Homebrew is an amateur radio slang term for home-built, noncommercial radio equipment. [1] Design and construction of equipment from first principles is valued by amateur radio hobbyists, known as "hams", for educational value, and to allow experimentation and development of techniques or levels of performance not readily available as commercial products.
The short wave station, 2XAL, increased its power to 15,000 watts. The radio station's format was changed; the jazz music was prohibited and replaced with presentations devoted to aviation and aviators. On a show about women aviators, Amelia Earhart recounted her recent transcontinental flight. The station gave hourly weather reports of aviators.
Curtain arrays were originally developed during the 1920s and 1930s when there was a lot of experimentation with long distance shortwave broadcasting. The underlying concept was to achieve improvements in gain and/or directionality over the simple dipole antenna, possibly by folding one or more dipoles into a smaller physical space, or to arrange multiple dipoles such that their radiation ...
Vintage amateur radio is a subset of amateur radio hobby where enthusiasts collect, restore, preserve, build, and operate amateur radio equipment from bygone years, such as those using vacuum tube technology.
The 15-meter band (also called the 21-MHz band or 15 meters) is an amateur radio frequency band spanning the shortwave spectrum from 21 to 21.45 MHz. The band is suitable for amateur long-distance communications, and such use is permitted in nearly all countries.
By 1928, RCA had scrapped plans for more longwave transmitters and instead built six shortwave transmitters, 2XT and WTT at 40 kw and WBU, WIK, WQO and WLL at 20 kw. The Radio Central complex was used to relay international broadcast programming received by, or sent from, RCA's broadcast stations in the United States.

Grundig Satellit 400 solid-state, digital shortwave receiver, c. 1986 [1]. Shortwave radio is radio transmission using radio frequencies in the shortwave bands (SW). There is no official definition of the band range, but it always includes all of the high frequency band (HF), which extends from 3 to 30 MHz (approximately 100 to 10 metres in wavelength).
