WJAZ (Chicago)
WJAZ was the call sign used from 1922 to 1931 by a series of four separate, but closely related, broadcasting stations located in Chicago, Illinois and operated by the Chicago Radio Laboratory/Zenith Radio Corporations. The original WJAZ was first licensed in the summer of 1922, and the next year began broadcasting from the Edgewater Beach Hotel in Chicago. However, it was soon determined that a suburban transmitter location would be preferable, and Zenith began preparations to re-establish WJAZ's operations at a more suitable site. Following operation for a few weeks by the ''Chicago Tribune'' as WGN, the station license for the original WJAZ was sold to the hotel management, and the call letters changed to WEBH. In order to maintain control of the well-known WJAZ call sign until the new facility was ready, in 1924 Zenith briefly renamed a second Chicago station, WSAX, to WJAZ. Later that year, Zenith prepared a portable broadcasting station, mounted on a truck body, in order to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Marconi station ...

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] |

WCHI (1490 AM)
WCHI was a radio station in Chicago, Illinois, United States, that operated from January 1, 1925 until it was deleted in 1932. The station—owned by the Peoples Pulpit Association, a corporation of the Jehovah's Witnesses—was established as WORD in Batavia before moving to Chicago in 1930 and changing its call letters. At the time of its deletion, it was transmitting with 5,000 watts on 1490 kHz. Its license was revoked by the Federal Radio Commission (FRC) over its attacks on the medical profession and in order to allow another station full-time use of the 1490 kHz frequency. History Jehovah's Witnesses WCHI's initial license, with the call sign WORD, was issued to the Peoples Pulpit Association in Batavia, for a wavelength of 278 meters (1080 kHz) and a power of 500 watts. The station made its debut broadcast on January 1, 1925. The station aired evening programs including music and Bible lectures, with studios in Chicago's Webster Hotel.

General Order 40
The Federal Radio Commission's (FRC) General Order 40, dated August 30, 1928, described the standards for a sweeping reorganization of radio broadcasting in the United States. This order grouped the AM radio band transmitting frequencies into three main categories, which became known as Clear Channel, Regional, and Local. It also included provisions for coordination with Canadian station assignments. The majority of the reassignments resulting from the plan's implementation went into effect on November 11, 1928. Background Radio transmissions in the United States were originally regulated by the Department of Commerce, as authorized by the Radio Act of 1912. The first formal regulations governing broadcasts intended for the general public were adopted effective December 1, 1921. This initially established just two transmitting wavelengths — 360 meters (833 kHz) for "entertainment" broadcasts, and 485 meters (619 kHz) for "market news and weather reports". The number of ...
