The National Company of Malden, Massachusetts was a world-class manufacturer of commercial and amateur radio communications equipment from the early 1930s until the late 1960s. Their HRO series was used extensively by numerous allies during World War II, and can be credited with helping in the effort to receive coded messages from behind enemy lines. At the May 29 meeting of the Waltham Amateur Radio Association, George Maier, W1LSB, will take us through the company’s history, products, and talk about some National employees that he knew personally.For general information about the meeting, and the meeting before the meeting, see https://walthamara.org/meetings/ .
