Historical Context:
The RCA RADA radio, also known as the Westinghouse RC, was the first commercial receiver sold by RCA. It combined the RA and DA chassis into a single common box, making it a significant innovation in early radio technology. The radio was designed for use with headphones or an external amplifier, and it played a crucial role in the early days of broadcast radio. Priced at $133.00 in its first year of sale, the RADA radio was a premium product aimed at enthusiasts and early adopters of radio technology.
