RCA Institute, Inc. was an electronics school and subsidiary of the RCA Corporation, one of the country's leading manufacturers and vendors of radios, phonographs, televisions, and a wide array of consumer and military electronics products. The school specialized in basic electronics and electronics technology; computer technology; and courses for radio, television, and air‐conditioning servicing, as well as its traditional courses in amateur radio‐operator skills. These two educational instructional manuals were bound together. One focuses on RF-I transmitters, while the other concerns RF-II receivers. The laboratory manuals were intended to be guides for students at the RCA Institute in their work in the laboratory. They include questions and experiments to correlate to classroom lectures and practical work. The manuals' copyright dates are 1945 and 1946.
