broadcasting is the same kind of radio signal transmission to a large range of geographically dispersed listeners. Except that it is carried out by means of a wired line of a special radio broadcasting network. To receive such a signal the consumer uses a push-button receiver to select programs and a loudspeaker.
Wire broadcasting in the present time is not attractive to almost all advertisers in our country. This is due to the fact that the solvency of its listeners and its popularity is very low.
It is the first – third button, respectively. The main advantages of this type of radio broadcasting include high sound quality and minimal interference. The receiver is very simple and relatively inexpensive. Also, the advantages include energy independence and high reliability.
But the disadvantages of wired radio is the fact that for its work is necessary to lay branched cable lines. To listen to this type of broadcasting uses a stationary receiver, and the number of listening programs is limited.
Most new buildings today are built without wired radio. Although newly built schools and houses are not allowed by law to be handed over without it. This is due to the civil defense requirements of our state. After all, this wire radio is not only the dissemination of the usual mass information. One of its main tasks is the rapid notification of the population in the event of an emergency in the country in wartime or peacetime.
Even during the Second World War with the help of wire radio warning the entire population about the impending raids of the enemy aircraft. It was virtually the only source of information at the time. Today, these receivers must be present in all medical institutions of our capital near each bed. It will allow to inform the patients about the impending danger in time.
Thanks to the rapid development of technology and equipment, modern home receivers were able to displace stationary receivers from the market. Broadcasting by loudspeakers, which used to stand on practically every pole and building, has also ceased.
Wired radio is present in many countries around the world. In some of them it operates through the telephone line. The sunset of wired radio was provoked by the increase in tariffs for its service, unprofitability, dissatisfaction of the elderly (pensioners).
In rural areas, the poles through which wired radio was laid have long since disappeared, and the cables themselves have been stolen. The new four-channel receivers were of rather poor quality. About 25 percent of them have been returned to the manufacturer.
It is true that there is also pirate wired radio. As you know, official radio broadcasting does not work at night. This is when the pirates connect to it, broadcasting their own programs. They still find their, albeit small, audience.
