Description (Brief)
This Radio Data System (RDS) demonstration car radio was used in a 1995 ceremony on Capitol Hill marking the establishment of the 100th RDS-capable broadcast station, WKYS-FM in Washington, DC. RDS technology consisted of an inaudible text data stream transmitted from specially-equipped FM stations. The data included artist identification, community-service bulletins and traffic information. The demonstration receiver also includes a cassette tape deck with Dolby noise reduction. Engineer Ray Dolby designed a “sound compander” in the mid-1960s to improve audio output quality of recordings while working at Ampex and later founded a company to improve this technique.
