Earle J. Gluck
Earle Jackson Gluck (May 23, 1901 – February 19, 1972), was a radio and television pioneer. He was born in Baltimore, Maryland,"Earle Jackson Gluck" (obituary), ''Charlotte Observer'', February 21, 1972, page 6C. and in the summer of 1915 was issued an amateur radio station license with the call sign 3AIF, for use at his home in Hamilton. During World War I he served as a chief radioman for the U.S. Navy."Earle Gluck, Housing Chief Dies at 71 of Heart Attack" by Bradley Martin, ''Charlotte Observer'', February 20, 1972, page 1. He later moved to Charlotte, North Carolina, becoming a Westinghouse Electric and Manufacturing Company engineer, where he was relicensed as amateur station 4CQ. Most amateurs at this time used spark transmitters that could only transmit the dots-and-dashes of Morse code, however a Gluck associate, Fred Laxton, managed to acquire a scarce vacuum tube from General Electric, which made audio transmissions possible. Gluck and Laxton, along with Frank Bunker ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio
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, spacecraf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Morse Code
Morse code is a method used in telecommunication to encode text characters as standardized sequences of two different signal durations, called ''dots'' and ''dashes'', or ''dits'' and ''dahs''. Morse code is named after Samuel Morse, one of the inventors of the telegraph. International Morse code encodes the 26 basic Latin letters through , one accented Latin letter (), the Arabic numerals, and a small set of punctuation and procedural signals ( prosigns). There is no distinction between upper and lower case letters. Each Morse code symbol is formed by a sequence of ''dits'' and ''dahs''. The ''dit'' duration is the basic unit of time measurement in Morse code transmission. The duration of a ''dah'' is three times the duration of a ''dit''. Each ''dit'' or ''dah'' within an encoded character is followed by a period of signal absence, called a ''space'', equal to the ''dit'' duration. The letters of a word are separated by a space of duration equal to three ''dits'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WBT (AM)
WBT (1110 kHz) is a commercial AM radio station serving the Charlotte metropolitan area, including parts of North Carolina and South Carolina. First licensed on March 18, 1922, it is one of America's first radio stations. The station airs a news/talk radio format simulcast on WBT-FM (99.3) and the HD2 digital subchannel of co-owned WLNK. WBT is owned by Urban One. Studios and offices are located off West Morehead Street, just west of Uptown Charlotte, co-located with the city's CBS television affiliate, WBTV, currently owned by Gray Television but at one time co-owned with WBT Radio. WBT broadcasts 50,000 watts around the clock as the only Class A clear-channel station in the Carolinas. Its transmitter is in the southern part of the city off Nations Ford Road. During daylight hours it uses a single non-directional antenna and is audible in much of the central Carolinas. At night it uses a directional antenna that limits its signal toward the west, in order to avoid interferi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Civitan International
Civitan International, based in Birmingham, Alabama, is an association of community service clubs founded in 1917. The organization aims "to build good citizenship by providing a volunteer organization of clubs dedicated to serving individual and community needs with an emphasis on helping people with developmental disabilities." The organization includes 40,000 members (referred to as ''Civitans'') in almost 1,000 clubs around the world. History In 1917, a group of Birmingham, Alabama, businessmen were members of the local Rotary club. Many of the men thought that the club focused too much on increasing the business of club members, so they surrendered their club's charter. Led by Courtney Shropshire, a local doctor, they formed an independent service club named ''Civitan'', derived from the Latin word for ''citizenship''. The United States entered World War I just one month after the club formed. With all attention focused on the war, Civitan remained a local organization. Som ...

At the time, it was known as the Year of the Consulship of Magius and Rufinus (or, less frequently, year 950 '' Ab urbe condita''). The denomination 197 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
