The popularity of “amateur” (home) radio skyrocketed during the 1920s, as broadcasting stations popped up across the country. This radio telephone and telegraph apparatus (DT-600), known as the Everyman Radio Receiver, was made by de Forest Wireless and used in homes to receive radio signals. The device is housed in a box with a removable lid, containing seven tuning coils. This set was modified by removing the bakelite panel and replacing it with a plastic panel to show the interior. The instructions, here set into the lid, made the set more accessible to the general public.
