WCAL (Minnesota)

	WCAL (Minnesota) WCAL was a non-commercial AM radio station licensed to Northfield, Minnesota, that was operated from its establishment in 1922 until its deletion in 1991 by St. Olaf College. History Following World War I, radio experimentation at St. Olaf began with physics experiments in 1918, when five students and a professor built a small transmitter, using a wire antenna strung between the campus chapel and the college's "Old Main" (the tallest nearby building). In 1921, the college was issued a "Technical and Training School" license with the call sign 9YAJ for the experimental operations, which began to include audio broadcasts in addition to the original Morse code transmissions. Initially there were no specific standards in the United States for radio stations making transmissions intended for the general public, and numerous stations under various classifications made entertainment broadcasts. However, effective December 1, 1921, the Department of Commerce, the regulators of radio at th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

The population was 20,790 at the 2020 census. History Northfield was platted in 1856 by John W. North. Local legend says that the town was named for John North and a Mr. Field. North, realizing that the town straddled the proposed northern border of Rice county, went to the state capital to lobby to move the border one mile north. Northfield was founded by settlers from New England known as "Yankees" as part of New England's colonization of what was then the far west. It was an early agricultural center with many wheat and corn farms. The town also supported lumber and flour mills powered by the Cannon River. As the "wheat frontier" moved west, dairy operations and diversified farms replaced wheat-based agriculture. The region has since moved away from dairy and beef operations. Today it produces substantial crops of corn and soybeans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

picture info	Radio Stations Disestablished In 1991 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 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
