FM radio five-station relay testIn 1940, Edwin H. Armstrong demonstrated the first “network” relay of an FM radio broadcast through several stations from Yonkers, N.Y., via Alpine, N.J., Meriden, Conn., and Paxton, Mass. to Mount Washington. Next the signal was relayed by the ordinary method to Winchester, Mass., then by telephone wire to the Yankee network headquarters in Boston, Mass. From Yonkers to Mount Washington, the broadcast needed no wire. The 60-minute program included selections by various musical instruments to test fidelity, free from static, distortion, fading and interference. It was exactly 17 years since the first network broadcast via telephone wires from New York to Boston on 4 Jan 1923. The following day, 5 Jan 1940, a similar demonstration was made for representatives of operators in the FM Broadcasters group.«[Image: Armstrong's 425-ft tower, Alpine, NJ, still serviceable.] |
