History of Radio in Bangladesh_
Bangladesh Betar (Bengali: বাংলাদেশ বেতার) or BB is the state-owned radio broadcasting organisation of Bangladesh. It was also known as Radio Bangladesh between 1975 and 1996. Radio transmission in the region now forming Bangladesh started in Dhaka on December 16, 1939. Initially, the station was located in old Dhaka. Later, the station was relocated to Shahbag. It played an important role during the Bangladesh Liberation War of 1971. On March 26, 1971, the broadcasting center of Radio Pakistan was used to transmit a declaration of independence, which was picked up by a Japanese ship in the Chittagong Harbor and retransmitted. During the war, it was known as Shwadhin Bangla Betar Kendro (Independent Bengal Radio Station). Due to heavy shelling, the station had to be relocated several times, and ultimately moved to Calcutta on May 25, from where it would broadcast until the end of the war. On December 6, it was renamed Bangladesh Betar.
Today we have 10 radio stations running in Bangladesh. Those are_ * ABC Radio (Bangladesh) * Bangladesh Betar * DHAKA FM 90.4 * Radio 2fun | * Radio Amar * Radio Dhaka * Radio Foorti * Radio Metrowave * Radio Today * RadioGoonGoon

Types of Radio_
-------------------------------------------------
FM (Frequency Modulation) Radio
Frequency modulation, FM is widely used for a variety of radio communications applications. FM broadcasts on the VHF bands still provide exceptionally high quality audio, and FM is also used for a variety of forms of two way radio communications, and it is especially useful for mobile radio communications, being used in taxis, and many other forms of vehicle.in view of its widespread use, frequency modulation, FM, is an important form of modulation, despite many forms of digital transmission being used these days.
FM, frequency modulation has been in use for many years. However its advantages were not immediately apparent. In the early

    The radio was invented somewhere around the 1860's but Am radio wasn't invented until the 1900's by Lee Deforest. Lee Deforest was the first to use the term radio. Am means amplified modulation and was and is used for long distances. Am was the first system utilized to broadcast human voices and talk shows. Another aspect of radio was later invented by Edwin Howard Armstrong. This was referred to as frequency modulation which was a series of wave frequencies that were sent at a low amplification and when these frequencies arrived at the radio they became amplified. Fm wasn't used until the late 1920's when entertainment by radio became popular and was on the rise.…

    FM radio works the same way that AM radio works. The difference is in how the carrier wave is modulated, or altered. With AM radio, the amplitude, or overall strength, of the signal is varied to incorporate the sound information. With FM, the frequency (the number of times each second that the current changes direction) of the carrier signal is varied.…

    There are many people who have been credited with the invention and improvements of the radio. However, Lee De Forest’s work resulted in amplitude-modulated (AM) radio. (about.com, n.d.). Because the radio is a combination of the telegraph and the telephone, convergence, although not yet discovered or named, was present and effected the invention of the radio.…

    A distinct advantage that FM has over AM is that FM radio has better sound quality than AM radio. The disadvantage of FM signal is that it is more local and cannot be transmitted over long distance. Thus, it may take more FM radio stations to cover a large area. Moreover, the presence of tall buildings or land masses may limit the coverage and quality of FM. Thirdly, FM requires a fairly complicated receiver and transmitter than AM signal.…

    Audio frequency waves, which represent voice and other sounds and radio frequency waves, which carry audio waves after being combined with them. Two examples of broadcast waves are AM waves and FM waves. AM which stands for amplitude modulation, is a broadcasting method in which the carrier waves (carry the sounds of a program) are changed to match changes in the audio frequency waves. These are electric waves that represent the sounds of a radio broadcast. FM stands for frequency modulation and these waves, that go skyward, are not reflected.…

    Bangladesh officially the People's Republic of Bangladesh is a country in South Asia. The name Bangladesh means "Country of Bengal" in the official Bengali language. The borders of present-day Bangladesh were established with the partition of Bengal and India in 1947, when the region became the eastern wing of the newly-formed Pakistan. However, it was separated from the western wing by 1,600 kilometres (1,000 mi) across India. Political and linguistic discrimination as well as economic neglect led to popular agitations against West Pakistan, which led to the war for independence in 1971 and the establishment of Bangladesh, with the help of India.…

    With the introduction of continuous sine wave signals, transmissions improved significantly, and AM soon became the standard for voice transmissions. Nowadays, amplitude modulation, AM is used for audio broadcasting on the long medium and short wave bands, and for two way radio communication at VHF for aircraft. However as there now are more efficient and convenient methods of modulating a signal, its use is declining, although it will still be very many years before it is no longer used.…
