Caldwell Proposes Method Of Reducing Interference By Synchronizing Stations By O.

H. CALDWELL, Federal Radio Commissioner for the Eastern District. THE problem with which the Commission has been struggling is essentially an engineering problem that of fitting onto 89 wave lengths some 700 broadcasting stations, big and little, so that there win be a minimum of Interference between those stations as received on listeners' sets.

A competent and lucent Washington, Oct. li Official opinion Is that President Coolidge nur wait far the convening of Congress before appointing a successor to Col. John F. Dillon.

Radio Commissioner from the Filth Zone, whose death occurred Last Sm.dav. Although no official comment 11 forthcoming from- the White House, there is reason to believe the President Is not entirely sure of the rcces-sity for a fifth commissioner at this time. The commission has succeeded in making temporary assignments which have decreased interference to some extent and its remaining function Is to sit as a semi-Judiciary bodv to decide upon matters brought before It. Another factor which has a bearing is the lack of funds available for use by the commission. In a last minute Jam.

Congress failed to appropriate sufficient money even to pay the salaries of the commissioners. Although It is not known whether the President has any one under consideration to succeed Colonel Dillon, it is said that a number of persons have been recommended for the post. ception of programs, free from hetero indicates the possibility of synchonls-ing stations further apart, at "non-cross-talk' distances, and transmitting different programs. Similar wire synchronizing of the setations is non-contemplated in several othtT loc-tions. When further developed this plan offers an economic solution ol the very serious problem of chain-program operation, where 20 to 40 channels are now sometimes tied up with an identical nroeram.

If such dyning and other forms of station interference, are promised by Commissioner Henry A. Bellow's of the ous engineer might sit down at bis library table of an evening and evolve very workable assignment of broadcast stations based upon elimination and time sharing.

And the Radio Commission, you must recall, did not take over the supervision of a situation that was In normal working order and had merely to be maintained with kid gloves.

Present Scheme Not Perfect. "The Commission realizes ouite wel; that the present wave length assignments are not perfect," says Mr. Bellows. "But it must be remembered that the job is a difficult one, that when the commission took it over everything was scrambled up because stations had been free to use any wave length they desired without any particular system.
