162-538: WBZY (105.7 FM ) – branded Z105.7 – is a commercial radio station licensed to Canton, Georgia , broadcasting a Spanish CHR format. Owned by iHeartMedia , WBZY serves the Atlanta metropolitan area . The WBZY studios are located in Atlanta, while the station transmitter resides in the nearby suburb of Marietta . Besides a standard analog transmission , WBZY broadcasts over two HD Radio channels, and

324-436: A frequency shift of one channel to 105.7. Subsequently, this also allowed a later move by WMAX-FM (now sister station WRDG ) on 105.3 from Carrollton east towards Atlanta, also having changed channels from 105.5. WCHK remained under local management for a little over a year afterward, briefly as "North Metro's K-105" then as "Country 105.7", and finally as "Atlanta's Classic Country 105.7", before owner Chuck McClure leased

486-523: A 0.9 rating in the March 2020 Nielsen Audio ratings, which had just been released days prior to the flip. The WBZY call letters would move to 105.7 FM on May 11; in turn, the WRDA calls moved to 105.3 FM. On May 18, 2020, WBZY began simulcasting on WBZW (96.7 FM) once again, but would then drop the simulcast again on November 5, 2021. WBZY's digital subchannel offers one different format: WBZY's main channel

648-399: A 500 kHz frequency separation even when closer frequency spacing is technically permitted. The ITU publishes Protection Ratio graphs, which give the minimum spacing between frequencies based on their relative strengths. Only broadcast stations with large enough geographic separations between their coverage areas can operate on the same or close frequencies. Frequency modulation or FM

810-644: A December 2005 auction. In England, meanwhile, Harrison met sitar maestro Ravi Shankar , who agreed to train him on the instrument. During a tour of the Philippines the month after the Yesterday and Today furore, the Beatles unintentionally snubbed the nation's first lady, Imelda Marcos , who had expected them to attend a breakfast reception at the Presidential Palace . When presented with

972-510: A Spanish-language CHR format as "Z105.7" (the first song played was " Fantasía " by Ozuna ), initially as a simulcast of WBZY (105.3 FM), where the format has been heard since October 2018. WBZY serves areas to the south and west of Atlanta, while WRDA covers the more populous northern and eastern portions of the market, as well as where the majority of the market's Hispanic and Latino population resides. The simulcast would last until May 4, when WBZY adopted WRDG's urban format. Both WBZY and WRDA had

1134-405: A backing band and electric instrumentation , and "dressed in the height of Mod fashion". As a result, Gould continues, the traditional division between folk and rock enthusiasts "nearly evaporated", as the Beatles' fans began to mature in their outlook and Dylan's audience embraced the new, youth-driven pop culture. During the 1964 US tour , the group were confronted with racial segregation in

1296-580: A bass guitar with the proceeds, joined in January 1960. He suggested changing the band's name to Beatals , as a tribute to Buddy Holly and the Crickets . They used this name until May, when they became the Silver Beetles , before undertaking a brief tour of Scotland as the backing group for pop singer and fellow Liverpudlian Johnny Gentle . By early July, they had refashioned themselves as

1458-639: A bright, joyous, original sound, filled with ringing guitars and irresistible melodies." That "ringing guitar" sound was primarily the product of Harrison's 12-string electric Rickenbacker , a prototype given to him by the manufacturer, which made its debut on the record. Touring internationally in June and July, the Beatles staged 37 shows over 27 days in Denmark, the Netherlands, Hong Kong, Australia and New Zealand. In August and September, they returned to

1620-466: A collection of singles. Now we were really beginning to think about albums as a bit of art on their own." Released in December, Rubber Soul was hailed by critics as a major step forward in the maturity and complexity of the band's music. Their thematic reach was beginning to expand as they embraced deeper aspects of romance and philosophy, a development that NEMS executive Peter Brown attributed to

1782-605: A condom in a concrete corridor; the authorities deported them. Lennon returned to Liverpool in early December, while Sutcliffe remained in Hamburg until late February with his German fiancée Astrid Kirchherr , who took the first semi-professional photos of the Beatles. During the next two years, the Beatles were resident for periods in Hamburg, where they used Preludin both recreationally and to maintain their energy through all-night performances. In 1961, during their second Hamburg engagement, Kirchherr cut Sutcliffe's hair in

1944-510: A controversy with Christians in America's conservative Bible Belt region. The Vatican issued a protest, and bans on Beatles records were imposed by Spanish and Dutch stations and South Africa's national broadcasting service . Epstein accused Datebook of having taken Lennon's words out of context. At a press conference, Lennon pointed out, "If I'd said television was more popular than Jesus, I might have got away with it." He claimed that he

2106-544: A copy of the British single "I Want to Hold Your Hand" in mid-December 1963 and began playing it on-air. Taped copies of the song soon circulated among other radio stations throughout the US. This caused an increase in demand, leading Capitol to bring forward the release of "I Want to Hold Your Hand" by three weeks. Issued on 26 December, with the band's previously scheduled debut there just weeks away, "I Want to Hold Your Hand" sold

2268-415: A faster tempo, a studio session in late November yielded that recording, of which Martin accurately predicted, "You've just made your first No. 1". In December 1962, the Beatles concluded their fifth and final Hamburg residency. By 1963, they had agreed that all four band members would contribute vocals to their albums – including Starr, despite his restricted vocal range, to validate his standing in

2430-402: A fax program. The original subcarrier frequency used at KE2XCC was 27.5 kHz. The IF bandwidth was ±5 kHz, as the only goal at the time was to relay AM radio-quality audio. This transmission system used 75 μs audio pre-emphasis like the main monaural audio and subsequently the multiplexed stereo audio. In the late 1950s, several systems to add stereo to FM radio were considered by

2592-413: A few mainstream pop songs, but later dropped them from the playlist. It also phased out the heavy amount of Rhythmic gold product. This move was expected to benefit WWVA (as evidenced on their Facebook page at their website) as it stood to pick up listeners and carry the rhythmic top 40 mantle from WBTS, who exited the rhythmic format after 11 years to become a simulcast of WSB on August 16, 2010. Despite

2754-434: A further progression outside the traditional boundaries of popular music. As the lyrics grew more artful, fans began to study them for deeper meaning. While some of Rubber Soul ' s songs were the product of Lennon and McCartney's collaborative songwriting, the album also included distinct compositions from each, though they continued to share official credit. " In My Life ", of which each later claimed lead authorship,

2916-539: A hybrid regional Mexican and Spanish AC outlet at the latter. On January 11, 2010, the nationally syndicated morning drive-time Elvis Duran and the Morning Show premiered on the station. Duran previously did evenings in Atlanta with sidekick "Hot Henrietta" at Z-93 during the late 1980s. The station briefly aired " Streetz 102.9 " on its HD-2 channel, in order to satisfy a legal fiction so that it could be broadcast on W275BK FM 102.9. A lawsuit regarding

3078-452: A million copies in under four weeks. It became their first single to sell a million copies, and remained the biggest-selling record in the UK until 1978. The success brought increased media exposure, to which the Beatles responded with an irreverent and comical attitude that defied the expectations of pop musicians at the time, inspiring even more interest. The band toured the UK three times in

3240-684: A million copies, becoming a number-one hit in the US by mid-January. In its wake Vee-Jay released Introducing... The Beatles along with Capitol's debut album, Meet the Beatles! , while Swan reactivated production of "She Loves You". On 7 February 1964, the Beatles departed from Heathrow with an estimated 4,000 fans waving and screaming as the aircraft took off. Upon landing at New York's John F. Kennedy Airport , an uproarious crowd estimated at 3,000 greeted them. They gave their first live US television performance two days later on The Ed Sullivan Show , watched by approximately 73 million viewers in over 23 million households, or 34 per cent of

3402-545: A much stronger signal and relocation of their transmitter site from the WTLK-TV 14 (now WPXA-TV ) tower on Bear Mountain (near Lake Arrowhead southwest of Waleska ) south-southeastward toward Atlanta . (This large broadcast tower in Holly Springs is next to Interstate 575 and old Georgia 5 at Rabbit Hill Road, and now only has mobile phone base stations about halfway up on it.) This change also required

3564-406: A new format after Labor Day . A change was also likely due to the station's program director being released days before the change, but on August 30, it was announced that WWVA would retain their rhythmic format, but tweaked its direction towards more hip-hop tracks and less emphasis on dance under its new PD (Rick Vaughn) for both WWVA and WWPW. However, by March 2013, due to the launch of Power,

3726-482: A problem". As a result, six covers from their extensive repertoire were chosen to complete the album. Released in early December, its eight original compositions stood out, demonstrating the growing maturity of the Lennon–McCartney songwriting partnership. In early 1965, following a dinner with Lennon, Harrison and their wives, Harrison's dentist, John Riley, secretly added LSD to their coffee. Lennon described

3888-557: A program feed for AM transmitters of AM/FM stations. SCA subcarriers are typically 67 kHz and 92 kHz. Initially the users of SCA services were private analog audio channels which could be used internally or leased, for example Muzak -type services. There were experiments with quadraphonic sound. If a station does not broadcast in stereo, everything from 23 kHz on up can be used for other services. The guard band around 19 kHz (±4 kHz) must still be maintained, so as not to trigger stereo decoders on receivers. If there

4050-407: A series of articles in which Mann offered detailed analyses of the music, lending it respectability. With the Beatles became the second album in UK chart history to sell a million copies, a figure previously reached only by the 1958 South Pacific soundtrack . When writing the sleeve notes for the album, the band's press officer, Tony Barrow , used the superlative the "fabulous foursome", which

4212-473: A show in Atlanta, the Beatles gave one of the first live performances ever to make use of a foldback system of on-stage monitor speakers. Towards the end of the tour, they met with Elvis Presley , a foundational musical influence on the band, who invited them to his home in Beverly Hills . Presley later said the band was an example of a trend of anti-Americanism and drug abuse. September 1965 saw

4374-597: A simulcast on 96.7 FM for the South Metro in October 2001 (which was dropped in April 2002). On February 3, 2003, at 5 p.m., WMXV began stunting with all- Beatles music. At 12:10 p.m. on February 7, WMXV became WLCL "Cool 105.7" (the first on "Cool" was " You Keep Me Hanging On " by The Supremes ), playing 1960s and 1970s oldies music after Cox Radio dropped its 1950s and 1960s "Fox 97" format from WFOX, which

4536-417: A stereo/mono switch to allow listening in mono when reception conditions are less than ideal, and most car radios are arranged to reduce the separation as the signal-to-noise ratio worsens, eventually going to mono while still indicating a stereo signal is received. As with monaural transmission, it is normal practice to apply pre-emphasis to the left and right channels before encoding and to apply de-emphasis at

4698-511: A stunt featuring the possible return of AC station "The Peach", which was formerly heard on 94.9 FM, and some Christmas music as "Holiday 105.7". At 4 p.m. the same day, the format wheel would officially land on rhythmic AC as "Groove 105.7". (The "Viva" format now airs on the HD2 channel of sister station 105.3 "El Patron".) The new station featured a mix of current and gold-based rhythmic hits targeting ages 25 to 54. Its primary competitors were

4860-437: A succession of drummers, including Pete Best , before inviting Starr to join them in 1962. Manager Brian Epstein moulded them into a professional act, and producer George Martin guided and developed their recordings, greatly expanding their domestic success after they signed with EMI Records and achieved their first hit, " Love Me Do ", in late 1962. As their popularity grew into the intense fan frenzy dubbed " Beatlemania ",

5022-563: A three-motion-picture deal, primarily for the commercial potential of the soundtracks in the US. Directed by Richard Lester , A Hard Day's Night involved the band for six weeks in March–April 1964 as they played themselves in a musical comedy. The film premiered in London and New York in July and August, respectively, and was an international success, with some critics drawing a comparison with

5184-476: A variety of Atlanta stations because of its unique approach: AC WSB-FM , rhythmic WSBB-FM , top-40 WWWQ and WSTR , urbans WVEE and WHTA , and urban ACs WALR-FM and WUMJ . For its kick-off, WWVA's first songs were " Into The Groove " by Madonna , " Shake Your Groove Thing " by Peaches & Herb , " Groove Is In The Heart " by Deee-Lite and " Let's Groove " by Earth, Wind & Fire . Clear Channel, in turn, merged WWVA's format into WBZY's, giving Atlanta

5346-455: A year later to country music WWLG FM 96.7 "The Legend", and later returned to simulcast this station.) On October 19, 2009, at 10 a.m., the station dropped the Spanish format and again began simulcasting WGST AM 640, leading to speculation that it would return to its former news/talk format. At the same time, its website displayed a large question mark. However, the station would shift to

5508-408: Is a form of modulation which conveys information by varying the frequency of a carrier wave ; the older amplitude modulation or AM varies the amplitude of the carrier, with its frequency remaining constant. With FM, frequency deviation from the assigned carrier frequency at any instant is directly proportional to the amplitude of the (audio) input signal, determining the instantaneous frequency of

5670-525: Is added. VHF radio waves usually do not travel far beyond the visual horizon , so reception distances for FM stations are typically limited to 30–40 miles (50–60 km). They can also be blocked by hills and to a lesser extent by buildings. Individuals with more-sensitive receivers or specialized antenna systems, or who are located in areas with more favorable topography, may be able to receive useful FM broadcast signals at considerably greater distances. The knife edge effect can permit reception where there

5832-401: Is as follows: The normal stereo signal can be considered as switching between left and right channels at 38 kHz, appropriately band-limited. The quadraphonic signal can be considered as cycling through LF, LR, RF, RR, at 76 kHz. Early efforts to transmit discrete four-channel quadraphonic music required the use of two FM stations; one transmitting the front audio channels, the other

5994-422: Is authorized for "hybrid" mode operation, wherein both the conventional analog FM carrier and digital sideband subcarriers are transmitted. The output power of an FM broadcasting transmitter is one of the parameters that governs how far a transmission will cover. The other important parameters are the height of the transmitting antenna and the antenna gain . Transmitter powers should be carefully chosen so that

6156-665: Is available online via iHeartRadio . WBZY formerly repeated over the 32.25 digital subchannel of Atlanta television station WANN-CD (29 UHF, 32 PSIP) and previously did so on a number of occasions with sister station WBZW , the most recent lasting until November 5, 2021. The station is also broadcast in HD radio . From its sign-on in 1964 until 1991, the station was country music WCHK-FM on 105.5 MHz in Canton, Georgia , sister station to WCHK AM. In 1993, owner Cherokee Broadcasting received FCC approval to upgrade to class C2 , with

6318-515: Is claimed that no difference can be heard with most newer receivers. At present, the FCC rules do not allow this mode of stereo operation. In 1969, Louis Dorren invented the Quadraplex system of single station, discrete, compatible four-channel FM broadcasting. There are two additional subcarriers in the Quadraplex system, supplementing the single one used in standard stereo FM. The baseband layout

6480-428: Is considered a highlight of the entire Lennon–McCartney catalogue. Harrison called Rubber Soul his "favourite album", and Starr referred to it as "the departure record". McCartney has said, "We'd had our cute period, and now it was time to expand." However, recording engineer Norman Smith later stated that the studio sessions revealed signs of growing conflict within the group – "the clash between John and Paul

6642-508: Is defined by the time constant of a simple RC filter circuit. In most of the world a 50  μs time constant is used. In the Americas and South Korea , 75 μs is used. This applies to both mono and stereo transmissions. For stereo, pre-emphasis is applied to the left and right channels before multiplexing . The use of pre-emphasis becomes a problem because many forms of contemporary music contain more high-frequency energy than

6804-596: Is designed to be capable of use alongside ARI despite using identical subcarrier frequencies. In the United States and Canada , digital radio services are deployed within the FM band rather than using Eureka 147 or the Japanese standard ISDB . This in-band on-channel approach, as do all digital radio techniques, makes use of advanced compressed audio . The proprietary iBiquity system, branded as HD Radio ,

6966-429: Is limited to 30 Hz to 15 kHz to protect a 19 kHz pilot signal. The (L−R) signal, which is also limited to 15 kHz, is amplitude modulated onto a 38 kHz double-sideband suppressed-carrier (DSB-SC) signal, thus occupying 23 kHz to 53 kHz. A 19 kHz ± 2 Hz pilot tone , at exactly half the 38 kHz sub-carrier frequency and with a precise phase relationship to it, as defined by

7128-480: Is mainly the preserve of talk radio, news, sports, religious programming, ethnic (minority language) broadcasting and some types of minority interest music. This shift has transformed AM into the "alternative band" that FM once was. (Some AM stations have begun to simulcast on, or switch to, FM signals to attract younger listeners and aid reception problems in buildings, during thunderstorms, and near high-voltage wires. Some of these stations now emphasize their presence on

7290-671: Is no direct line of sight between broadcaster and receiver. The reception can vary considerably depending on the position. One example is the Učka mountain range, which makes constant reception of Italian signals from Veneto and Marche possible in a good portion of Rijeka , Croatia, despite the distance being over 200 km (125 miles). Other radio propagation effects such as tropospheric ducting and Sporadic E can occasionally allow distant stations to be intermittently received over very large distances (hundreds of miles), but cannot be relied on for commercial broadcast purposes. Good reception across

7452-455: Is now WSRV . At the time, WLCL was the only oldies station in Atlanta; however, the format was not as profitable to companies as it was in Fox 97's prime. On May 2, 2005, the oldies format was ended, and WWVA moved its "Viva" format to the 105.7 frequency. During the flip, "Viva" warned listeners on the old 105.3 frequency to make the change to 105.7 that was played on a format loop. One week later,

7614-496: Is only suitable for text. A few proprietary systems are used for private communications. A variant of RDS is the North American RBDS or "smart radio" system. In Germany the analog ARI system was used prior to RDS to alert motorists that traffic announcements were broadcast (without disturbing other listeners). Plans to use ARI for other European countries led to the development of RDS as a more powerful system. RDS

7776-513: Is open to anyone who does not carry a prohibition and can put up the appropriate licensing and royalty fees. In 2010 around 450 such licences were issued. The Beatles The Beatles were an English rock band formed in Liverpool in 1960. The core lineup of the band comprised John Lennon , Paul McCartney , George Harrison , and Ringo Starr . They are widely regarded as the most influential band of all time and were integral to

7938-508: Is related to the transmitter 's RF power, the antenna gain , and antenna height . Interference from other stations is also a factor in some places. In the U.S, the FCC publishes curves that aid in calculation of this maximum distance as a function of signal strength at the receiving location. Computer modelling is more commonly used for this around the world. Many FM stations, especially those located in severe multipath areas, use extra audio compression /processing to keep essential sound above

8100-630: Is stereo, there will typically be a guard band between the upper limit of the DSBSC stereo signal (53 kHz) and the lower limit of any other subcarrier. Digital data services are also available. A 57 kHz subcarrier ( phase locked to the third harmonic of the stereo pilot tone) is used to carry a low-bandwidth digital Radio Data System signal, providing extra features such as station name, alternative frequency (AF), traffic data for satellite navigation systems and radio text (RT). This narrowband signal runs at only 1,187.5 bits per second , thus

8262-402: Is the sum of twice the maximum deviation and twice the maximum modulating frequency. For a transmission that includes RDS this would be 2 × 75 kHz + 2 × 60 kHz  = 270 kHz . This is also known as the necessary bandwidth . Random noise has a triangular spectral distribution in an FM system, with the effect that noise occurs predominantly at the higher audio frequencies within

8424-754: Is usually a multiple of 100 kHz. In most of South Korea , the Americas , the Philippines , and the Caribbean , only odd multiples are used. Some other countries follow this plan because of the import of vehicles, principally from the United States, with radios that can only tune to these frequencies. In some parts of Europe , Greenland , and Africa , only even multiples are used. In the United Kingdom , both odd and even are used. In Italy , multiples of 50 kHz are used. In most countries

The next day, the band began its fourth tour of Britain within nine months, this one scheduled for six weeks. In mid-November, as Beatlemania intensified, police resorted to using high-pressure water hoses to control the crowd before a concert in Plymouth. On 4 November, they played in front of The Queen Mother and Princess Margaret during

8748-831: The FCC . Included were systems from 14 proponents including Crosby, Halstead, Electrical and Musical Industries, Ltd ( EMI ), Zenith, and General Electric. The individual systems were evaluated for their strengths and weaknesses during field tests in Uniontown, Pennsylvania , using KDKA-FM in Pittsburgh as the originating station. The Crosby system was rejected by the FCC because it was incompatible with existing subsidiary communications authorization (SCA) services which used various subcarrier frequencies including 41 and 67 kHz. Many revenue-starved FM stations used SCAs for "storecasting" and other non-broadcast purposes. The Halstead system

8910-585: The Kaiserkeller in October. When he learned they had been performing at the rival Top Ten Club in breach of their contract, he gave them one month's termination notice, and reported the underage Harrison, who had obtained permission to stay in Hamburg by lying to the German authorities about his age. The authorities arranged for Harrison's deportation in late November. One week later, Koschmider had McCartney and Best arrested for arson after they set fire to

9072-547: The Light Programme , Third Programme and Home Service . These three networks used the sub-band 88.0–94.6 MHz. The sub-band 94.6–97.6 MHz was later used for BBC and local commercial services. However, only when commercial broadcasting was introduced to the UK in 1973 did the use of FM pick up in Britain. With the gradual clearance of other users (notably Public Services such as police, fire and ambulance) and

United Artists released a full soundtrack album for the North American market, combining Beatles songs and Martin's orchestral score; elsewhere, the group's third studio LP, A Hard Day's Night , contained songs from the film on side one and other new recordings on side two. According to Erlewine, the album saw them "truly coming into their own as a band. All of the disparate influences on their first two albums coalesced into

10044-440: The baseband . This can be offset, to a limited extent, by boosting the high frequencies before transmission and reducing them by a corresponding amount in the receiver. Reducing the high audio frequencies in the receiver also reduces the high-frequency noise. These processes of boosting and then reducing certain frequencies are known as pre-emphasis and de-emphasis , respectively. The amount of pre-emphasis and de-emphasis used

On August 29, 2012, sister station WKLS FM ("Project 9-6-1") (now WWPW ) flipped from its long-time rock format to top 40, branded as "Power 96-1". Because WiLD was under the same ownership of Power, and with nearly identical formats, it was likely the two formats would merge, with 105.7/96.7 flipping to

Biographer Jonathan Gould writes that, according to the Nielsen rating service, it was "the largest audience that had ever been recorded for an American television program ". The next morning, the Beatles awoke to a largely negative critical consensus in the US, but a day later at their first US concert, Beatlemania erupted at the Washington Coliseum . Back in New York

During the week of 4 April 1964, the Beatles held twelve positions on the Billboard Hot 100 singles chart, including the top five. Capitol Records' lack of interest throughout 1963 did not go unnoticed, and a competitor, United Artists Records , encouraged its film division to offer the Beatles

11016-709: The Beatles faced a fierce backlash from US religious and social conservatives (as well as the Ku Klux Klan ) over a comment Lennon had made in a March interview with British reporter Maureen Cleave . "Christianity will go", Lennon had said. "It will vanish and shrink. I needn't argue about that; I'm right and I will be proved right ... Jesus was alright but his disciples were thick and ordinary. It's them twisting it that ruins it for me." His comments went virtually unnoticed in England, but when US teenage fan magazine Datebook printed them five months later, it sparked

A 4 September session at EMI yielded a recording of " Love Me Do " featuring Starr on drums, but a dissatisfied Martin hired drummer Andy White for the band's third session a week later, which produced recordings of "Love Me Do", " Please Please Me ", and " P.S. I Love You ". Martin initially selected

11502-631: The Beatles revolutionized many aspects of the music industry and were often publicized as leaders of the era's youth and sociocultural movements. Led by primary songwriters Lennon and McCartney , the Beatles evolved from Lennon's previous group, the Quarrymen , and built their reputation by playing clubs in Liverpool and Hamburg , Germany, over three years from 1960, initially with Stuart Sutcliffe playing bass . The core trio of Lennon, McCartney, and Harrison, together since 1958, went through

11664-665: The FCC announced the reassignment of the FM band to 90 channels from 88–106 MHz (which was soon expanded to 100 channels from 88–108 MHz). This shift, which the AM-broadcaster RCA had pushed for, made all the Armstrong-era FM receivers useless and delayed the expansion of FM. In 1961 WEFM (in the Chicago area) and WGFM (in Schenectady, New York ) were reported as the first stereo stations. By

11826-496: The FCC that the system was compatible with existing two-channel stereo transmission and reception and that it did not interfere with adjacent stations. There were several variations on this system submitted by GE, Zenith, RCA, and Denon for testing and consideration during the National Quadraphonic Radio Committee field trials for the FCC. The original Dorren Quadraplex System outperformed all

11988-520: The FM band.) The medium wave band (known as the AM band because most stations using it employ amplitude modulation) was overcrowded in western Europe, leading to interference problems and, as a result, many MW frequencies are suitable only for speech broadcasting. Belgium , the Netherlands , Denmark and particularly Germany were among the first countries to adopt FM on a widespread scale. Among

12150-979: The FM radio band from 87.5-108.0 MHz to 76.1-108.0 MHz to enable the migration of AM radio stations in Brazilian capitals and large cities. FM broadcasting began in the late 1930s, when it was initiated by a handful of early pioneer experimental stations, including W1XOJ/W43B/WGTR (shut down in 1953) and W1XTG/ WSRS , both transmitting from Paxton, Massachusetts (now listed as Worcester, Massachusetts ); W1XSL/W1XPW/W65H/WDRC-FM/WFMQ/WHCN , Meriden, Connecticut; and W2XMN , KE2XCC , and WFMN , Alpine, New Jersey (owned by Edwin Armstrong himself, closed down upon Armstrong's death in 1954). Also of note were General Electric stations W2XDA Schenectady and W2XOY New Scotland, New York—two experimental FM transmitters on 48.5 MHz—which signed on in 1939. The two began regular programming, as W2XOY, on November 20, 1940. Over

12312-399: The FM transmitter. The terms composite , multiplex and even MPX are used interchangeably to describe this signal. The instantaneous deviation of the transmitter carrier frequency due to the stereo audio and pilot tone (at 10% modulation) is where A and B are the pre-emphasized left and right audio signals and f p {\displaystyle f_{p}} =19 kHz is

12474-649: The Frequency, Kenneth? " and " Radio Song ". One hour later, WWVA/WWLG launched an alternative rock format, branded as "Radio 105.7", with the first song being " It's the End of the World as We Know It (And I Feel Fine) " by R.E.M. (from nearby Athens, Georgia ). This filled the hole left by 99X when it flipped to active rock in September 2012 and adult album alternative WZGC ("92.9 Dave FM") flipping to sports talk

12636-514: The Moondogs, were playing rock and roll whenever they could find a drummer. They also performed as the Rainbows . Paul McCartney later told New Musical Express that they called themselves that "because we all had different coloured shirts and we couldn't afford any others!". Lennon's art school friend Stuart Sutcliffe , who had just sold one of his paintings and was persuaded to purchase

12798-590: The NBC Radio Network, were simultaneously transmitted using the same system of subcarrier modulation as part of a studio-to-transmitter link system. In April 1935, the AM subcarriers were replaced by FM subcarriers, with much improved results. The first FM subcarrier transmissions emanating from Major Armstrong's experimental station KE2XCC at Alpine, New Jersey occurred in 1948. These transmissions consisted of two-channel audio programs, binaural audio programs and

12960-404: The Quarrymen , a reference to their school song "Quarry men old before our birth". Fifteen-year-old Paul McCartney met Lennon on 6 July 1957, and joined as a rhythm guitarist shortly after. In February 1958, McCartney invited his friend George Harrison , then aged fifteen, to watch the band. Harrison auditioned for Lennon, impressing him with his playing, but Lennon initially thought Harrison

13122-567: The Silver Beatles , and by the middle of August simply the Beatles . Allan Williams , the Beatles' unofficial manager, arranged a residency for them in Hamburg . They auditioned and hired drummer Pete Best in mid-August 1960. The band, now a five-piece, departed Liverpool for Hamburg four days later, contracted to club owner Bruno Koschmider for what would be a 3 + 1 ⁄ 2 -month residency. Beatles historian Mark Lewisohn writes: "They pulled into Hamburg at dusk on 17 August,

13284-598: The Starr version of "Love Me Do" for the band's first single, though subsequent re-pressings featured the White version, with Starr on tambourine. Released in early October, "Love Me Do" peaked at number seventeen on the Record Retailer chart. Their television debut came later that month with a live performance on the regional news programme People and Places . After Martin suggested rerecording "Please Please Me" at

13446-411: The US, with a 30-concert tour of 23 cities. Generating intense interest once again, the month-long tour attracted between 10,000 and 20,000 people to each 30-minute performance in cities from San Francisco to New York. In August, journalist Al Aronowitz arranged for the Beatles to meet Bob Dylan . Visiting the band in their New York hotel suite, Dylan introduced them to cannabis . Gould points out

13608-426: The US. A similar situation arose during their May–June tour with Roy Orbison . In late October, the Beatles began a five-day tour of Sweden, their first time abroad since the final Hamburg engagement of December 1962. On their return to the UK on 31 October, several hundred screaming fans greeted them in heavy rain at Heathrow Airport . Around 50 to 100 journalists and photographers, as well as representatives from

13770-532: The United Kingdom to reach number one. The band's third single, " From Me to You ", came out in April and began an almost unbroken string of seventeen British number-one singles, including all but one of the eighteen they released over the next six years. Issued in August, their fourth single, " She Loves You ", achieved the fastest sales of any record in the UK up to that time, selling three-quarters of

13932-415: The airport with news of Sutcliffe's death the previous day from a brain haemorrhage . Epstein began negotiations with record labels for a recording contract. To secure a UK record contract, Epstein negotiated an early end to the band's contract with Polydor, in exchange for more recordings backing Tony Sheridan. After a New Year's Day audition, Decca Records rejected the band , saying, "Guitar groups are on

14094-465: The album Introducing... The Beatles , comprising most of the songs of Parlophone's Please Please Me , but a management shake-up led to the album not being released. After it emerged that the label did not report royalties on their sales, the licence that Vee-Jay had signed with EMI was voided. A new licence was granted to the Swan label for the single "She Loves You". The record received some airplay in

14256-446: The album still sounds fresh, precisely because of its intense origins." Lennon said little thought went into composition at the time; he and McCartney were "just writing songs à la Everly Brothers , à la Buddy Holly, pop songs with no more thought of them than that – to create a sound. And the words were almost irrelevant." Released in March 1963, Please Please Me was the first of eleven consecutive Beatles albums released in

14418-400: The album, recorded between August and October 1964, to continue the format established by A Hard Day's Night which, unlike their first two LPs, contained only original songs. They had nearly exhausted their backlog of songs on the previous album, however, and given the challenges constant international touring posed to their songwriting efforts, Lennon admitted, "Material's becoming a hell of

14580-518: The background noise for listeners, often at the expense of overall perceived sound quality. In such instances, however, this technique is often surprisingly effective in increasing the station's useful range. The first radio station to broadcast in FM in Brazil was Rádio Imprensa, which began broadcasting in Rio de Janeiro in 1955, on the 102.1 MHz frequency, founded by businesswoman Anna Khoury. Due to

14742-674: The band acquired the nickname "the Fab Four". Epstein, Martin or other members of the band's entourage were sometimes informally referred to as a " fifth Beatle ". By early 1964, the Beatles were international stars and had achieved unprecedented levels of critical and commercial success. They became a leading force in Britain's cultural resurgence, ushering in the British Invasion of the United States pop market. They soon made their film debut with A Hard Day's Night (1964). A growing desire to refine their studio efforts, coupled with

14904-447: The band members' "now habitual use of marijuana". Lennon referred to Rubber Soul as "the pot album" and Starr said: "Grass was really influential in a lot of our changes, especially with the writers. And because they were writing different material, we were playing differently." After Help! ' s foray into classical music with flutes and strings, Harrison's introduction of a sitar on " Norwegian Wood (This Bird Has Flown) " marked

15066-409: The band over the next couple of months, and they appointed him as their manager in January 1962. Throughout early and mid-1962, Epstein sought to free the Beatles from their contractual obligations to Bert Kaempfert Productions. He eventually negotiated a one-month early release in exchange for one last recording session in Hamburg. On their return to Germany in April, a distraught Kirchherr met them at

15228-468: The burgeoning youth culture. The group's popularity generated unprecedented interest in British music, and many other UK acts subsequently made their American debuts, successfully touring over the next three years in what was termed the British Invasion . The Beatles' success in the US opened the door for a successive string of British beat groups and pop acts such as the Dave Clark Five ,

15390-508: The challenging nature of their concert tours, led to the band's retirement from live performances in 1966. During this time, they produced albums of greater sophistication, including Rubber Soul (1965), Revolver (1966), and Sgt. Pepper's Lonely Hearts Club Band (1967). They enjoyed further commercial success with The Beatles (also known as "the White Album", 1968) and Abbey Road (1969). The success of these records heralded

15552-452: The commercialised popular culture of television, radio, pop records, fan magazines, and teen fashion. To many of Dylan's followers in the folk music scene, the Beatles were seen as idolaters, not idealists." Within six months of the meeting, according to Gould, "Lennon would be making records on which he openly imitated Dylan's nasal drone, brittle strum, and introspective vocal persona"; and six months after that, Dylan began performing with

15714-599: The country at the time. When informed that the venue for their 11 September concert, the Gator Bowl in Jacksonville, Florida , was segregated, the Beatles said they would refuse to perform unless the audience was integrated. Lennon stated: "We never play to segregated audiences and we aren't going to start now ... I'd sooner lose our appearance money." City officials relented and agreed to allow an integrated show. The group also cancelled their reservations at

15876-431: The country is one of the main advantages over DAB/+ radio . This is still less than the range of AM radio waves, which because of their lower frequencies can travel as ground waves or reflect off the ionosphere , so AM radio stations can be received at hundreds (sometimes thousands) of miles. This is a property of the carrier wave's typical frequency (and power), not its mode of modulation. The range of FM transmission

16038-405: The customary group photograph, its Aubrey Beardsley -inspired cover – designed by Klaus Voormann , a friend of the band since their Hamburg days – was a monochrome collage and line drawing caricature of the group. The album was preceded by the single " Paperback Writer ", backed by " Rain ". Short promotional films were made for both songs; described by cultural historian Saul Austerlitz as "among

16200-427: The development of 1960s counterculture and the recognition of popular music as an art form. Rooted in skiffle , beat , and 1950s rock 'n' roll , their sound incorporated elements of classical music and traditional pop in innovative ways. The band also explored music styles ranging from folk and Indian music to psychedelia and hard rock . As pioneers in recording , songwriting, and artistic presentation,

16362-413: The experience: "It was just terrifying, but it was fantastic. I was pretty stunned for a month or two." He and Harrison subsequently became regular users of the drug, joined by Starr on at least one occasion. Harrison's use of psychedelic drugs encouraged his path to meditation and Hinduism. He commented: "For me, it was like a flash. The first time I had acid , it just opened up something in my head that

16524-567: The extension of the FM band to 108.0 MHz between 1980 and 1995, FM expanded rapidly throughout the British Isles and effectively took over from LW and MW as the delivery platform of choice for fixed and portable domestic and vehicle-based receivers. In addition, Ofcom (previously the Radio Authority) in the UK issues on demand Restricted Service Licences on FM and also on AM (MW) for short-term local-coverage broadcasting which

16686-517: The first Beatle to discuss LSD publicly, declaring in a magazine interview that "it opened my eyes" and "made me a better, more honest, more tolerant member of society". Controversy erupted in June 1965 when Queen Elizabeth II appointed all four Beatles Members of the Order of the British Empire (MBE) after Prime Minister Harold Wilson nominated them for the award. In protest – the honour

16848-564: The first half of the year: a four-week tour that began in February, the Beatles' first nationwide, preceded three-week tours in March and May–June. As their popularity spread, a frenzied adulation of the group took hold. On 13 October, the Beatles starred on Sunday Night at the London Palladium , the UK's top variety show. Their performance was televised live and watched by 15 million viewers. One national paper's headlines in

17010-402: The following day, the Beatles met with another strong reception during two shows at Carnegie Hall . The band flew to Florida, where they appeared on The Ed Sullivan Show a second time, again before 70 million viewers, before returning to the UK on 22 February. The Beatles' first visit to the US took place when the nation was still mourning the assassination of President John F. Kennedy

17172-412: The following days coined the term " Beatlemania " to describe the riotous enthusiasm by screaming fans who greeted the band – and it stuck. Although not billed as tour leaders, the Beatles overshadowed American acts Tommy Roe and Chris Montez during the February engagements and assumed top billing "by audience demand", something no British act had previously accomplished while touring with artists from

17334-641: The following month. The two stations' broadcast callsigns were changed to WRDA and WRDG, respectively, on April 11, and the "Wild" format moved to WWPW FM 96.1 HD2, replacing the "Project 9-6-1" format that was eliminated from analog and HD1 by Wild's near-clone "Power 96-1". On November 11, 2016, WRDG dropped its simulcast of WRDA and flipped to urban; however, WRDA retained the alternative format. On December 5, 2017, WRDA rebranded as "Alt 105-7", to align itself with other iHeartMedia-owned alternative outlets. On April 20, 2020, at Midnight, after playing "Novocaine" by The Unlikely Candidates , WRDA flipped back to

17496-481: The formula below, is also generated. The pilot is transmitted at 8–10% of overall modulation level and used by the receiver to identify a stereo transmission and to regenerate the 38 kHz sub-carrier with the correct phase. The composite stereo multiplex signal contains the Main Channel (L+R), the pilot tone, and the (L−R) difference signal. This composite signal, along with any other sub-carriers, modulates

17658-482: The frequency of the pilot tone. Slight variations in the peak deviation may occur in the presence of other subcarriers or because of local regulations. Another way to look at the resulting signal is that it alternates between left and right at 38 kHz, with the phase determined by the 19 kHz pilot signal. Most stereo encoders use this switching technique to generate the 38 kHz subcarrier, but practical encoder designs need to incorporate circuitry to deal with

17820-429: The grinning Beatles dressed in butcher's overalls, accompanied by raw meat and mutilated plastic baby dolls. According to Beatles biographer Bill Harry , it has been incorrectly suggested that this was meant as a satirical response to the way Capitol had "butchered" the US versions of the band's albums. Thousands of copies of the LP had a new cover pasted over the original; an unpeeled "first-state" copy fetched $ 10,500 at

17982-404: The group's break-up in 1970, all principal former members enjoyed success as solo artists, and some partial reunions occurred. Lennon was murdered in 1980, and Harrison died of lung cancer in 2001. McCartney and Starr remain musically active. The Beatles are the best-selling music act of all time , with estimated sales of 600 million units worldwide. They are the most successful act in

18144-524: The group. Lennon and McCartney had established a songwriting partnership , and as the band's success grew, their dominant collaboration limited Harrison's opportunities as a lead vocalist . Epstein, to maximise the Beatles' commercial potential, encouraged them to adopt a professional approach to performing. Lennon recalled him saying, "Look, if you really want to get in these bigger places, you're going to have to change – stop eating on stage, stop swearing, stop smoking ...". On 11 February 1963,

18306-513: The high import costs of FM radio receivers, transmissions were carried out in circuit closed to businesses and stores, which played ambient music offered by radio. Until 1976, Rádio Imprensa was the only station operating in FM in Brazil. From the second half of the 1970s onwards, FM radio stations began to become popular in Brazil, causing AM radio to gradually lose popularity. In 2021, the Brazilian Ministry of Communications expanded

18468-678: The history of the US Billboard charts , holding the record for most number-one albums on the UK Albums Chart (15), most number-one hits on the US Billboard Hot 100 chart (20), and most singles sold in the UK (21.9 million). The band received many accolades , including seven Grammy Awards , four Brit Awards , an Academy Award (for Best Original Song Score for the 1970 documentary film Let It Be ), and fifteen Ivor Novello Awards . They were inducted into

18630-614: The invitation, Epstein politely declined on the band members' behalf, as it had never been his policy to accept such official invitations. They soon found that the Marcos regime was unaccustomed to taking no for an answer. The resulting riots endangered the group and they escaped the country with difficulty. Immediately afterwards, the band members visited India for the first time. We're more popular than Jesus now; I don't know which will go first – rock 'n' roll or Christianity. – John Lennon, 1966 Almost as soon as they returned home,

18792-401: The last covers the band would include on an album until Let It Be 's brief rendition of the traditional Liverpool folk song " Maggie Mae ". The band expanded their use of vocal overdubs on Help! and incorporated classical instruments into some arrangements, including a string quartet on the pop ballad " Yesterday ". Composed and sung by McCartney – none of the other Beatles perform on

18954-524: The late 1960s, FM had been adopted for broadcast of stereo "A.O.R.—' Album Oriented Rock ' Format", but it was not until 1978 that listenership to FM stations exceeded that of AM stations in North America. In most of the 70s FM was seen as highbrow radio associated with educational programming and classical music, which changed during the 1980s and 1990s when Top 40 music stations and later even country music stations largely abandoned AM for FM. Today AM

19116-446: The late 1970s, Dolby FM was similar to Dolby B but used a modified 25 μs pre-emphasis time constant and a frequency selective companding arrangement to reduce noise. The pre-emphasis change compensates for the excess treble response that otherwise would make listening difficult for those without Dolby decoders. A similar system named High Com FM was tested in Germany between July 1979 and December 1981 by IRT . It

19278-519: The launch of an American Saturday-morning cartoon series, The Beatles , that echoed A Hard Day's Night 's slapstick antics over its two-year original run. The series was the first weekly television series to feature animated versions of real, living people. In mid-October, the Beatles entered the recording studio; for the first time when making an album, they had an extended period without other major commitments. Until this time, according to George Martin, "we had been making albums rather like

19440-465: The left (L) and right (R) channels are algebraically encoded into sum (L+R) and difference (L−R) signals. A mono receiver will use just the L+R signal so the listener will hear both channels through the single loudspeaker. A stereo receiver will add the difference signal to the sum signal to recover the left channel, and subtract the difference signal from the sum to recover the right channel. The (L+R) signal

19602-480: The maximum permitted carrier deviation is invariably ±75 kHz, although a little higher is permitted in the United States when SCA systems are used. For a monophonic broadcast, again the most common permitted maximum deviation is ±75 kHz. However, some countries specify a lower value for monophonic broadcasts, such as ±50 kHz. The bandwidth of an FM transmission is given by the Carson bandwidth rule which

19764-427: The maximum permitted frequency error of the unmodulated carrier is specified, which typically should be within 2 kHz of the assigned frequency. There are other unusual and obsolete FM broadcasting standards in some countries, with non-standard spacings of 1, 10, 30, 74, 500, and 300 kHz. To minimise inter-channel interference, stations operating from the same or nearby transmitter sites tend to keep to at least

19926-408: The media widely adopted as "the Fab Four". EMI's American subsidiary, Capitol Records , hindered the Beatles' releases in the United States for more than a year by initially declining to issue their music, including their first three singles. Concurrent negotiations with the independent US label Vee-Jay led to the release of some, but not all, of the songs in 1963. Vee-Jay finished preparation for

20088-409: The moderate success of "Love Me Do", the single "Please Please Me" was released in January 1963, two months ahead of the album. It reached number one on every UK chart except Record Retailer , where it peaked at number two. Recalling how the Beatles "rushed to deliver a debut album, bashing out Please Please Me in a day", AllMusic critic Stephen Thomas Erlewine wrote: "Decades after its release,

20250-496: The monotony of numerous appearances at the same clubs night after night. In November 1961, during one of the group's frequent performances at the Cavern Club , they encountered Brian Epstein , a local record-store owner and music columnist. He later recalled: "I immediately liked what I heard. They were fresh, and they were honest, and they had what I thought was a sort of presence ... [a] star quality." Epstein courted

20412-413: The move of Elvis Duran and the Morning Show to WWPW, and a lack of promotion, ratings had tumbled from a mid-3 share to a 1.8 share, among the lowest-rated commercial music radio stations in the area. Therefore, on March 28, 2013, at 11:00 a.m., with little warning, after playing " Rosa Parks " by Atlanta hip hop group OutKast , WWVA/WWLG went into a stunt loop consisting of R.E.M. 's " What's

20574-445: The musical and cultural significance of this meeting, before which the musicians' respective fanbases were "perceived as inhabiting two separate subcultural worlds": Dylan's audience of "college kids with artistic or intellectual leanings, a dawning political and social idealism, and a mildly bohemian style " contrasted with their fans, "veritable ' teenyboppers ' – kids in high school or grade school whose lives were totally wrapped up in

20736-474: The musical styles which prevailed at the birth of FM broadcasting. Pre-emphasizing these high-frequency sounds would cause excessive deviation of the FM carrier . Modulation control (limiter) devices are used to prevent this. Systems more modern than FM broadcasting tend to use either programme-dependent variable pre-emphasis; e.g., dbx in the BTSC TV sound system, or none at all. Pre-emphasis and de-emphasis

20898-540: The next few years this station operated under the call signs W57A, W87A and WGFM, and moved to 99.5 MHz when the FM band was relocated to the 88–108 MHz portion of the radio spectrum. General Electric sold the station in the 1980s. Today this station is WRVE . Other pioneers included W2XQR/W59NY/WQXQ/WQXR-FM , New York; W47NV/WSM-FM Nashville, Tennessee (signed off in 1951); W1XER/W39B/WMNE , with studios in Boston and later Portland, Maine, but whose transmitter

21060-570: The others and was chosen as the national standard for Quadraphonic FM broadcasting in the United States. The first commercial FM station to broadcast quadraphonic program content was WIQB (now called WWWW-FM ) in Ann Arbor / Saline, Michigan under the guidance of Chief Engineer Brian Jeffrey Brown. Various attempts to add analog noise reduction to FM broadcasting were carried out in the 1970s and 1980s: A commercially unsuccessful noise reduction system used with FM radio in some countries during

21222-620: The owners of that broadcast translator quickly ensued, and W275BK is now assigned to WAMJ . Since the end of March 2010, the station is now also simulcast on WANN-CD , a low-power digital TV station on physical ( RF ) TV channel 29 in Atlanta. The main channel was heard on virtual channel 32.106, with Pride Radio (WWVA's HD2 digital subchannel ) formerly on 32.105. Clear Channel's other Atlanta stations are also heard via DTV radio on WANN. In May 2010, WWVA's music and playlist direction shifted to rhythmic top 40 by adding more current rhythmic pop/R&B/dance tracks. They also added

21384-418: The previous November. Commentators often suggest that for many, particularly the young, the Beatles' performances reignited the sense of excitement and possibility that momentarily faded in the wake of the assassination, and helped pave the way for the revolutionary social changes to come later in the decade. Their hairstyle, unusually long for the era and mocked by many adults, became an emblem of rebellion to

21546-507: The rear channels. A breakthrough came in 1970 when KIOI ( K-101 ) in San Francisco successfully transmitted true quadraphonic sound from a single FM station using the Quadraplex system under Special Temporary Authority from the FCC . Following this experiment, a long-term test period was proposed that would permit one FM station in each of the top 25 U.S. radio markets to transmit in Quadraplex. The test results hopefully would prove to

21708-511: The reasons for this were: Public service broadcasters in Ireland and Australia were far slower at adopting FM radio than those in either North America or continental Europe . Hans Idzerda operated a broadcasting station, PCGG , at The Hague from 1919 to 1924, which employed narrow-band FM transmissions. In the United Kingdom the BBC conducted tests during the 1940s, then began FM broadcasting in 1955, with three national networks:

21870-478: The receiver after decoding. In the U.S. around 2010, using single-sideband modulation for the stereo subcarrier was proposed. It was theorized to be more spectrum-efficient and to produce a 4 dB s/n improvement at the receiver, and it was claimed that multipath distortion would be reduced as well. A handful of radio stations around the country broadcast stereo in this way, under FCC experimental authority. It may not be compatible with very old receivers, but it

22032-613: The recording  – "Yesterday" has inspired the most cover versions of any song ever written. With Help! , the Beatles became the first rock group to be nominated for a Grammy Award for Album of the Year . The group's third US tour opened with a performance before a world-record crowd of 55,600 at New York's Shea Stadium on 15 August – "perhaps the most famous of all Beatles' concerts", in Lewisohn's description. A further nine successful concerts followed in other American cities. At

22194-570: The required area is covered without causing interference to other stations further away. Practical transmitter powers range from a few milliwatts to 80 kW. As transmitter powers increase above a few kilowatts, the operating costs become high and only viable for large stations. The efficiency of larger transmitters is now better than 70% (AC power in to RF power out) for FM-only transmission. This compares to 50% before high efficiency switch-mode power supplies and LDMOS amplifiers were used. Efficiency drops dramatically if any digital HD Radio service

22356-555: The sessions, the Beatles were signed to Polydor for one year. Credited to "Tony Sheridan & the Beat Brothers", the single " My Bonnie ", recorded in June 1961 and released four months later, reached number 32 on the Musikmarkt chart. After the Beatles completed their second Hamburg residency, they enjoyed increasing popularity in Liverpool with the growing Merseybeat movement. However, they were growing tired of

22518-585: The station and license outright from McClure, and still holds Canton as its city of license . A new WCHK-FM, located at 100.1 and also owned by McClure, was sold and changed to WNSY FM ( oldies "Sunny 100") in 1999, later becoming the market 's third hispanic FM station, but covering more toward northwest Georgia . On September 8, 2000, 105.7 broke away from the WGST simulcast, and became Rock AC / classic rock "Mix 105.7" (WMXV), but did not stay that way for long due to lagging Arbitron ratings , despite adding

22680-537: The station officially became WWVA-FM itself, swapping the WLCL callsign over to 105.3, where "The Buzz" format from 96.7 was put. Strangely, that left the hard modern rock of "The Buzz" with the WLCL call letters instead of its own WBZY-FM, which was unused for about two weeks. ("The Buzz" later merged into "96 Rock", becoming "Project 9-6-1", but remaining as WKLS .) "Viva 105.7" began simulcasting on 96.7 FM (formerly "The Buzz") on May 17, 2005, and that station's callsign

22842-507: The station to iHeartMedia (which also owns 105.3), then known as Clear Channel Communications. Under Clear Channel management , the station became WGST-FM and simulcast news / talk WGST , beginning October 1, 1993. In the mid-1990s, it again relocated its transmitter site southward, this time to the Sweat Mountain antenna farm in northeastern Cobb County (where several other stations are). In 2004, Clear Channel purchased

23004-473: The sudden shift to rhythmic top 40 and primary signal coverage into Atlanta, there was some criticism over whether WWVA could actually replace WBTS, or fill the void for that matter, in terms of music, personalities, area promotion, and signal presence. In efforts to fill in a signal shortcoming in southern portions of the market, the station re-added WWLG FM 96.7 as a simulcast on September 6, 2010. It also changed its positioner to "Atlanta's Party Station", which

23166-462: The switching harmonics. Converting the multiplex signal back into left and right audio signals is performed by a decoder, built into stereo receivers. Again, the decoder can use a switching technique to recover the left and right channels. In addition, for a given RF level at the receiver, the signal-to-noise ratio and multipath distortion for the stereo signal will be worse than for the mono receiver. For this reason many stereo FM receivers include

23328-484: The time when the red-light area comes to life ... flashing neon lights screamed out the various entertainment on offer, while scantily clad women sat unabashed in shop windows waiting for business opportunities." Koschmider had converted a couple of strip clubs in the district into music venues, and he initially placed the Beatles at the Indra Club . After closing Indra due to noise complaints, he moved them to

23490-529: The top spot for 21 weeks with a chart life of 40 weeks. Erlewine described the LP as "a sequel of the highest order – one that betters the original". In a reversal of then standard practice, EMI released the album ahead of the impending single " I Want to Hold Your Hand ", with the song excluded to maximise the single's sales. The album caught the attention of music critic William Mann of The Times , who suggested that Lennon and McCartney were "the outstanding English composers of 1963". The newspaper published

23652-465: The transmitted signal. Because transmitted FM signals use significantly more bandwidth than AM signals, this form of modulation is commonly used with the higher ( VHF or UHF ) frequencies used by TV , the FM broadcast band , and land mobile radio systems . The maximum frequency deviation of the carrier is usually specified and regulated by the licensing authorities in each country. For a stereo broadcast,

23814-433: The way out, Mr. Epstein". However, three months later, producer George Martin signed the Beatles to EMI 's Parlophone label. Martin's first recording session with the Beatles took place at EMI Recording Studios (later Abbey Road Studios) in London on 6 June 1962. He immediately complained to Epstein about Best's drumming and suggested they use a session drummer in his place. Already contemplating Best's dismissal,

23976-460: The whites-only Hotel George Washington in Jacksonville. For their subsequent US tours in 1965 and 1966, the Beatles included clauses in contracts stipulating that shows be integrated. According to Gould, the Beatles' fourth studio LP, Beatles for Sale , evidenced a growing conflict between the commercial pressures of their global success and their creative ambitions. They had intended

24138-538: Was also heard on DTV radio via digital low-power TV station WANN-CD 29, on virtual channel 32.23, with the former WiLD format on 32.25. [REDACTED] [REDACTED] FM broadcasting Throughout the world, the FM broadcast band falls within the VHF part of the radio spectrum . Usually 87.5 to 108.0 MHz is used, or some portion of it, with few exceptions: The frequency of an FM broadcast station (more strictly its assigned nominal center frequency)

24300-439: Was at that time primarily bestowed upon military veterans and civic leaders – some conservative MBE recipients returned their insignia. In July, the Beatles' second film, Help! , was released, again directed by Lester. Described as "mainly a relentless spoof of Bond ", it inspired a mixed response among both reviewers and the band. McCartney said: " Help! was great but it wasn't our film – we were sort of guest stars. It

24462-616: Was atop the highest mountain in the northeast United States, Mount Washington , New Hampshire (shut down in 1948); and W9XAO/W55M/WTMJ-FM Milwaukee, Wisconsin (went off air in 1950). A commercial FM broadcasting band was formally established in the United States as of January 1, 1941, with the first fifteen construction permits announced on October 31, 1940. These stations primarily simulcast their AM sister stations, in addition to broadcasting lush orchestral music for stores and offices, classical music to an upmarket listenership in urban areas, and educational programming. On June 27, 1945

24624-530: Was based on the Telefunken High ;Com broadband compander system, but was never introduced commercially in FM broadcasting. Yet another system was the CX -based noise reduction system FMX implemented in some radio broadcasting stations in the United States in the 1980s. FM broadcasting has included subsidiary communications authorization (SCA) services capability since its inception, as it

24786-514: Was becoming obvious", he wrote, and "as far as Paul was concerned, George could do no right". Capitol Records, from December 1963 when it began issuing Beatles recordings for the US market, exercised complete control over format, compiling distinct US albums from the band's recordings and issuing songs of their choosing as singles. In June 1966, the Capitol LP Yesterday and Today caused an uproar with its cover, which portrayed

24948-519: Was changed to WVWA (an anagram of WWVA, with the two middle letters transposed ). Because 105.7 is north of Atlanta, 96.7 gave some coverage to the south. Its far-northeastern simulcast on WHEL (105.1 FM) in Helen, Georgia was sold in 2005, and has since changed formats to hot AC . On December 20, 2006, WVWA flipped formats to 94.9 's former adult contemporary format as "96.7 Lite FM" and took its WLTM callsign as well. (This station would flip about

25110-512: Was fun, but basically, as an idea for a film, it was a bit wrong." The soundtrack was dominated by Lennon, who wrote and sang lead on most of its songs, including the two singles: " Help! " and " Ticket to Ride ". The Help! album, the group's fifth studio LP, mirrored A Hard Day's Night by featuring soundtrack songs on side one and additional songs from the same sessions on side two. The LP contained all original material save for two covers, " Act Naturally " and " Dizzy Miss Lizzy "; they were

25272-457: Was inside of me, and I realised a lot of things. I didn't learn them because I already knew them, but that happened to be the key that opened the door to reveal them. From the moment I had that, I wanted to have it all the time – these thoughts about the yogis and the Himalayas, and Ravi 's music." McCartney was initially reluctant to try it, but eventually did so in late 1966. He became

25434-424: Was last used at WWLG's predecessor WLDA when it was "Wild 96.7". Another move came from the hiring of former WBTS and WHTA DJ-mixer Mami Chula to The Groove's lineup. On November 14, 2010, the station changed its name to "WiLD 105.7 & 96.7", retaining the "Atlanta's Party Station" slogan. (The first song on "WiLD" was " We R Who We R " by Ke$ ha .) WWVA saw an increase in terms of listeners and ratings, mostly among

25596-526: Was referring to how other people viewed their success, but at the prompting of reporters, he concluded: "If you want me to apologise, if that will make you happy, then okay, I'm sorry." Released in August 1966, a week before the Beatles' final tour, Revolver marked another artistic step forward for the group. The album featured sophisticated songwriting, studio experimentation, and a greatly expanded repertoire of musical styles, ranging from innovative classical string arrangements to psychedelia . Abandoning

25758-457: Was rejected due to lack of high frequency stereo separation and reduction in the main channel signal-to-noise ratio. The GE and Zenith systems, so similar that they were considered theoretically identical, were formally approved by the FCC in April 1961 as the standard stereo FM broadcasting method in the United States and later adopted by most other countries. It is important that stereo broadcasts be compatible with mono receivers. For this reason,

25920-565: Was seen as another service which licensees could use to create additional income. Use of SCAs was particularly popular in the US, but much less so elsewhere. Uses for such subcarriers include radio reading services for the blind , which became common and remain so, private data transmission services (for example sending stock market information to stockbrokers or stolen credit card number denial lists to stores, ) subscription commercial-free background music services for shops, paging ("beeper") services, alternative-language programming, and providing

26082-504: Was too young. After a month's persistence, during a second meeting (arranged by McCartney), Harrison performed the lead guitar part of the instrumental song " Raunchy " on the upper deck of a Liverpool bus, and they enlisted him as lead guitarist . By January 1959, Lennon's Quarry Bank friends had left the group, and he began his studies at the Liverpool College of Art . The three guitarists, billing themselves as Johnny and

26244-446: Was used in the earliest days of FM broadcasting. According to a BBC report from 1946, 100 μs was originally considered in the US, but 75 μs subsequently adopted. Long before FM stereo transmission was considered, FM multiplexing of other types of audio-level information was experimented with. Edwin Armstrong, who invented FM, was the first to experiment with multiplexing, at his experimental 41 MHz station W2XDG located on
