Sunrise Radio

Sunrise Radio is the world’s first 24-hour commercial Asian radio station, focusing on entertainment, music and news from the subcontinent. Launched on 5 November 1989, it made history as the first 24-hour radio station specifically for the Asian demographic and played a pivotal role in integrating the Asian community into the UK. Today, it is the number one commercial Asian radio station in London and broadcasts on 963/972AM, on DAB and online.

Tony Lit was appointed Managing Director in September 2014 and Gurdev Jassi was appointed Chairman in April 2014.

Transmission

Sunrise Radio currently broadcasts on 963 kHz and 972 kHz and Digital Audio Broadcasting (DAB) to the London TSA (Rajar Target Survey Area). It also streams live at http://www.sunriseradio.com.

When Sunrise Radio first launched, it broadcast in west London on 1413 kHz but later moved to 1458 kHz from the Brookmans Park Transmitter north of London.

The station ceased broadcasting on Sky on 27 February 2013, followed by Virgin Media on 1 March 2013. Its DAB outlet went silent upon the cessation of its service on 1458 kHz on 4 February 2014, but is now running again.

Sunrise

Sunrise or sun up is the instant at which the upper edge of the Sun appears over the eastern horizon in the morning. The term can also refer to the entire process of the Sun crossing the horizon and its accompanying atmospheric effects.

Terminology

"Rise"

Although the Sun appears to "rise" from the horizon, it is actually the Earth's motion that causes the Sun to appear. The illusion of a moving Sun results from Earth observers being in a rotating reference frame; this apparent motion is so convincing that most cultures had mythologies and religions built around the geocentric model, which prevailed until astronomer Nicolaus Copernicus first formulated the heliocentric model in the 16th century.

Architect Buckminster Fuller proposed the terms "sunsight" and "sunclipse" to better represent the heliocentric model, though the terms have not entered into common language.

Beginning and end

Astronomically, sunrise occurs for only an instant: the moment at which the upper limb of the Sun appears tangent to the horizon. However, the term sunrise commonly refers to periods of time both before and after this point:

Radio edit

In music, a radio edit is a modification, typically truncated, to make a song more suitable for airplay, whether it be adjusted for length, profanity, subject matter, instrumentation, or form. Radio edits may also be used for commercial single versions, which may be denoted as the 7" version. However, not all "radio edit" tracks are played on radio.

Editing for time

Radio edits often shorten a long song in order to make it more commercially viable for radio stations. The normal length for songs played on the radio is 3 to 4 minutes. Occasionally, the song will simply fade out earlier, common on tracks with long instrumental endings. For instance, the radio edit of 'Heroes' by David Bowie fades in shortly before the beginning of the third verse and fades out shortly before the vocal vamping at the end of the song. Another example is B.o.B's song, "Nothin' On You" featuring Bruno Mars, whose radio edit skips the first 5 seconds & starts with the 6th second in which Bruno Mars starts singing the first chorus. The second half of the first chorus is sometimes skipped, along with the last 24 seconds which is the normal fade-out part in which B.o.B says, "Yeah, and that's just how we do it/And I'ma let this ride/B.o.B and Bruno Mars", and the radio edit ends with the fourth and last chorus with an earlier fade-out. A 3rd example would be the song, "The Man" by Aloe Blacc, in which the radio edit skips the "I'm the man/Go ahead & tell everybody/What I'm saying ya all" part & the first 10 seconds. Also, the 3rd chorus of the song is shortened. However, many radio edits will also edit out verses, bridges, and interludes, such as the original single edit of "Piano Man" by Billy Joel which substitutes the end of the third verse for the ending of the second verse. Another example for this case is Justin Timberlake's "Mirrors", where the radio edit cuts the entire "You are the love of my life" part.

Radio

Radio is the use of radio waves is to carry information, such as sound, by systematically modulating some property of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form.

Radio systems need a transmitter to modulate (change) some property of the energy produced to impress a signal on it, for example using amplitude modulation or angle modulation (which can be frequency modulation or phase modulation). Radio systems also need an antenna to convert electric currents into radio waves, and vice versa. An antenna can be used for both transmitting and receiving. The electrical resonance of tuned circuits in radios allow individual stations to be selected. The electromagnetic wave is intercepted by a tuned receiving antenna. A radio receiver receives its input from an antenna and converts it into a form usable for the consumer, such as sound, pictures, digital data, measurement values, navigational positions, etc. Radio frequencies occupy the range from a 3 kHz to 300 GHz, although commercially important uses of radio use only a small part of this spectrum.
