54-633: WQDR (570 kHz ; "Rock FM") is a classic rock AM radio station, licensed to Raleigh, North Carolina , which serves the Research Triangle region. WQDR's studios are located in Raleigh, and its transmitter is co-located at the WPTF transmitter site in Cary . Its programming is carried over the station's translator on 98.3 FM (W252EL) in Cary, North Carolina , as well as WQDR-FM-HD3, which in turn

108-551: A local marketing agreement with Capitol Broadcasting Company (CBC), which allowed the Raleigh-based company control over WDNC's sales, marketing and programming with an option to buy. Capitol, already in the process of moving their minor league baseball team, the Durham Bulls , into the new Durham Bulls Athletic Park being built by the city, announced plans to move WDNC into the ballpark upon its completion in 1995. In

162-552: A more detailed treatment of this and the above frequency ranges, see Electromagnetic spectrum . Gravitational waves are also described in Hertz. Current observations are conducted in the 30–7000 Hz range by laser interferometers like LIGO , and the nanohertz (1–1000 nHz) range by pulsar timing arrays . Future space-based detectors are planned to fill in the gap, with LISA operating from 0.1–10 mHz (with some sensitivity from 10 μHz to 100 mHz), and DECIGO in

216-502: A temporary "Interim Operation" authorization to take over the station, with most programming unchanged. In 1981 the FCC conducted competitive hearing between three applicants to acquire the station, and selected Special Markets Media, Inc., owned by Prentice J. Monroe (75%) and her husband Henry (25%), who continued its well-known R&B format. In the early 1990s, "Let's Talk", hosted by Frank Roberts, aired five nights each week and dealt with

270-427: Is 1/time (T ). Expressed in base SI units, the unit is the reciprocal second (1/s). In English, "hertz" is also used as the plural form. As an SI unit, Hz can be prefixed ; commonly used multiples are kHz (kilohertz, 10  Hz ), MHz (megahertz, 10  Hz ), GHz (gigahertz, 10  Hz ) and THz (terahertz, 10  Hz ). One hertz (i.e. one per second) simply means "one periodic event occurs per second" (where

324-494: Is also used to describe the clock speeds at which computers and other electronics are driven. The units are sometimes also used as a representation of the energy of a photon , via the Planck relation E  =  hν , where E is the photon's energy, ν is its frequency, and h is the Planck constant . The hertz is defined as one per second for periodic events. The International Committee for Weights and Measures defined

378-581: Is now WDNC was first licensed June 19, 1928, as WRBT (1370 AM) in Wilmington, North Carolina , which changed its call sign to WRAM in 1931. Durham's first radio station went on the air in February 1934, when then-Mayor W.F. Carr and several investors saw the need for a radio station in what was then the state's third-largest city. They bought WRAM and moved its license and equipment to studios in Durham atop

432-616: Is relayed by translators at 93.3 FM (W227CZ) in Durham, North Carolina , 93.5 FM (W228CV) in Chapel Hill, North Carolina and 100.3 FM (W262CZ) in Raleigh, North Carolina. The station was first licensed in 1954 as WMSN, with 500 watts, daytime-only, on 570 kHz. The station manager was B. H. Ingle, Sr., pastor of the First Missionary Church and owner of B. H. Ingle & Sons Roofing and Heating Company. Programming

486-503: Is used only in the case of periodic events. It is named after Heinrich Rudolf Hertz (1857–1894), the first person to provide conclusive proof of the existence of electromagnetic waves . For high frequencies, the unit is commonly expressed in multiples : kilohertz (kHz), megahertz (MHz), gigahertz (GHz), terahertz (THz). Some of the unit's most common uses are in the description of periodic waveforms and musical tones , particularly those used in radio - and audio-related applications. It

540-452: Is usually measured in kilohertz (kHz), megahertz (MHz), or gigahertz (GHz). with the latter known as microwaves . Light is electromagnetic radiation that is even higher in frequency, and has frequencies in the range of tens of terahertz (THz, infrared ) to a few petahertz (PHz, ultraviolet ), with the visible spectrum being 400–790 THz. Electromagnetic radiation with frequencies in the low terahertz range (intermediate between those of

594-582: The LMA from Capitol, replacing the news-centered schedule with more syndicated talk shows and paid programming until it bought the WDNC license from the Herald-Sun in 2000. In November 2002, WDNC began a simulcast with Raleigh station WDNZ (now WQDR ), 570 AM. That arrangement lasted until November 1, 2005, when WDNC entered into yet another LMA, this time with McClatchey Broadcasting , then-owner of WRBZ "850

648-449: The 0.1–10 Hz range. In computers, most central processing units (CPU) are labeled in terms of their clock rate expressed in megahertz ( MHz ) or gigahertz ( GHz ). This specification refers to the frequency of the CPU's master clock signal . This signal is nominally a square wave , which is an electrical voltage that switches between low and high logic levels at regular intervals. As

702-475: The 1950s that were no longer played on most oldies formats. The music segments were hosted by longtime Triangle area radio personalities Pat Patterson and Maury O'Dell. In May 2010, the station changed its call letters to WQDR and its format to classic country to go along with sister station WQDR-FM , which plays contemporary and hit country music. WQDR went off the air beginning April 16, 2011, when its transmitter off South Saunders Street near downtown Raleigh

756-468: The 1970s. In some usage, the "per second" was omitted, so that "megacycles" (Mc) was used as an abbreviation of "megacycles per second" (that is, megahertz (MHz)). Sound is a traveling longitudinal wave , which is an oscillation of pressure . Humans perceive the frequency of a sound as its pitch . Each musical note corresponds to a particular frequency. An infant's ear is able to perceive frequencies ranging from 20 Hz to 20 000  Hz ;

810-509: The Buzz", a more locally oriented sports talk station. The station flipped to sports talk as "620 The Bull". From July 2006 to June 2007, WDNC was home to an afternoon talk show featuring former ECU football head coach Steve Logan , before moving on to take the offensive coordinator position at Boston College . Late in 2008, Don Imus returned to the Triangle for the first time since

Ray "Dr. Jocko" Henderson, who later became well known in Detroit, was popular with both black and white listeners in the 1960s. He is credited with helping Raleigh get through difficult times during integration of

918-446: The Triangle affiliate for Premiere Radio Networks' 24/7 Comedy radio network, until it was discontinued on August 3, 2014. At that point WFNL switched to the "Today's Comedy" network feed. Beginning with the 2015 season, WFNL broadcast East Carolina University Pirates football games and the weekly coaches show. The station inherited this package from sister station WPTK , which had recently changed formats. In May 2017, WFNL dropped

972-482: The U.S. Supreme Court upheld the license revocation. At this point station owner Wallace L. Hankin was given until January 27, 1980 to find a charitable or non-profit organization to assume station operations, but was unable to meet this deadline, and the station suspended broadcasting. However, a short time later the Roman Catholic Diocese of Raleigh formed Faith Communications, Inc., which was granted

1026-555: The WLLE of the past. Plans call for community affairs programming. KHz The hertz (symbol: Hz ) is the unit of frequency in the International System of Units (SI), often described as being equivalent to one event (or cycle ) per second . The hertz is an SI derived unit whose formal expression in terms of SI base units is s , meaning that one hertz is one per second or the reciprocal of one second . It

1080-740: The Washington Duke Hotel downtown at the corner of Corcoran and Chapel Hill Streets (later known as the Carolina and the Jack Tar Hotel; the structure was imploded in 1975). The newly relocated station signed on with 100 watts at 1500 AM as CBS affiliate WDNC. In 1936, WDNC was purchased by the Herald-Sun Newspapers , publishers of the Durham Morning Herald and The Durham Sun . At this time,

1134-513: The air, so WDNC aired news for the city's residents. In the late 1970s, Buddy Poole, a former employee of WTIK, hosted the "Country Lovin'" morning show and worked in sales. WDNC remained a CBS affiliate and the home of big band and popular standards until 1991, when their focus shifted towards more talk-based programming. In 1992, WDNC and its FM sister station, by now known as WDCG "G-105", relocated to Park Forty Plaza, just off Interstate 40 along NC Highway 55 in southeastern Durham, as

The range of ultrasound , infrasound and other physical vibrations such as molecular and atomic vibrations extends from a few femtohertz into the terahertz range and beyond. Electromagnetic radiation is often described by its frequency—the number of oscillations of the perpendicular electric and magnetic fields per second—expressed in hertz. Radio frequency radiation

1242-470: The banner "Durham Broadcasting Enterprises" and signed on WTVD , channel 11 on September 2, 1954. In 1957, Durham Broadcasting sold WTVD to Albany, New York -based Capital Cities Broadcasting in 1957 (the same Capital Cities which bought the ABC TV network in the mid-1980s). In October 1954, Raleigh, North Carolina had significant damage from Hurricane Hazel . All of the city's radio stations were off

1296-529: The calls changing to WDOX in September 2006. The call letters were a reference to its moniker "Home of the Docs", as it aired programming featuring Dr. Laura Schlessinger and Dr. Joy Browne . In addition, WDOX was also home to local and regional programming such as "State Government Radio" and "Triangle In-Touch". On weekends, the station offered "Million Dollar Music", featuring musical favorites dating back to

1350-422: The comedy format, and began simulcasting full-time the news/talk programming of co-owned WPTF in Raleigh. On November 15, 2017, the station returned to the call letters WQDR and a classic country format, "Just Right Country", featuring songs "from the sixties to the nineties and beyond". On June 4, 2019, WQDR flipped to hot adult contemporary , branded as "Star 92.9" (in reference to FM translator W225DF that

1404-441: The construction permit and was broadcasting from its new site. The three towers at its former Shoccoree Drive transmitter site were removed in late October/early November 2017. On May 1, 2018, WDNC rebranded from "The Buzz" (which continued on WCMC-FM HD2 and the 96.5 and 99.3 translators) to "The Ticket" (which moved from WCLY, which flipped to adult album alternative). On July 31, 2022, WDNC switched back to "The Buzz" branding, in

1458-472: The day even more memorable was that WDNC's old 1490 dial position was immediately occupied by a new station, WSSB (now WDUR ). In 1952, WDNC's parent company, the Herald-Sun Newspapers, applied to build a TV station in Durham on the city's newly allotted VHF channel 11. The owners of cross-town competitor WTIK had also applied for channel 11. The two parties later joined their efforts under

1512-440: The event being counted may be a complete cycle); 100 Hz means "one hundred periodic events occur per second", and so on. The unit may be applied to any periodic event—for example, a clock might be said to tick at 1 Hz , or a human heart might be said to beat at 1.2 Hz . The occurrence rate of aperiodic or stochastic events is expressed in reciprocal second or inverse second (1/s or s ) in general or, in

1566-644: The gaps in the main signal. On April 25, 2017, the Federal Communications Commission issued a construction permit for Capitol Broadcasting to move WDNC's transmitter from the station's long-time West Durham location on Shocorree Drive to a diplex arrangement with WDUR 1490 AM, at the latter's transmitter site on Nixon Street in southeastern Durham. This also authorized WDNC to reduce its 5,000 watt daytime power to 1,500 watts non-directional, and its 1,000 watt nighttime power to 41 watts non-directional. By late June 2017, WDNC had built out

1620-449: The hertz has become the primary unit of measurement accepted by the general populace to determine the performance of a CPU, many experts have criticized this approach, which they claim is an easily manipulable benchmark . Some processors use multiple clock cycles to perform a single operation, while others can perform multiple operations in a single cycle. For personal computers, CPU clock speeds have ranged from approximately 1 MHz in

1674-413: The highest normally usable radio frequencies and long-wave infrared light) is often called terahertz radiation . Even higher frequencies exist, such as that of X-rays and gamma rays , which can be measured in exahertz (EHz). For historical reasons, the frequencies of light and higher frequency electromagnetic radiation are more commonly specified in terms of their wavelengths or photon energies : for

1728-845: The incident involving the Rutgers women's basketball team . Imus replaced Mike and Mike in the Morning as WDNC de-emphasized ESPN Radio programming. On August 10, 2009, Curtis Media (which still owned the station) sold WDNC and sister station WCLY to Capitol Broadcasting Company, in exchange for the North Carolina News Network . The move enabled Capitol to concentrate its sports programming across three channels, with WDNC and WCMC-FM receiving some carry-over programming from WRBZ (which Curtis Media received from McClatchey Broadcasting), while WCLY would carry Spanish-language sports programming from ESPN Deportes Radio . WDNC

Various computer buses , such as the front-side bus connecting the CPU and northbridge , also operate at various frequencies in the megahertz range. Higher frequencies than the International System of Units provides prefixes for are believed to occur naturally in the frequencies of

1836-572: The meantime, the station would operate from the basement of the new Herald-Sun building. Capitol redubbed the station the "Smart Choice for News and Sports", and, in late 1995, implemented an all-news format under the handle, "The News Station", using the Associated Press ' all-news network supplemented with reports from the WRAL-TV newsroom. After three years, the agreement proved non-profitable for CBC. In 1997, Curtis Media Group took over

1890-406: The newspaper abandoned their downtown building for a new facility at 2828 Pickett Road in southwestern Durham. Shortly thereafter, the newspaper, wanting to focus more on its publishing divisions, put the two radio properties on the market. It was around this time that radio ownership rules were being relaxed. WDCG was sold in 1993, but there were no takers for WDNC. In 1994, the company entered into

1944-479: The next day, which was Leap Day , WDNC abandoned its 1490 dial position and 250-watt signal for a new three-tower directional array on Shocoree Drive in western Durham which operated with 5,000 watts daytime and 1,000 watts nighttime at a new frequency on the other end of the dial, 620 AM. Leap Day 1948 turned out to be a very eventful day in Durham broadcasting history: As WDNC fired up their new, more powerful plant, they also signed on WDNC-FM, at 105.1 MHz. Making

1998-555: The problems of blacks. In 1997, WLLE was purchased by Mortenson Broadcasting of Kentucky, who changed its call letters to WRDT and began airing religious talk. Two years later, the station was picked up by Curtis Media and the call letters were changed once again to WDTF, continuing on with the religious talk format and adding inspirational music to the mix. In 2003, the station changed its format to current general talk and call letters to WDNZ to match its one-time simulcast partner, Durham-based WDNC . The station continued to air much of

2052-664: The quantum-mechanical vibrations of massive particles, although these are not directly observable and must be inferred through other phenomena. By convention, these are typically not expressed in hertz, but in terms of the equivalent energy, which is proportional to the frequency by the factor of the Planck constant . The CJK Compatibility block in Unicode contains characters for common SI units for frequency. These are intended for compatibility with East Asian character encodings, and not for use in new documents (which would be expected to use Latin letters, e.g. "MHz"). WDNC What

2106-564: The rules for capitalisation of a common noun ; i.e., hertz becomes capitalised at the beginning of a sentence and in titles but is otherwise in lower case. The hertz is named after the German physicist Heinrich Hertz (1857–1894), who made important scientific contributions to the study of electromagnetism . The name was established by the International Electrotechnical Commission (IEC) in 1935. It

2160-494: The same programs as WDNC, save for mornings and sports broadcasts featuring the Carolina Mudcats , even though both stations had aired Charlotte Bobcats games briefly. All that changed in late 2005 when WDNC broke off the simulcast to become an all-sports station with an entirely separate staff, LMAed by McClatchey Broadcasting, owners of WRBZ , 850 AM. The general talk format continued on WDNZ after that point, with

2214-598: The schools and the death of Martin Luther King Jr. His style came from Douglas "Jocko" Henderson of Philadelphia and Durham's Dr. Jive of WSRC . WLLE was the first radio station in the state to interview Coretta Scott King and the first black radio station to interview a grand dragon of the Christian Knights of the Ku Klux Klan .

Whereas 1 Hz (one per second) specifically refers to one cycle (or periodic event) per second, 1 Bq (also one per second) specifically refers to one radionuclide event per second on average. Even though frequency, angular velocity , angular frequency and radioactivity all have the dimension T , of these only frequency is expressed using

2376-508: The station for Raleigh's black community, and it was the second most popular AM station. In 1977 the Federal Communications Commission (FCC) revoked WLLE's license, after an investigation begun in 1973 determined that the station had engaged in improper billing practices. The station was allowed to continue broadcasting while it appealed this ruling, and the legal proceedings did not end until October 1979, when

2430-409: The station's call sign was changed to WSHE. One provision of the station sale was that B. H. Ingle would continue to have one half-hour of air time each weekday from 10:30 to 11:00 a.m. for a religious program, which was later modified to the last half-hour of each broadcast day. However, as of August 17, 1959, station management barred Ingle from making any further broadcasts, on the grounds that he

2484-446: The station's studios were moved into the Herald-Sun's building at 138 East Chapel Hill Street, literally next door to the Washington Duke Hotel. In 1938, WDNC increased its power from 100 to 250 watts. The NARBA frequency realignment of 1941 saw the station relocate to 1490 AM. During this time, their antenna was located near present-day Forest Hills Park on South Street. WDNC's last broadcast from this site came on February 28, 1948. On

The correspondence between a frequency f with the unit hertz and an angular velocity ω with the unit radians per second is The hertz is named after Heinrich Hertz . As with every SI unit named for a person, its symbol starts with an upper case letter (Hz), but when written in full, it follows

2592-430: Was acquired the previous month, and began simulcasting the new format upon launch). Also timed with the new format, the station took call sign WPLW from its sister hit music station, WPLW-FM . "Star" was the Triangle affiliate of The Bob and Sheri Show . On December 28, 2020, at Midnight, WPLW and W225DF flipped to classic rock as "Rock 92.9". The first song on "Rock 92.9" was " Tom Sawyer " by Rush . The call sign

2646-490: Was adopted by the General Conference on Weights and Measures (CGPM) ( Conférence générale des poids et mesures ) in 1960, replacing the previous name for the unit, "cycles per second" (cps), along with its related multiples, primarily "kilocycles per second" (kc/s) and "megacycles per second" (Mc/s), and occasionally "kilomegacycles per second" (kMc/s). The term "cycles per second" was largely replaced by "hertz" by

2700-429: Was advertised as "Hillbilly, Western, and Gospel music, Associated Press news, weather reports and news of local and county interest". The debut broadcast scheduled for October 17 had to be delayed by eight days due to damage from Hurricane Hazel . In late 1955 an application was made to transfer station ownership to Merchants & Farmers Radio Station WMSN Inc., for "$ 8,000 plus other considerations", and in early 1959

2754-512: Was badly damaged by a tornado . Following numerous delays in securing a new transmitter site, the station eventually returned to the airwaves on February 22, 2012, transmitting from one of the towers of sister station's WPTF transmitter site in Cary. At that time, the station began to air an all-comedy format under the moniker "Funny 570", and its call letters were changed to WFNL, which stood for "We're Fun N Laughs". The station initially served as

2808-726: Was carrying on "an attack on many forms of organized religion, and a denunciation of laymen and ministers holding religious beliefs other than which you have". In 1962 the station was sold by Raleigh Broadcasting Corp. to the Raleigh-Durham Broadcasting Company for $ 180,000. The station made its debut as WLLE on February 15, 1962, and became known as "Hot 57", Raleigh's home for rhythm and blues. Also known as "Wonderful Willie", WLLE played James Brown , Little Richard , The O'Jays , and Earth Wind & Fire , and it could be heard as far away as Walkertown and Wallace-Rose Hill . Its DJs included Oscar "Daddy O on
