Bakelite The availability of the first mass produced plastic Bakelite allowed designers much more creativity in cabinet styling, and significantly reduced costs. However, Bakelite is a brittle plastic, and dropping a radio could easily break the case. Bakelite is a brown-black mouldable thermosetting plastic, and is still used in some products today. In the 1930s some radios were manufactured using Catalin, a colourable version of bakelite, but nearly all historic bakelite radios are the standard black-brown bakelite colour. | ![]() |

The first radio receivers used a coherer and sounding board, and were only able to receive Morse code, and thump it out on the board. This type of transmission is called CW (Continuous wave) or wireless telegraphy. When wireless telephony (ie transmission & reception of speech) became possible, speech radio greatly improved the usability of radio communication. Despite this, the antiquated technology of morse code transmission continued to play an essential role in radio comms until the 1990s.
