J HAT will be the favorite clry cult this coming season is JL—J a question asked by many interested in radio. The replies from some seem to say superheterodyne is bound to be it; others claim much for the multi-tube reflex circuits and say their economy is a point which is much sought for by all; still others claim a form of tuned radio frequency receiver, somewhat on the order of the neutrodyne, but without its bad features, will take the country by storm. It goes without question that last season was a neutrodyne season and they performed very well when It is considered that in thg great majority of cases the sets were being operated while improperly neutralized. Manufacturers have realized that present methods of neutralization left much to be desired. It could not be done by the average man; an attempt would be made, but the Job was seldom finished to his satisfaction. The feeling that It wasn’t exactly right was ever present, and the feeling was usually right. Neutralizing by means of compensating colls is being used with much satisfaction, and the process is truly a simple one, and now comes a receiver employing two stages of tuned radio frequency, detector and two stages of audio frequency amplification, but without any compensating condensers or coils—in the talk of the radio shop, nothing to fuss with. This new receiver is known as the Freshman Masterpiece and-was developed by A. W. Franklin, chief engineer of the Charles Freshman

He has produced and directed several successful productions. This experience enables him to suit his introductions to the types of features that follow. „

Company, New York City. This receiver utilizes specially designed coupling coils, wound in such a manner so as to reduce capacities and losses to a minimum, and has a close coupling between the primary and secondary windings which prevents or reduces oscillations to a minimum. Previous forms of tuned radio frequency receivers used a comparatively loose coupling, which had a tendency to make the set oscillate. In tuning the set it Is best to set the two dials, which should be of vernier type, in the radio frequency circuit to the highest point usually used, and then try tuning in a station by turning the first dial, which Is In the aerial circuit, slowly until the station is heard. If there Is no station broadcasting on that wave the two dials should then be turned down two divisions and the antenna dial again moved to within approximately ten divisions of the same. setting. It will be noticed the scale readings on all three dials are approximately the same on the various wave lentghs. Once a station is logged it may always be brought in on the same dial setting by referring to the log furnished with the receiver.

. What Radio Men Are Saying I believe we are going to be able to overcome static anil fading to a great extent. I believe in the next few years it will be done.—Alfred N. Goldsmith, prominent radio engineer. • • Like the telephone, the automobile, the motion picture, radio has passed beyond the stage of being \nerely an instrument Os enjoyment for those who can afford it. A,t its present rate of progress, radio is approaching the point where it will be regarded as a public utility.—William H. Priess, radio engineer. tat It will be a bad thing for radio as a whole to be subject to detailed laws and regulations which cannot be changed except through international agreement or other act of Congress. Through the annual national conferences a means is afforded for the radio industry to become self-regulating to a very high degree.—George S. Davis, general manager, radio telegraph department, United Fruit Company.
