KE2XCC
KE2XCC, first authorized in 1945 with the call sign W2XEA, was an experimental FM radio station located in Alpine, New Jersey and operated by inventor Edwin Howard Armstrong. It was located at the same site as Armstrong's original FM station, W2XMN, which dated to the late 1930s and primarily transmitted on the original FM "low band" frequencies. W2XEA was established as a companion station operating on the new FM "high band", which had been recently designated by the Federal Communications Commission as the replacement for the original FM station assignments. W2XMN shut down in 1949 after the "low band" was eliminated, and at this time W2XEA changed its call sign to KE2XCC and took over most of the functions previously performed by W2XMN. W2XEA was originally assigned to transmit on 92.1 MHz. This was changed in 1948 to 93.1 MHz, where it remained, as KE2XCC, until it ceased operations shortly after Armstrong's death in early 1954. In addition to general broadcasting to promote ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WFMN (Alpine, New Jersey)
WFMN (originally W31NY) was a commercial FM radio station located in Alpine, New Jersey. It was licensed from until around to inventor Edwin Howard Armstrong, and was co-located with two other Armstrong stations, W2XMN (until its suspension in 1949), and W2XEA/KE2XCC (1945-1954). However, for most of its existence WFMN was authorized for significantly lower power than the other two stations, and appears to have rarely been on the air. History In May 1940, the Federal Communications Commission (FCC) authorized an FM band effective January 1, 1941, operating on 40 channels spanning 42–50 MHz. (This was later changed to 88–106 MHz, and still later to 88–108 MHz, which increased the number of channels to 100.) At this time Edwin Howard Armstrong, the inventor of "wide-band" FM, was already operating experimental station W2XMN on 42.8 MHz, transmitting from a tower he had constructed a few kilometers north of New York City in Alpine, New Jersey.

W2XMN
W2XMN was an experimental FM radio station located in Alpine, New Jersey. It was constructed beginning in 1936 by Edwin Howard Armstrong in order to promote his invention of wide-band FM broadcasting. W2XMN was the first FM station to begin regular operations, and was used to introduce FM broadcasting to the general public in the New York City area. The station, in addition to being a testing site for transmitter and receiver development, was used for propagation studies and as an over-the-air relay station for distributing network programming to other FM stations in the region. W2XMN primarily operated on what became known as FM's "low band", mostly transmitting on 42.8 mc/s until December 1946, and on 44.1 mc/s thereafter. The station ceased operating in 1949, after the Federal Communications Commission (FCC) reassigned the "low band" frequencies to other services. At this point most of W2XMN's functions were inherited by Armstrong's "high band" FM station, KE2XCC, located at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edwin Howard Armstrong
Edwin Howard Armstrong (December 18, 1890 – February 1, 1954) was an American electrical engineer and inventor, who developed FM (frequency modulation) radio and the superheterodyne receiver system. He held 42 patents and received numerous awards, including the first Medal of Honor awarded by the Institute of Radio Engineers (now IEEE), the French Legion of Honor, the 1941 Franklin Medal and the 1942 Edison Medal. He was inducted into the National Inventors Hall of Fame and included in the International Telecommunication Union's roster of great inventors. Armstrong attended Columbia University, and served as a professor there for most of his life. Early life Armstrong was born in the Chelsea district of New York City, the oldest of John and Emily (née Smith) Armstrong's three children. His father began working at a young age at the American branch of the Oxford University Press, which published bibles and standard classical works, eventually advancing to the position of ...

WPAT-FM
WPAT-FM (93.1 FM) – branded "93.1 Amor" – is a radio station that programs a Spanish CHR radio format. Licensed to Paterson, New Jersey, the station is owned by the Spanish Broadcasting System and serves the New York metropolitan area. It has studios in Midtown Manhattan, and the transmitter is located at the Empire State Building. WPAT-FM broadcasts in HD. History WPAT-FM signed on in 1957 with studios in Newark, New Jersey. Its frequency of 93.1 MHz had previously been assigned to Edwin Howard Armstrong's Alpine, New Jersey station, KE2XCC, until it went off the air in 1954. This was the second station to hold the WPAT-FM call sign, as an earlier WPAT-FM, originally WNNJ, had operated on 103.5 MHz from 1949 until its deletion in early 1951. WPAT-FM eventually moved to studios on Church Street in Paterson, and later moved to studios at the four-tower transmitter site of its AM sister station at that time, 930 WPAT (AM), at 1396 Broad Street in Clifton, New J ...

Federal Communications Commission
The Federal Communications Commission (FCC) is an independent agency of the United States federal government that regulates communications by radio, television, wire, satellite, and cable across the United States. The FCC maintains jurisdiction over the areas of broadband access, fair competition, radio frequency use, media responsibility, public safety, and homeland security. The FCC was formed by the Communications Act of 1934 to replace the radio regulation functions of the Federal Radio Commission. The FCC took over wire communication regulation from the Interstate Commerce Commission. The FCC's mandated jurisdiction covers the 50 states, the District of Columbia, and the territories of the United States. The FCC also provides varied degrees of cooperation, oversight, and leadership for similar communications bodies in other countries of North America. The FCC is funded entirely by regulatory fees. It has an estimated fiscal-2022 budget of US $388 million. It has 1,482 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Multiplexing
In telecommunications and computer networking, multiplexing (sometimes contracted to muxing) is a method by which multiple analog or digital signals are combined into one signal over a shared medium. The aim is to share a scarce resource - a physical transmission medium. For example, in telecommunications, several telephone calls may be carried using one wire. Multiplexing originated in telegraphy in the 1870s, and is now widely applied in communications. In telephony, George Owen Squier is credited with the development of telephone carrier multiplexing in 1910. The multiplexed signal is transmitted over a communication channel such as a cable. The multiplexing divides the capacity of the communication channel into several logical channels, one for each message signal or data stream to be transferred. A reverse process, known as demultiplexing, extracts the original channels on the receiver end. A device that performs the multiplexing is called a multiplexer (MUX), and a dev ...

Radio Stations Established In 1945
Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is very widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, spacecraft a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
