Radio Digest (Oct 1923-July 1924)

RADIO DIGEST — Illustrated, October 20, 1923 PHILADELPHIA COPS TO TOTE AIRPHONES CARRY DEVICE ON BACKS, CHIEF PROPOSES Auxiliary Police Force of Radiophans Also Suggested by Quaker City Officials By W. E. Johnson PHILADELPHIA. — Police of Philadelphia soon will be walking their beats with tiny Radio sets strapped to their backs, by means of which they can be kept constantly in contact with headquarters, if the plans of Superintendent of Police Mills carry through. The superintendent, who has asked for a liberal appropriation out of the next municipal loan for construction of a city broadcasting station, explained today his plans to utilize Radio in a practical and larger way in the drive against crime. Each Cop to Get Set "We propose," he said, "to equip each policeman with a small portable set. Not only the patrolmen and traffic men would be so equipped, but all members of the force now assigned to keep moving about the city in automobiles watching for robbers and car thieves. "The plan contemplates the use of some sort of signals, perhaps a eiren during the day and a light at night, which would notify policemen throughout the city to listen in for instructions. A policeman on his beat could then obtain information as accurately and as promptly as if he were at his own particular station house. Every policeman in the city would be reached and instructed simultaneously. Would Have Citizens Aid "In time we hope to establish an auxiliary police force, composed of Radio enthusiasts, who will volunteer their services. There are in Philadelphia at least 200,000 sets. The police bureau could adopt a 'code for communication with trustworthy owners who have civic pride enough to co-operate with the force. "For instance, thieves representing themselves as electric, gas or telephone inspectors, at times gain entrance to dwellings to commit crimes. At once, upon receiving the description of such a criminal, the police bureau could send his description broadcast, asking the auxiliary force as well as the regular policemen to be on the lookout for him." COMPARES AIRPHONE TO VALUABLE VIOLIN Efrem Zimbalist, world famous violinist, listens in to the broadcast tones of a violin, comparing the reproduced sound with that from the one he has in his arms, a recently purchased $33,000 "Titian" Stradivarius. It is to be hoped that the test did not condemn Radio in the opinion of Zimbalist, who is a regular listener in © K & H. The station, if authorized, will be sufficiently powerful to reach New York, Chicago and the New England states. It probably will be located either atop the 547-foot city hall tower or on some hill in Fairmount park. Sweden Buys Most of U. S. Radio WASHINGTON, D. C. — Radio apparatus valued at $682,885, weighing 618,512 pounds, was exported from the United States during the month of July, according to a recent announcement by the Department of Commerce.

The annual "turn-over" of Radio personnel is large, due to several causes. Among them is the fact that many college men spend their summer vacations sailing the "briny deep" as marine Radio operators, and then return to their studies at the end of the season. It is reported that approximately 100 first-class Radio operators will be needed on government vessels alone during the next few months. On the first of last July, the government increased the pay of all its commercial operators approximately fifteen percent. The monthly rates of pay now in effect range from $85 to $125 a month. A few positions pay a higher salary. HOOVER LABELS NEW RADIO BILL WINNER Secretary of Commerce Sees Latest Measure Adopted by Both Houses WASHINGTON, D. C. — A new Radio bill will be introduced in the forthcoming session of Congress. It ts probable that the bill wiU be much simpler than the one passed by the house of representatives, but which failed of passage during the latest session because of the disapproval of the senate.

It is expected that Representative White, of Maine, who handled the bill in the house will again take charge. Mr. Hoover said recently that he did not believe there would be any trouble in having the biU passed during the coming session.
