OLDER STATUS SHOULD ODTAIN -BESUENGTHS Waves Now Assigned Too Closely, Declares Crosley. Hu SEA Service NEW YORK. March >*s.—Rig.it of priority in the broadening .laid, is a basis for proper division of wave-lengths without interference at' .s ations, is suggested by Powell Crosley Jr. of Cincinnati. Crosley is chairman, of the committee on reallocation of wavelengths of the National Association of Broadcasters, and owner of station WLW, high power broadcaster at Cincinnati. “Right of priority is recognised in every field except radio broadcasting.” eays Crosley. “Radio broadcasting today is like a modem Tower of Babel,” he adds. “There are already twice as .many broadcasting stations as there should be for the number of wave channels available. Wave lengths are now assigned so closely to one another that the interference Is ruinous to radio reception on certain waves.” A Solution Asa solution to this situation. Crosley suggests the recognition of priority rights to pioneer broadcasting stations and the division of new comers and smaller stations into other classes. “The Department of Commerce Should have the necessary authority to refuse to issue licenses to new stations unless a wave length is available through one of the older broadcasters giving up a wave length,” is Crosley's plan. “There should be a waiting list,” he continues, “and the number of active broadcasters should be limited to the number of wave channels available for good service. “There should be a readjustment of wave channels. Pioneer broadcasters should be given the pref-

Best Station of 1924

".......... ...i

Bartholomew Moll sari. San Francisco amateur, Is winner of the Hoover Cup for 1924, for owning .he best amateur radio station in the country In which most of the construction Is the owner’s handiwork. His station is 6-AWT,

erence. providing their service and equipment is such as to justify such preference. Otassm Suggested “Broadcasting stations should be divided Into definite classes. The first five requisites of the high-class stations should be—priority, equipment, service, power, and capital invested. “Continued inspections, analyses, and requirements for the first class stations should be maintained. Failure to keep up with the rapidly advancing art of broadcasting should relegate obsolete stations into lower classes. “There should be several classes of stations, graded on the basis of these five points. First-class station a should not be asked to divide time; second-class stations should divide time two ways. Lower-class stations should have the use of the air to an even more limited degree.” RADIOGRAMS England has 2Jj 00,000 “radio pirates.” There is $9,000,000 In salaries to be spent each year in the United States for radio engineers. Scotland Yard, the world-famous headquarters of liondon's police, has seven automobiles fitted with radio, which are in constant doily use. Lehigh University, at Bethlehem, Penn., will erect a radio station at a cost of $15,000. The station will be known as WBLU, the B standing for Bethlehem, and the LU for Lehigh University. Never Remove Caps Never remove the caps from headphones. This impairs the efficiency of the units for the following reasons: When the phones are tested in the factory the receiver caps are tightened until pressure upon the diaphragm is just right. This test is made with delicate instruments.

CABINETS FROM LATVIA Baltic I-and Sends Radio Supplkw to America B\ Lnilrd Pm WASHINGTON. March 26.—1 tis almost unbelievable but thousands of radio cabinets are shipped from Latvia to the United States at the present time according to a report by Commercial Attache C. J. Mayers of Riga, to the Lumber Division of the Department of Commerce. These cabinets are shipped unfinished in knockdown condition to the United States, where they are assembled and The radio cabinets are made by school boys In the Technical and Industrial School at Riga, who are reported to have shipped several thousand sets last year and expecting to Increase the shipments to America to several million sets in 1925. PATENTS ON INCREASE 2,247 Reported Pending in Federal Office. Pu Timet Special WASHINGTON, March 19 —Ever since radio first gave inventors something new to work with, the lists of application for patents in the department of radiant energy and wave transmission of the Patent Office have grown tremendously. According to the Gazzette just issued by the Patent Office the number of patents pending in this section numbers 2.247, more than in any other section. Despite the ageing of radio and the number of patents already granted, there has been no falling off in the submission of new ideas.

CONCERNING CONDENSER Designed to Have I-arge Capacity In Small Space for Receiving. A condenser in a receiving set la designed to have- a large capacity in a small space. It consists essentially of metal plates which are insulated from each other by a dielectric or insulating material. It Is used in a radio-frequency circuit to tune an Inductive coil to a certain wave length, and is known in this connection as a variable condenser. It la used also to stop the flow of direct current and pass alternating current, and in this connection its capacity Is fixed, and It is known as a by-pass condenser. OSTMAN - WINS AGAIN Hoover Cup Holder Builds Besi Fifty-Watt Transnatter. Ted Ostman. known In the “Ham radio” world as SOM and holder of the Hoover cup for the best lowwave transmitting station in America, won another first prize at the fifth annual radio show, Hotel Pennsylvania, New York. Mr. Ostman wins this time for building the -best fifty-watt transmitter. Ted enjoys the distinction of being the first amateur to pick up a Macmillan message when the explorer was en route to the frozen North two years ago. " Keep Aerial From Wires In erecting an outdoor aerial it is important to keep the wire well away from other wires carrying current. It Ls dangerous to attach an aerial to a pole on which lightning transformers are mounted, or to run it over or under electric wires. For Insulating Rubber tubing can be used in place of spaghetti for experimental work.
