Submariner Frequency Converter, Model S, 1928-1935
01
Artifact Overview
Shortwave radio made it possible to bring the world into the living room. This device, used to alter any radio receiver, would have appealed to listeners hoping to hear beyond local and regional broadcast ranges. The ability of short wavelength radio waves to travel long distances through saltwater made this band useful for submarine communications, hence the "Submariner" brand name.
