The textual matter herein is identical with that of these two volumes. The only changes made are in the Tables of Contents, the Appendixes, and the Indexes.

Radio station KDKA begins operations. In 1921, Westinghouse introduces the first factory-built radio receiver. Thus it was a premier technical authority about Radio as the U.S. entered the Second World War and needed to train soldiers. This book is designed to fit specialized wartime training requirements. Essentially, radio transmission consists of generating alternating currents of high frequency and introducing them into a conductor from which some of the electrical energy is thrown off in the form of electromagnetic waves. These waves travel through space, and some of their energy is absorbed by every electrical conductor they reach. If they reach a receiving antenna, they induce a current in it. This induced current then is detected, amplified, and converted into sound, whether it be voice, music, or dots and dashes.…
