Radio Broadcasting
Radio broadcasting is transmission of audio (sound), sometimes with related metadata, by radio waves to radio receivers belonging to a public audience. In terrestrial radio broadcasting the radio waves are broadcast by a land-based radio station, while in satellite radio the radio waves are broadcast by a satellite in Earth orbit. To receive the content the listener must have a broadcast radio receiver (''radio''). Stations are often affiliated with a radio network which provides content in a common radio format, either in broadcast syndication or simulcast or both. Radio stations broadcast with several different types of modulation: AM radio stations transmit in AM ( amplitude modulation), FM radio stations transmit in FM ( frequency modulation), which are older analog audio standards, while newer digital radio stations transmit in several digital audio standards: DAB ( digital audio broadcasting), HD radio, DRM ( Digital Radio Mondiale).

CFIQ
CFIQ (640 kHz) is a commercial AM radio station licensed to Richmond Hill, Ontario, and serving Greater Toronto. The station airs a talk format and is known as ''640 Toronto''. It is owned by Corus Entertainment with radio studios and offices in the Corus Quay Building at 25 Dockside Drive in Toronto. CFIQ is powered at 50,000 watts, the maximum for Canadian AM stations. To protect other stations on 640 AM, it must use a directional antenna. Although it is licensed to a suburban community north of the city, its transmitter is about 60 kilometers (38 miles) south of Toronto. CFIQ's eight- tower array is in the town of Lincoln, in Niagara Region, near the southeast corner of Greenlane and Merritt Road. This location allows the station's signal to cover a large part of Southern Ontario beyond Greater Toronto, as well as Western New York state during the day and at night. History Early years On July 1, 1957, the station first signed on as CJRH. It was a 500-watt station ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CBQR-FM
CBQR-FM is a Canadian radio station, broadcasting at 105.1 FM in Rankin Inlet, Nunavut. It is a station of the Canadian Broadcasting Corporation. History The station launched in 1971 when it began broadcasting as CBQR on 1110 kHz. In 1973, CBQR moved to 1160 and remained on that frequency until it moved to 105.1 MHz in 1987. Local programming CBQR-FM carries the Nunavut regional radio service of CBC North, much of which originates at CFFB Iqaluit. The afternoon program ''Tusaajaksat'', which focuses on the Kivalliq Region, originates from CBQR. Some of the CBC North regional programs air in both English and Inuktitut, others are only in Inuktitut. The station also differs significantly from the main CBC Radio One schedule. ''Qulliq'' airs until 9 a.m. Central Time, and is followed by abbreviated broadcasts of '' The Current'' and '' q''. In the afternoons, programming in Inuktitut, including ''Tausunni'' from Iqaluit and ''Tuttavik'' from the CBC North bureau i ...

Call Sign
In broadcasting and radio communications, a call sign (also known as a call name or call letters—and historically as a call signal—or abbreviated as a call) is a unique identifier for a transmitter station. A call sign can be formally assigned by a government agency, informally adopted by individuals or organizations, or even cryptographically encoded to disguise a station's identity. The use of call signs as unique identifiers dates to the landline railroad telegraph system. Because there was only one telegraph line linking all railroad stations, there needed to be a way to address each one when sending a telegram. In order to save time, two-letter identifiers were adopted for this purpose. This pattern continued in radiotelegraph operation; radio companies initially assigned two-letter identifiers to coastal stations and stations onboard ships at sea. These were not globally unique, so a one-letter company identifier (for instance, 'M' and two letters as a Marconi sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clear-channel Station
A clear-channel station is an AM radio station in North America that has the highest protection from interference from other stations, particularly concerning night-time skywave propagation. The system exists to ensure the viability of cross-country or cross-continent radio service enforced through a series of treaties and statutory laws. Known as Class A stations since 1982, they are occasionally still referred to by their former classifications of Class I-A (the highest classification), Class I-B (the next highest class), or Class I-N (for stations in Alaska too far away to cause interference to the primary clear-channel stations in the lower 48 states). The term "clear-channel" is used most often in the context of North America and the Caribbean, where the concept originated. Since 1941, these stations have been required to maintain an effective radiated power of at least 10,000 watts to retain their status. Nearly all such stations in the United States, Canada and The Baham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
