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] |
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] |
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 ...

Armstrong Tower
The Armstrong Tower, also known as Alpine Tower, is a distinctive (425 foot) tall lattice tower featuring three large cross-arms, located atop the Alpine, New Jersey palisades overlooking the Hudson River a few kilometers north of New York City at 40°57'39.0" N and 73°55'21.0" W (40.9607 -73.9225).

Sackermann, Jr. The tower is the permanent transmitter site for locally based experimental station WA2XMN and Fairleigh Dickinson University's educational FM station WFDU, in additional to numerous directional radio services (including as a cell site). It is clearly visible from across the Hudson River and is used as a Visual flight rules waypoint by aircraft flying within the New York City Special flight rules area.

WA2XMN
WA2XMN is an experimental FM radio station which broadcasts sporadically from the Armstrong Tower in Alpine, New Jersey. The station commemorates the pioneering broadcasts of the world's first FM radio station, W2XMN, built by Edwin Howard Armstrong, which began experimental broadcasts from this tower in June 1938 followed by full power broadcasting beginning on July 18, 1939. Armstrong's station signed off as KE2XCC on March 6, 1954. WA2XMN broadcasts at 42.8 MHz, one of the frequencies used by Armstrong's station on the original 42-50 MHz FM broadcast band. Transmitting from near the top of the 425-foot tall Armstrong Tower, which sits on top of the 500-foot-tall Pallisades (for a total height of over 900 feet above mean sea level), WA2XMN has a listening range of roughly 60–100 miles. The building at the base of the tower still has the W2XMN call sign engraved above the entrance. The station signed on using a restored Phasitron transmitter built by Steve Hemp ...

Radio Stations Established In 1936
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 an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
