Radio Sites
Radio broadcasting from radio sites is considered as a one-way communication of wireless transmission to reach the captive audience. Audio broadcasting can be done using a number of platforms including but not limited to cable radio, satellite radio, streaming media and television networks. On top of the commercial radio there is also amateur radio and this is normally tapped by private individuals for private purposes, education or entertainment. There was a time when the first radio stations worked on the concept of radiotelegraphy. It is said that the first broadcast happened in 1906, on a Christmas Eve. The broadcast which was facilitated by Reginald Fessenden is under dispute. A more commercialized broadcasting was started by Charles Herrold. After some time, those interested in broadcasting started building their own receivers. A number of firms and individual started broadcasting, for example the PCGG started in 1919. In the United States, the first official licensed broadcast came from KDKA. Outside of the United States, a prominent broadcaster during the early years was Radio Argentina.
Different Types of Radio Broadcasts
Shortwave
This is primarily adopted by broadcasters that are sanctioned by the state or tapped by religious groups and organizations in order to spread the evangelization.
AM Broadcasting
This type of broadcasting is considered as one of the earliest forms of broadcasting. Known as amplitude modulation, this will refer to the tweaking of the amplitude. The medium-wave and the long wave bands are normally used for this type of broadcasting. The most popular approach to broadcasting is to use the medium-wave band. In Europe, it was common for stations to use the long wave. With the growing popularity of FM radio in the United States, there were some broadcasters who made use of the AM band to take advantage of the growth. One of the best things about the AM band is that this is easy to detect. There is no need for advanced equipment in order to pick up the signal coming from an AM station. In North America, AM stations are available from 530 to 700 kHz. This was expanded to accommodate nine more channels. A disadvantage of this type of broadcasting is that this can be affected by storms.
FM Broadcasting
This will refer to frequency modulation and can be checked at 88 MHz to 108 MHz. This is the standard followed in all regions, except in Russia and Japan. The development of this type of broadcasting can be attributed to Edwin H. Armstrong. This was developed as way to address interference. This type of broadcasting is known for better fidelity. In the United States, the first use of this approach to broadcasting was made possible by Yankee Network. The official use of this broadcasting approach happened in 1939. The modern use of the frequencies from 88 to 108 MHz actually started after the Second World War. This is a popular form of broadcasting and covered by Radio Market Rank survey.
Pirate Radio
This is the form of broadcasting that is not covered by regulations. This can be commercial in nature and can be supported by highly targeted advertising.
Another type of broadcasting is terrestrial digital radio.
