But during nighttime hours the skywave radiations are reflected from the ionosphere, thereby creating the possibility of one station's rendering service, via skywave, at a much greater distance than it can through its groundwave signal, and at the same time vastly complicating the interference problem because of the still greater distance over which these skywave signals may cause interference to the signals of stations on the same and closely adjacent frequencies.

As interest in television grew, and as early television stations began regular broadcasts, the idea of networking television signals ( sending one station's video and audio signal to outlying stations ) was born.

One of 10 signal stations with telescopes making observation of the next station's signal, a message could be sent from the Admiralty to Portsmouth within 15 minutes.

The station's signal is relayed throughout Puerto Rico through two full-power satellite stations: WTIN-TV ( UHF digital channel 15, virtual channel 14. 1 ) in Ponce and WNJX-TV ( UHF digital channel 23, virtual channel 22. 1 ) in Mayagüez.

This station's digital signal is multiplexed:

The system used IBM punched cards to de-scramble a signal broadcast during the broadcast station's " off-time ".

As the antenna rotated through a fixed position, typically due north, the antenna was keyed with the morse code signal of the station's identification letters so the receiver could ensure they were listening to the right station.

Entercom has not filed with the FCC to do so and such a signal reduction has yet to be confirmed ; indications are that the station's signal strength and range has remained normal.

However, due to buffering of the digital broadcast on some computers, this signal may be delayed as much as 20 seconds from the actual start of the hour ( this is presumably the same situation for all CBS Radio stations, as each station's digital stream is produced and distributed in a similar manner ).

The station's digital signal is multiplexed:

This was the second incident of that night involving the interruption of a television station's broadcast signal, with the first taking place during WGN-TV ’ s News at Nine.

WGN-TV began broadcasting on cable television throughout the United States in October 1978, after Tulsa-based satellite uplinker United Video Satellite Group uplinked the station's signal via satellite.

This station's digital signal is multiplexed:

It is generally the area in which a station's signal strength is sufficient for most receivers to decode it, however this also depends on interference from other stations.

The " primary service area " is the area served by a station's strongest signal.

Those at the edge of a station's broadcast range will typically notice static in an analog broadcast, while error correction will keep a digital signal clear until it hits the cliff effect and suddenly disappears completely.

HD Radio switches back to the analog signal as a fallback when the edge of the digital range is encountered, but the success of this from the listener's perspective depends on how well the station's broadcast engineer has synchronized the two.

Instead, two stations were synchronized by using one of the two station's signal as the trigger for the second.

The ' TSL may return the same way as the studio / transmitter link ( STL ), or it can be embedded in the station's regular broadcast signal as a subcarrier ( for analog stations ) or a separate data channel ( for digital stations ).

The original antenna once carried the signal of WUPA TV 69 from the time it first went on-air as WVEU, but that station moved because the Westin tower lacked space for an antenna to send the station's digital television signal.

Developed jointly by IRT and Blaupunkt, it indicated the presence of traffic announcements through manipulation of the 57kHz subcarrier of the station's FM signal.

VOR stations broadcast a VHF radio composite signal including the station's identifier, voice ( if equipped ), and navigation signal.

He sucked in his breath and kept quiet while Killpath laid down the sheet again, wound the gold-wire stems of his glasses around his ears and then, eying the report as it lay before him on the desk, intoned, `` Acting Lieutenant Gunnar Matson one failed to see that the station keeper was properly relieved two absented himself throughout the entire watch without checking on the station's activities or the whereabouts of his section sergeants three permitted members of the Homicide Detail of the Inspector's Bureau to arrogate for their own convenience a patrolman who was thereby prevented from carrying on his proper assignment four failed to notify the station commander Acting Captain O. T. Killpath of a homicide occurring in the district five frequented extralegal establishments known as after-hours spots for purposes of an unofficial and purportedly social nature and six '' -- he leaned back and peeled off his glasses `` -- failed to co-operate with the Acting Captain by returning promptly when so ordered.

The station's new Main Building, which now houses the Immigration Museum, was opened in 1900.

In 2008, the museum's library was officially named the Bob Hope Memorial Library in honor of one the station's most famous immigrants.

He was also hired as the station's VP of Operations.

The station's first appearance in Star Trek: The Next Generation was during the sixth season episode " Birthright " and in addition, two Next Generation characters, Miles O ' Brien and ( from Season 4 onwards ) Worf, became regular members of DS9.

Armstrong ( and others ) eventually deduced that this was caused by a " supersonic heterodyne " between the station's carrier frequency and the oscillator frequency.

Severe damage was sustained during launch and deployment, including the loss of the station's micrometeoroid shield / sun shade and one of its main solar panels.

The most serious issue for reactivation was stationkeeping, as one of the station's gyroscopes had failed and the attitude control system needed refueling ; these issues would need EVA to fix or replace.

It was on September 4, 1882, that Edison switched on his Pearl Street generating station's electrical power distribution system, which provided 110 volts direct current ( DC ) to 59 customers in lower Manhattan.

Also discussed was how wattage power used by broadcasters would be distributed depending on the radio station's conditional use and location.

The South Wellfleet station's first call sign was " CC ", for Cape Cod.

WMAQ reporter Larry Langford, who was that station's overnight crime reporter and was known to cover all overnight police and fire activity for that station, reported that city crews were in the process of shutting down large water mains to see if the flow could be stopped.

A seventh station, WCVB-TV in Boston, was part of the original transaction but was spun off in a separate, concurrent deal to the Hearst Corporation as part of a right of first refusal related to that station's 1982 sale to Metromedia.

Afterward, WLPI-AM was shut down due to maintenance problems with the station's equipment.

The naming ceremony took place in his presence ; there was a last-minute scramble to repaint the station's new nameboards when it was discovered that the unusual dieresis in his name had been omitted ( making the French word for " welcome ").

The station dropped the 3GL call sign in favour of 3CAT, an ID that was proposed by the radio station's head of football commentary Ted Whitten ( who at the time was in the early stages of affliction of cancer ).

The station's building was evacuated and the fire was brought under control, though there is said to have been " extensive damage ", including smoke and water damage, to the studio.

The national entity was known as the CanWest Global System until adopting the Ontario station's branding in 1997.

More recently, with the exception of Global Toronto, stations now use sustained on-screen bugs using each station's full local brand as opposed to simply " Global ".

The City of Sanford assumed control of the former NAS Sanford in 1969 and renamed the facility Sanford Airport, hiring the air station's recently retired Executive Officer, Commander J. S. " Red " Cleveland, USN ( Ret.

The station's annual art auction has been on the air for 30 years and has been airing recently in September for three days.

The new owners changed the station's call letters to the present WPTZ ( for PlatTZburgh ); the WPTZ calls had recently been dropped by the channel 3 facility in Philadelphia following its controversial trade by Westinghouse Broadcasting to NBC earlier in that year.

It was one of the least used stations in the city at some point, but recently, industrial and residential projects in the area have increased the station's usage.

More recently, the station's branding has been extended to sister stations CKOF-FM in Gatineau, CKOY-FM in Sherbrooke, CFEL-FM in Quebec City and CKOB-FM in Trois-Rivières.

Since 1971, the station's original bijou ticket office building, built in 1878, has been used for other purposes, first as a burger bar and more recently a late night Kebab shop.

More recently, Electropop / Auto-tune singles have become the primary source of the station's playlist as several stations have started to move away from the heavy amount of Hip-Hop tracks that made up the format.

Most recently, the station added more 1990s and 2000s ( mostly from 2000-2004 ) rock songs by September 2009, reducing the classic rock lean, although like most of the station's life, they stayed mainstream rock.

Despite opposition from the Pleasant Hill City Council, the BART Board of Directors recently approved the station name change from " Pleasant Hill " to " Pleasant Hill / Contra Costa Centre " because of the station's proximity to the transit village.

He has recently joined Sydney community radio station 2SER 107. 3FM hosting the Wednesday breakfast program, where his insightful comments have endeared him to listeners as the station's own Hunter S. Thompson.
