Shelby, Montana
Shelby is a city in and the county seat of Toole County, Montana, Toole County, Montana, United States. The population was 3,169 at the 2020 United States census, 2020 census. History Shelby was named in honor of Peter O. Shelby, General Manager of the Montana Central Railway. A railroad station was established here about 1892, at the junction of the Great Northern Railway (U.S.), Great Northern Railway and the Great Falls & Canada Railway. On July 4, 1923, the town hosted a Jack Dempsey vs. Tommy Gibbons, heavyweight boxing match between Jack Dempsey and Tommy Gibbons for the undisputed world Heavyweight boxing championship title. This event almost bankrupted the town of Shelby. In the early 2000s the town hosted a dog camp that made national news. It was named Camp Collie and helped mistreated dogs. Welker Farms, an agricultural operation known for its popular social media channels, is located near Shelby. The Well Done Foundation, which plugs Orphaned wells in the United ...

Broadcast Relay Station
A broadcast relay station, also known as a satellite station, relay transmitter, broadcast translator (U.S.), re-broadcaster (Canada), repeater ( two-way radio) or complementary station (Mexico), is a broadcast transmitter which repeats (or transponds) the signal of a radio or television station to an area not covered by the originating station. These expand the broadcast range of a television or radio station beyond the primary signal's original coverage or improves service in the original coverage area. The stations may be (but are not usually) used to create a single-frequency network. They may also be used by an AM or FM radio station to establish a presence on the other band. Relay stations are most commonly established and operated by the same organisations responsible for the originating stations they repeat. Depending on technical and regulatory restrictions, relays may also be set up by unrelated organisations. Types Translators In its simplest form, a broadcast tra ...

List Of North American Broadcast Station Classes
This is a list of broadcast station classes applicable in much of North America under international agreements between the United States, Canada and Mexico. Effective radiated power (ERP) and height above average terrain (HAAT) are listed unless otherwise noted. All radio and television stations within of the US-Canada or US-Mexico border must get approval by both the domestic and foreign agency. These agencies are Industry Canada/ Canadian Radio-television and Telecommunications Commission (CRTC) in Canada, the Federal Communications Commission (FCC) in the US, and the Federal Telecommunications Institute (IFT) in Mexico. AM Station class descriptions All domestic (United States) AM stations are classified as A, B, C, or D. * A (formerly I) — clear-channel stations — 10 kW to 50 kW, 24 hours. **Class A stations are only protected within a radius of the transmitter site. **The old Class I was divided into three: Class I-A, I-B and I-N.

Facility ID
The facility ID number, also called a FIN or facility identifier, is a unique integer number of one to six digits, assigned by the U.S. Federal Communications Commission (FCC) Media Bureau to each broadcast station in the FCC Consolidated Database System (CDBS) and Licensing and Management System (LMS) databases, among others. Because CDBS includes information about foreign stations which are notified to the U.S. under the terms of international frequency coordination agreements, FINs are also assigned to affected foreign stations. However, this has no legal significance, and the numbers are not used by the regulatory authorities in those other countries. Current FCC practice is to assign facility ID numbers sequentially, but this is not an official requirement, so third-party users must not rely on it. Unlike call signs, however, the FIN associated with a particular station never changes; thus, the FCC staff and interested parties can be certain to which station an application p ...

Frequency
Frequency is the number of occurrences of a repeating event per unit of time. Frequency is an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena, such as mechanical vibrations, audio signals (sound), radio waves, and light. The interval of time between events is called the period. It is the reciprocal of the frequency. For example, if a heart beats at a frequency of 120 times per minute (2 hertz), its period is one half of a second. Special definitions of frequency are used in certain contexts, such as the angular frequency in rotational or cyclical properties, when the rate of angular progress is measured. Spatial frequency is defined for properties that vary or cccur repeatedly in geometry or space. The unit of measurement of frequency in the International System of Units (SI) is the hertz, having the symbol Hz. Definitions and units For cyclical phenomena such as oscillations, waves, or for examp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Call Signs In North America
Call signs are frequently still used by North American broadcast stations, in addition to amateur radio and other international radio stations that continue to identify by call signs worldwide. Each country has a different set of patterns for its own call signs. Call signs are allocated to ham radio stations in Barbados, Canada, Mexico and the United States. Many countries have specific conventions for classifying call signs by transmitter characteristics and location. The call sign format for radio and television call signs follows a number of conventions. All call signs begin with a prefix assigned by the International Telecommunication Union (ITU). For example, the United States has been assigned the following prefixes: AAA–ALZ, K, N, W. For a complete list, see international call sign allocations. Bermuda, Bahamas, and the Caribbean Pertaining to their status as former or current colonies, all of the British West Indies islands shared the VS, ZB–ZJ, and ZN–ZO prefixes ...

Tropospheric Ducting
Tropospheric propagation describes electromagnetic propagation in relation to the troposphere. The service area from a VHF or UHF radio transmitter extends to just beyond the optical horizon, at which point signals start to rapidly reduce in strength. Viewers living in such a "deep fringe" reception area will notice that during certain conditions, weak signals normally masked by noise increase in signal strength to allow quality reception. Such conditions are related to the current state of the troposphere. Tropospheric propagated signals travel in the part of the atmosphere adjacent to the surface and extending to some 25,000 feet (8 km). Such signals are thus directly affected by weather conditions extending over some hundreds of miles. During very settled, warm anticyclonic weather (i.e., high pressure), usually weak signals from distant transmitters improve in strength. Another symptom during such conditions may be interference to the local transmitter resulting in co-chann ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Tribune (San Luis Obispo)
''The Tribune'' is a semiweekly broadsheet newspaper and news website that covers San Luis Obispo County, California. History It was created in 1939 from a combination of three newspapers founded between 1869 and 1905, and was later acquired by the E. W. Scripps Company. Walter Murray led the establishment of ''The Tribune'' in the late 1860s, starting as the publication's editor and co-owner, with the first issue being printed on August 7, 1869. By 1886, the newspaper was produced above the Chicago Brewery Depot housed at the corner of Chorro and Monterey streets. In April 1939, it merged with the ''Telegram'', an anti-saloon newspaper in town, becoming the ''Telegram-Tribune''. The publication later moved from 1240 Morro Street to 1321 Johnson Avenue beginning in 1958, operating there for the next 35 years, before relocating once more to a new building, at 3825 S. Higuera Street, in 1993. Scripps traded the paper, along with '' The Monterey County Herald'', to Knight Ridder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
