The " LW " in the callsign is said to have stood for " London, Windsor ", considered to be the two chief cities in the station's listening area.

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.

And WWRL's colorful mobile unit, cruising predominately Negro neighborhoods, is a frequent reminder of that station's round-the-clock dedication to nonwhite interests.

The show is programed and written by the station's assistant continuity editor, Chuck Briefer.

The radio station's antenna is atop an apartment building owned by Montefiore Medical Center.

* 1986 – A tornado is broadcast live on KARE television in Minnesota when the station's helicopter pilot makes a chance encounter.

At the Kyle of Lochalsh, Palin bought the station's long metal platform sign and is seen lugging it back to London with him.

An emerging trend is to use the radio station's web site to provide in-depth coverage of news and advertisers headlined on the air.

The value of a station's advertising is set by the number, age and wealth of its listeners.

For most mainstream country stations, the emphasis is generally on current pop country, following the same process as top 40 ; the remaining music in a particular station's library generally uses music from the past fifteen years ( shorter for " hot country " or " new country " stations ), with the exact music used varying depending on the station and the style of music the listener wants to hear.

A station's value is usually measured as a percentage of market share in a market of a certain size.

There is no Canadian content requirement for talk radio, or " spoken word ," programming, unless the individual station's license expressly stipulates such a requirement ; most do not.

60 Minutes is also aired via CBS Radio on several of their radio stations at the same time as the television broadcast ( in each station's own local market ), such as WCBS in New York, KNX in Los Angeles, WBBM in Chicago, WWJ in Detroit, KCBS in San Francisco, and other stations owned by CBS.

For example, in North America FM radio stations in a single region cannot be licensed on adjacent frequencies — that is, if a station is licensed on 99. 5 MHz in a city, the frequencies of 99. 3 MHz and 99. 7 MHz cannot be used anywhere within a certain distance of that station's transmitter, and the second-adjacent frequencies of 99. 1 MHz and 99. 9 MHz are restricted to specialized usages such as low-power stations.

Coffey is chased by Bud and Lindsey in the station's other sub ; they manage to damage Coffey's sub, causing it to fall into the trench, where it is eventually crushed by the pressure and Coffey is killed.

The network has no digital on-screen graphic logo in the bottom right-hand corner of the screen on the HD feed, except for a ten-second promotional sweep of a Fox HD acknowledgement ( which before the end of 2010, also featured a sponsor tag for DirecTV ); instead a trigger in Fox's program delivery system at each station displays the affiliate station's logo bug in the 16: 9 right-hand corner of the screen, which disappears during commercial breaks ( during local pre-emptions of Fox programming the logo does remain on display even though the station is not airing the programming ).

In the film's climax, Vader throws Palpatine down the station's reactor core, killing him, and is mortally wounded in the process.

On arrival, the Millennium Falcon is captured by the space station's tractor beam.

In some municipalities of Western Finland it is allowed to use fireworks without a fire station's permission on the last weekend of August.

The station's studios and offices are located near Lincoln Square on the Upper West Side of Manhattan, adjacent to ABC's corporate headquarters, and its transmitter is atop the Empire State Building.

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.

To receive a station, an FM receiver is tuned to the center frequency of the station's channel.

She is granted the rank of lieutenant and remains on DS9 as station's Chief of Security.

Surrounded by forests, it offers swimming, fishing, sailing and surfing opportunities, and due to the power station's waste heat it is warm enough all year to be a habitat for grass carps.
