Wax nostalgic about and learn from the history of early electronics. See articles from Radio & Television News, published 1919-1959. All copyrights hereby acknowledged.

Belmont Radio Corporation was located in Chicago, Illinois. Founded independently sometime the 1920s, it became a subsidiary of Raytheon Manufacturing after World War II in an effort to quickly launch Raytheon into the nascent consumer FM radio and television markets. Belmont advertisements were prominent in electronics trade magazines throughout 1940 to promote their war efforts. A schematic and parts list for this Belmont Model 5240 vacuum tube radio appeared in the July 1948 edition of Radio News magazine. I could not find an example of the radio anywhere. Based on the schematic, my guess is it was a tabletop model. Please let me know if you know where there is a photo of one.

Belmont Radio Corporation: A Brief Overview and Historical Context

Belmont Radio was a leading American manufacturer of radio equipment during the 1920s and 1930s. The company was founded in Chicago, Illinois, in 1923, by Harold J. Belmont, and quickly became one of the largest radio manufacturers in the United States.

Belmont Radio was known for producing high-quality, affordable radio sets that were designed for both residential and commercial use. The company's radios were characterized by their distinctive cabinet designs, which were made from beautiful, handcrafted woods and came in a variety of styles and finishes. Belmont Radio's radios were also equipped with advanced technology, such as high-voltage power supplies, which allowed them to produce clear, powerful sound.

Belmont Radio was a major player in the commercialization of radio, and the company played a key role in the growth of the radio industry during the 1920s and 1930s. The company was an early adopter of the use of advertising to promote its products, and its innovative marketing campaigns helped to bring radio to a wider audience. Belmont Radio also played a role in the establishment of the National Broadcasting Company (NBC), which was founded in 1926, and was a major factor in the growth of commercial radio broadcasting.

In addition to its contributions to the radio industry, Belmont Radio was also a leader in the development of new technology. The company was one of the first to develop the "breadboard" radio set, which was easy to assemble and repair. This innovation made radio more accessible to a wider audience and helped to increase the popularity of radio as a means of communication and entertainment.

Despite its success, Belmont Radio faced challenges during the Great Depression, and the company eventually merged with another radio manufacturer in the 1930s. However, the legacy of Belmont Radio continues to be felt today, and the company's impact on the radio industry is still remembered.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
