WLLH
WLLH (1400 AM) is a commercial radio station in the Merrimack Valley region of Massachusetts. The station is owned by Gois Broadcasting, LLC, and airs a tropical music radio format. There were actually two transmitters with the call sign WLLH. Both operated at 1,000 watts using non-directional antennas on AM 1400. One was in Lowell, and there was a synchronous transmitter in Lawrence, together forming the two Ls in the call sign. (There were once plans for a transmitter in Haverhill, — the H — but it was not built.) The station has shut off the Lowell transmitter and change the City of License to Lawrence. The Lowell transmitter was on the Merrimack River, next to the VFW Highway. The Lawrence transmitter is about 10 miles away, on Common Street, near the Lawrence Police Department Headquarters. WLLH is also heard on FM translator W236CU at 95.1 MHz in Lowell, with its 70–watt transmitter located off Holmes Road. The station uses its translator frequency in ...

WAMG
WAMG (890 AM; "La Mega") is a radio station in the Boston market licensed to Dedham, Massachusetts. It is owned by Gois Broadcasting. It broadcasts in Spanish, and plays bachata, merengue, salsa and pop music. WLS in Chicago is the dominant (class A) station on 890 AM; WAMG must reduce power during the nighttime hours and uses a directional antenna to protect the nighttime skywave signal of WLS. WAMG also simulcasts its programming on WLLH (1400 AM) in Lowell and Lawrence to reach the area north of Boston and the southern part of New Hampshire. It also operates translator W235CS (94.9 FM) in Dedham. History WAMG first came on the air in 1994 as WBMA, initially airing a Spanish-language religious format that gradually migrated from WBIV (now WQOM). In 1995, the station adopted a sports format, affiliated with the Prime Sports network. The station also adopted the call letters of WBPS at this time, which remained with the station for many years, even after the station dr ...

Transmitter
In electronics and telecommunications, a radio transmitter or just transmitter is an electronic device which produces radio waves with an antenna. The transmitter itself generates a radio frequency alternating current, which is applied to the 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, such as radio and television broadcasting stations, cell phones, walkie-talkies, 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 purposes; or radiolocation, such as radar and navigational transmitters. Generators of radio waves for heating or industrial purposes, such as microwave ovens or diathermy equipment, are not usually called transmi ...

Call Sign
In broadcasting and radio communications, a call sign (also known as a call name or call letters—and historically as a call signal—or abbreviated as a call) is a unique identifier for a transmitter station. A call sign can be formally assigned by a government agency, informally adopted by individuals or organizations, or even cryptographically encoded to disguise a station's identity. The use of call signs as unique identifiers dates to the landline railroad telegraph system. Because there was only one telegraph line linking all railroad stations, there needed to be a way to address each one when sending a telegram. In order to save time, two-letter identifiers were adopted for this purpose. This pattern continued in radiotelegraph operation; radio companies initially assigned two-letter identifiers to coastal stations and stations onboard ships at sea. These were not globally unique, so a one-letter company identifier (for instance, 'M' and two letters as a Marcon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Omnidirectional Antenna
In radio communication, an omnidirectional antenna is a class of antenna which radiates equal radio power in all directions perpendicular to an axis (azimuthal directions), with power varying with angle to the axis ( elevation angle), declining to zero on the axis. When graphed in three dimensions ''(see graph)'' this radiation pattern is often described as ''doughnut-shaped''. Note that this is different from an isotropic antenna, which radiates equal power in ''all'' directions, having a ''spherical'' radiation pattern. Omnidirectional antennas oriented vertically are widely used for nondirectional antennas on the surface of the Earth because they radiate equally in all horizontal directions, while the power radiated drops off with elevation angle so little radio energy is aimed into the sky or down toward the earth and wasted. Omnidirectional antennas are widely used for radio broadcasting antennas, and in mobile devices that use radio such as cell phones, FM radios, w ...

Synchronization In Telecommunications
Many services running on modern digital telecommunications networks require accurate synchronization for correct operation. For example, if telephone exchanges are not synchronized, then bit slips will occur and degrade performance. Telecommunication networks rely on the use of highly accurate primary reference clocks which are distributed network-wide using synchronization links and synchronization supply units. Ideally, clocks in a telecommunications network are synchronous, controlled to run at identical rates, or at the same mean rate with a fixed relative phase displacement, within a specified limited range. However, they may be mesochronous in practice. In common usage, mesochronous networks are often described as ''synchronous''. Components Primary reference clock (PRC) Modern telecommunications networks use highly accurate primary master clocks that must meet the international standards requirement for long term frequency accuracy better than 1 part in 1011.

Tropical Music
Tropical music ( es, música tropical) is a term in the Latin music industry that refers to music genres deriving from or influenced by the Spanish-speaking areas of the Caribbean. It includes the islands of Cuba, Puerto Rico, The Dominican Republic, and the Caribbean coastal regions of Colombia and Venezuela. In the 1940s and 1950s, the term tropical music was created to cover all music from the hispanophone Caribbean excluding Cuban music, which had its own category and niche within the American (and to a lesser extent European) music market. However, later in the 20th century after the Cuban Revolution, tropical music gained a broader meaning and began to be used in order to distinguish Caribbean genres such as cumbia and son cubano from inland genres such as tejano and norteño. Characteristics Due to its geographical roots, tropical music generally combines elements from European and African traditions. An example of this is the process of binarization of ternary rhythms b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haverhill, Massachusetts
Haverhill ( ) is a city in Essex County, Massachusetts, United States. Haverhill is located 35 miles north of Boston on the New Hampshire border and about 17 miles from the Atlantic Ocean. The population was 67,787 at the 2020 United States Census. Located on the Merrimack River, Haverhill began as a farming community of Puritans, largely from Newbury Plantation. The land was officially purchased from the Pentuckets on November 15, 1642 (One year after incorporation) for three pounds, and ten shillings. Pentucket was renamed Haverhill (after the Ward family's hometown in England) and evolved into an important industrial center, beginning with sawmills and gristmills run by water power. In the 18th and 19th century, Haverhill developed woolen mills, tanneries, shipping and shipbuilding. The town was home to a significant shoe-making industry for many decades. By the end of 1913, one tenth of the shoes produced in the United States were made in Haverhill, and because of this t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
