The original call sign was WRCP-FM, simulcasting co-owned WRCP (AM) 1540 and its middle of the road (MOR) format. The stations were owned by Associated Communications, a subsidiary of the Rust Craft Greeting Card Company. In 1967, the stations switched to a country music format. Because the AM station was a daytimer, required to go off the air at sunset, WRCP-FM was able to continue the format into the evening. Tightened Federal Comm ...

Philadelphia, Pennsylvania
Philadelphia, often called Philly, is the largest city in the Commonwealth of Pennsylvania, the sixth-largest city in the U.S., the second-largest city in both the Northeast megalopolis and Mid-Atlantic regions after New York City. Since 1854, the city has been coextensive with Philadelphia County, the most populous county in Pennsylvania and the urban core of the Delaware Valley, the nation's seventh-largest and one of world's largest metropolitan regions, with 6.245 million residents . The city's population at the 2020 census was 1,603,797, and over 56 million people live within of Philadelphia. Philadelphia was founded in 1682 by William Penn, an English Quaker. The city served as capital of the Pennsylvania Colony during the British colonial era and went on to play a historic and vital role as the central meeting place for the nation's founding fathers whose plans and actions in Philadelphia ultimately inspired the American Revolution and the nation's inde ...

Sign-on
A sign-on (or start-up in Commonwealth countries except Canada) is the beginning of operations for a radio or television station, generally at the start of each day. It is the opposite of a sign-off (or closedown in Commonwealth countries except Canada), which is the sequence of operations involved when a radio or television station shuts down its transmitters and goes off the air for a predetermined period; generally, this occurs during the overnight hours although a broadcaster's digital specialty or sub-channels may sign-on and sign-off at significantly different times as its main channels. Like other television programming, sign-on and sign-off sequences can be initiated by a broadcast automation system, and automatic transmission systems can turn the carrier signal and transmitter on/off by remote control. Sign-on and sign-off sequences have become less common due to the increasing prevalence of 24-hour-a-day, seven-day-a-week broadcasting. However, some national broadc ...

Sister Station
In broadcasting, sister stations or sister channels are radio or television stations operated by the same company, either by direct ownership or through a management agreement. Radio sister stations will often have different formats, and sometimes one station is on the AM band while another is on the FM band. Conversely, several types of sister-station relationships exist in television; stations in the same city will usually be affiliated with different television networks (often one with a major network and the other with a secondary network), and may occasionally shift television programs between each other when local events require one station to interrupt its network feed. Sister stations in separate (but often nearby) cities owned by the same company may or may not share a network affiliation. For example, WNYW and WWOR-TV, in New York City and Secaucus, New Jersey, are both owned by Fox Corporation. WNYW is a Fox owned-and-operated station; WWOR-TV is a MyNetworkTV own ...

Sports Radio
Sports radio (or sports talk radio) is a radio format devoted entirely to discussion and broadcasting of sporting events. A widespread programming genre that has a narrow audience appeal, sports radio is characterized by an often- boisterous on-air style and extensive debate and analysis by both hosts and callers. Many sports talk stations also carry play-by-play (live commentary) of local sports teams as part of their regular programming. Hosted by Bill Mazer, the first sports talk radio show in history launched in March 1964 on New York's WNBC (AM). Soon after WNBC launched its program, in 1965 Seton Hall University's radio station, WSOU, started ''Hall Line'', a call-in sports radio talk show focusing on the team's basketball program. Having celebrated its 50th anniversary on air during the 2015–2016 season, ''Hall Line'', which broadcasts to central and northern New Jersey as well as all five boroughs of New York, is the oldest and longest running sports talk call-in show i ...

Digital Subchannel
In broadcasting, digital subchannels are a method of transmitting more than one independent program stream simultaneously from the same digital radio or television station on the same radio frequency channel. This is done by using data compression techniques to reduce the size of each individual program stream, and multiplexing to combine them into a single signal. The practice is sometimes called "multicasting". ATSC television United States The ATSC digital television standard used in the United States supports multiple program streams over-the-air, allowing television stations to transmit one or more subchannels over a single digital signal. A virtual channel numbering scheme distinguishes broadcast subchannels by appending the television channel number with a period digit (".xx"). Simultaneously, the suffix indicates that a television station offers additional programming streams. By convention, the suffix position ".1" is normally used to refer to the station's main digi ...

HD Radio
HD Radio (HDR) is a trademark for an in-band on-channel (IBOC) digital radio broadcast technology. It generally simulcasts an existing analog radio station in digital format with less noise and with additional text information. HD Radio is used primarily by AM and FM radio stations in the United States, Canada, and Mexico, with a few implementations outside North America. The term "on channel" is a misnomer because the system actually broadcasts on the ordinarily unused channels adjacent to an existing radio station's allocation. This leaves the original analog signal intact, allowing enabled receivers to switch between digital and analog as required. In most FM implementations, from 96 to 128 kbps of capacity is available. High-fidelity audio requires only 48 kbps so there is ample capacity for additional channels, which HD Radio refers to as "multicasting". HD Radio is licensed so that the simulcast of the main channel is royalty-free. The company makes its money ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roxborough, Philadelphia
Roxborough is a neighborhood in the Northwest section of the city of Philadelphia, Pennsylvania. It is bordered to the southwest, along the Schuylkill River, by the neighborhood of Manayunk, along the northeast by the Wissahickon Creek section of Fairmount Park, and to the southeast by the neighborhood of East Falls. Beyond Roxborough to the northwest is Montgomery County. Roxborough's ZIP code is 19128. Most of Roxborough is in Philadelphia's 21st Ward. History The Native American trail called the Manatawny, now Ridge Avenue, was central to the well-organized development of farms and plantations within the area then known as Manatawna. The Court of Upland in England appointed local Swedish settler Peter Rambo to be the maintainer of the Manatawny road. In 1690, the road was renamed Ridge Road (it follows the crest of the ridge between the Wissahickon valley and the Schuylkill valley), and the area was renamed Roxburgh, likely named for Roxburghshire, Scotland, the ancestr ...

Radio Masts And Towers
Radio masts and towers are typically tall structures designed to support antennas for telecommunications and broadcasting, including television. There are two main types: guyed and self-supporting structures. They are among the tallest human-made structures. Masts are often named after the broadcasting organizations that originally built them or currently use them. In the case of a mast radiator or radiating tower, the whole mast or tower is itself the transmitting antenna. Terminology The terms "mast" and "tower" are often used interchangeably. However, in structural engineering terms, a tower is a self-supporting or cantilevered structure, while a mast is held up by stays or guys. Broadcast engineers in the UK use the same terminology. A mast is a ground-based or rooftop structure that supports antennas at a height where they can satisfactorily send or receive radio waves. Typical masts are of steel lattice or tubular steel construction. Masts themselves play no part in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transmitter
In electronics and telecommunications, a radio transmitter or just transmitter is an electronic device which produces radio waves with an antenna (radio), antenna. The transmitter itself generates a radio frequency alternating current, which is applied to the Antenna (radio), antenna. When excited by this alternating current, the antenna radiates radio waves. Transmitters are necessary component parts of all electronic devices that communicate by radio communication, radio, such as radio broadcasting, radio and television broadcasting stations, cell phones, walkie-talkies, Wireless LAN, wireless computer networks, Bluetooth enabled devices, garage door openers, two-way radios in aircraft, ships, spacecraft, radar sets and navigational beacons. The term ''transmitter'' is usually limited to equipment that generates radio waves for Communication engineering, communication purposes; or radiolocation, such as radar and navigational transmitters. Generators of radio waves for heatin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Effective Radiated Power
Effective radiated power (ERP), synonymous with equivalent radiated power, is an IEEE standardized definition of directional radio frequency (RF) power, such as that emitted by a radio transmitter. It is the total power in watts that would have to be radiated by a half-wave dipole antenna to give the same radiation intensity (signal strength or power flux density in watts per square meter) as the actual source antenna at a distant receiver located in the direction of the antenna's strongest beam (main lobe). ERP measures the combination of the power emitted by the transmitter and the ability of the antenna to direct that power in a given direction. It is equal to the input power to the antenna multiplied by the gain of the antenna. It is used in electronics and telecommunications, particularly in broadcasting to quantify the apparent power of a broadcasting station experienced by listeners in its reception area. An alternate parameter that measures the same thing is effec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bala Cynwyd
Bala Cynwyd ( ) is a community in Lower Merion Township, Pennsylvania. It is located on the Philadelphia Main Line in Southeastern Pennsylvania, bordering the western edge of Philadelphia at U.S. Route 1 (City Avenue). It was originally two separate towns, Bala and Cynwyd, but is commonly treated as a single community. This came about when a single U.S. Post Office served both towns (the Bala Cynwyd branch) using ZIP Code 19004. The community was long known as hyphenated Bala-Cynwyd. Bala and Cynwyd are currently served by separate stations on SEPTA's Cynwyd Line of Regional Rail. Description Bala Cynwyd lies in the Welsh Tract of Pennsylvania and was settled in the 1680s by Welsh Quakers, who named it after the town of Bala and the village of Cynwyd in Wales. A mixed residential community made up predominantly of single-family detached homes, it extends west of the Philadelphia city limits represented by City Avenue from Old Lancaster Road at 54th Street west to Meeting House ...
