National Radio Company

Radio components were to play an important part in the company's growth in the mid-1920s as they moved into the large scale manufacture of capacitors.

It was at this time that two engineers from Harvard University, Fred H. Drake and Glen Browning, approached National to manufacture components to their specifications for a radio receiver of their own design.

This relationship led to the production and sale of the "National Regenaformer" kit for home construction of the Browning-Drake design.

By the early 1930s National had established a reputation with the amateur radio community based upon their line of regenerative receivers, including the SW-3 and SW-5.

National began providing equipment to the United States and Allied government customers such as the Royal Navy in 1939.
