A television station is a set of equipment managed by a business, organisation or other entity such as an amateur television (ATV) operator, that transmits video content and audio content via radio waves directly from a transmitter on the earth's surface to any number of tuned receivers simultaneously.
90-691: WIAT (channel 42) is a television station in Birmingham, Alabama , United States, affiliated with CBS and owned by Nexstar Media Group . The station's studios are on Golden Crest Drive atop Red Mountain , where its tower is also located. Channel 42 in Birmingham went on the air as WBMG on October 17, 1965, nearly nine years after its construction was approved. It was the city's third commercial station after channels 6 and 13 (now WBRC and WVTM-TV ), whose very high frequency (VHF) signals carried further than WBMG's ultra high frequency (UHF) signal;
180-631: A barter in some cases. Very high frequency Very high frequency ( VHF ) is the ITU designation for the range of radio frequency electromagnetic waves ( radio waves ) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter. Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high frequency (UHF). VHF radio waves propagate mainly by line-of-sight , so they are blocked by hills and mountains, although due to refraction they can travel somewhat beyond
270-629: A 15-year veteran of WVTM and sports talk radio host. The station also hired other longtime news presenters in Birmingham, including Ken Lass, Mark Prater, and David Neal. WIAT shut down its analog signal, over UHF channel 42, on June 12, 2009, the official date on which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal remained on its pre-transition UHF channel 30, using virtual channel 42. On May 7, 2012, LIN Media announced that it would purchase
360-556: A UHF channel was of note given that UHF television had proved mostly an economic failure due to lack of transmitter power and the inability of many sets to tune UHF stations. WSGN's owners, the Winston-Salem Broadcasting Company, withdrew their application for channel 42 on November 28, 1956. The withdrawal was part of a consolidation with the Balaban application, which was approved. Of the prospects for

His replacement was Eric Land, who arrived from WGRZ in Buffalo, New York . Among Land's first moves was simulcasting WBMG's newscasts on WNAL in Gadsden , which had replaced WJSU as the CBS affiliate in the eastern portion of the state. The station also ended its longtime relationship with UAB athletics; Broome,
540-631: A deal announced in August and completed in October 2006. After the sale, WIAT cemented itself as the number-three station in ratings. It debuted a full-fledged morning newscast in September 2007, and it began attracting noted news personalities under general manager Bill Ballard, who ran the station from 2003 to 2013. Herb Winches, a veteran Birmingham sportscaster for WBRC and WVTM, worked at channel 42 from 2007 to 2008 before being replaced by Jim Dunaway,
630-502: A far cry from the shares of 30 percent or above commanded by each of WBRC and WVTM. The newscasts were losing in the ratings to syndicated reruns on Birmingham's independent station , WTTO , though station management contended and a coincidental telephone survey found that viewership was higher than reflected in ratings diaries. John Herrod left KTXS-TV in Sweetwater, Texas , to become WBMG's news director in 1990. He sought to give
720-521: A major shakeup was fed by a major research project as well as the resignations of several senior managers over the course of 1997. On December 11, 1997, WBMG fired all of its on-air anchors and reporters as well as other news staffers, a total of 21 people, effective December 31. Land declared, "We just cannot continue to offer a traditional newscast. That's already being done in this market." The station's employees had expected Land to make significant changes. While lead weeknight anchorman Chris Schauble told

The station did not begin airing a local morning show until 2000, when it began simulcasting an hour of the morning show hosted by Russ and Dee Fine on WYDE radio. The station added a 6 p.m. evening newscast the next year. Land departed in 2001 when Media General tapped him to run WFLA-TV in Tampa, Florida , the company's flagship television property; he reunited with Cate, who had joined
900-415: A much shorter wavelength, and thus requires a shorter antenna, but also higher power. North American stations can go up to 5000 kW ERP for video and 500 kW audio, or 1000 kW digital. Low channels travel further than high ones at the same power, but UHF does not suffer from as much electromagnetic interference and background "noise" as VHF, making it much more desirable for TV. Despite this, in
990-508: A new Birmingham TV station pushed channel 42 into fourth place in news. When Media General acquired the Park group in 1997, it planned a major overhaul of the long-struggling station. General manager Eric Land fired all of WBMG's on-air presenters as well as other news employees in December 1997. For a month, channel 42 aired a countdown clock at 5 and 10 p.m. while the news department

I don't believe there are very many sets in use here which will bring in the UHF signal. And UHF operators elsewhere have had little luck in persuading folks to spend money to gear their sets to get UHF. But ... it costs money to keep an application alive, and something must be in

Land responded to Primo's scathing remarks by comparing the format to the Al Schottelkotte News , a longtime staple of WCPO-TV in Cincinnati from the 1960s until 1990, for which he had been a reporter: "[The Al Schottelkotte News] was very nontraditional, but jam-packed with information." 42 Daily News represented an immediate ratings improvement over its predecessor;
1260-500: A noted booster, was known for preempting CBS prime time programming for sports. Land's priority was to fix the news department; he had previously overseen major overhauls at WGRZ and at WEYI-TV in Saginaw, Michigan . The station's newscasts had sunk below The Andy Griffith Show on WTTO and Sanford and Son on WABM in the ratings, and they were so poor that not even the anchors' parents watched, Land later recalled. Speculation of

In addition, by 1985 the federal government decided new TV stations are to be broadcast on the UHF band. Two new VHF channels, 9A and 12, have since been made available and are being used primarily for digital services (e.g. ABC in capital cities) but also for some new analogue services in regional areas. Because channel 9A

VHF is the first band at which wavelengths are small enough that efficient transmitting antennas are short enough to mount on vehicles and handheld devices, a quarter wave whip antenna at VHF frequencies is 25 cm to 2.5 meter (10 inches to 8 feet) long. So the VHF and UHF wavelengths are used for two-way radios in vehicles, aircraft, and handheld transceivers and walkie-talkies . Portable radios usually use whips or rubber ducky antennas , while base stations usually use larger fiberglass whips or collinear arrays of vertical dipoles. For directional antennas,

The analog audio for TV channel 6 is broadcast at 87.75 MHz (adjustable down to 87.74). Several stations, known as Frankenstations , most notably those joining the Pulse 87 franchise, have operated on this frequency as radio stations, though they use television licenses. As

The VHF band is the first band at which efficient transmitting antennas are small enough that they can be mounted on vehicles and portable devices, so the band is used for two-way land mobile radio systems , such as walkie-talkies , and two way radio communication with aircraft ( Airband ) and ships ( marine radio ). Occasionally, when conditions are right, VHF waves can travel long distances by tropospheric ducting due to refraction by temperature gradients in

Helical and turnstile antennas are used for satellite communication since they employ circular polarization . For even higher gain, multiple Yagis or helicals can be mounted together to make array antennas . Vertical collinear arrays of dipoles can be used to make high gain omnidirectional antennas , in which more of

Older television sets using rotary dial tuners required adjustment to receive these new channels. Most TVs of that era were not equipped to receive these broadcasts, and so were modified at the owners' expense to be able to tune into these bands; otherwise
3150-592: The 10 p.m. newscast, in particular, had increased from a paltry 3% share in February 1997 to a 7% share in February 1998, partly due to having the Winter Olympics as a lead-in. This was not enough to overtake any competitors, but it was higher than the last newscasts as WBMG. Ratings also increased once Birmingham became a metered market, moving to 3 and 4 shares on most nights early in the fall of 1998, and continued their steady climb in early 1999. Some of

3420-551: The Birmingham Television Corporation, which built channel 42, had been unsuccessful in efforts to allocate a third VHF TV channel to Birmingham. The station initially aired the CBS and NBC programs not aired by channel 13 until the two stations each took full-time network affiliations in 1970. It was hemmed in by its weaker signal, the existence of CBS affiliates in Tuscaloosa and Anniston , and

That same month, Birmingham radio station WSGN filed for channel 42 as well. It was the second application for television made by WSGN, which had previously sought channel 48 and was an ABC affiliate in radio. The fact that two applicants were seeking

After purchasing LIN, Media General initially agreed to merge with the Meredith Corporation but faced a shareholder revolt in
3960-584: The U.S., the Federal Communications Commission (FCC) is taking another large portion of this band (channels 52 to 69) away, in contrast to the rest of the world, which has been taking VHF instead. This means that some stations left on VHF are harder to receive after the analog shutdown . Since at least 1974, there are no stations on channel 37 in North America for radio astronomy purposes. Most television stations are commercial broadcasting enterprises which are structured in

Other stations, including a variety of pay and regional free-to-air stations, were forced to broadcast in the UHF band, since the VHF band had been very overloaded with four stations sharing a very small frequency band, which was so overcrowded that one or more channels would not be available in some smaller towns. However, at

Finebaum left in May 2002 after a run of more than four years with channel 42; WIAT began broadcasting a digital signal, including high-definition programming, on November 20 of that year. Ratings growth leveled off after several years of the 42 Daily News format, and viewing figures remained flat between 2000 and 2003. While the reporter-less format cost the station less—the WIAT news department had 25 employees in 2003, compared to 70 at WBRC—it

In the late 1950s and early 1960s, the FCC considered adding such a channel to Birmingham on multiple occasions. In 1959, it considered moving channel 8 into Birmingham; WBMG favored a proposal to relocate channel 4 from Columbus, Mississippi , which

Certain subparts of the VHF band have the same use around the world. Some national uses are detailed below. The VHF TV band in Australia was originally allocated channels 1 to 10-with channels 2, 7 and 9 assigned for

VHF transmission range is a function of transmitter power, receiver sensitivity, and distance to the horizon, since VHF signals propagate under normal conditions as a near line-of-sight phenomenon. The distance to the radio horizon is slightly extended over the geometric line of sight to the horizon, as radio waves are weakly bent back toward the Earth by the atmosphere. An approximation to calculate
4500-776: The call letters. Micah Johnson, WIAT news manager On that date, at 5 p.m., viewers saw Land push a plunger to blow up the WBMG logo before an audience of Birmingham community leaders. The station changed its call sign to WIAT, for It's About Time, the slogan of the station's new 42 Daily News newscasts, which aired at 5 and 10 p.m. The Daily News format eschewed on-camera reporters; stories were packaged into topical minute segments such as "Alabama Minute" and "Education Minute". The format earned comparisons to CNN Headline News from Keith Cate , who came from WMAR-TV in Baltimore to serve as lead co-anchor, and an article in

They would act as full-power satellites of a low-power station in Birmingham, WBMA-LP , with a new combined news operation in Birmingham. The new station, which debuted in September 1996 under the moniker "ABC 33/40", featured veteran Alabama news personalities including WBRC's James Spann and Brenda Ladun, later poaching anchor Pam Huff from WVTM. The newscasts on WBMA immediately rose to third place in

In response to low ratings, the station dropped local news in 1982 and restored it in 1987; the newscasts, titled Action News Birmingham , became known for a combative style and emphasis on metro-area news, but they were never highly viewed. By 1997, syndicated reruns of Sanford and Son attracted more viewers than WBMG's evening news, and
4860-456: The early 2000s, the station moved to a more conventional format and brought in veteran Birmingham news personalities, which made channel 42 more competitive in the market. Media General acquired WVTM-TV in 2006 and sold WIAT to New Vision Television to make the purchase. LIN Media acquired New Vision in 2012, and Media General acquired LIN in 2014—this time, keeping WIAT and selling WVTM. Nexstar purchased Media General in 2017. In March 1956,

By this time, Tuscaloosa and Anniston each had their own stations: Tuscaloosa's WCFT (channel 33) debuted in October 1965, while Anniston's WHMA-TV (channel 40) started in October 1969. This situation persisted until May 31, 1970, when WAPI-TV became the sole NBC affiliate under a new agreement with NBC and WBMG the sole CBS affiliate. Likewise, WCFT and WHMA-TV became full-time CBS affiliates. In 1971, WBMG moved into larger studios on Red Mountain. Park Broadcasting,
