Donald M. MacMillan home from the Arctic, had not been in operation more than 24 hours be- fere mysterious changes became no- ticeable in the wave length of the transmitter. When the sending set was tuned to a wave length of 165 meters there would be a variation of eight meters in a few hours; when it was tuned to the short wave of 80 meters there Would be a varfation of about three meters in approximately the same Space of time. This phenomenon con- tinued, despite all efforts to keep the oscillator sharply tuned, and ama- feurs with whom the station was in communication persistently asked Why the sending wave was being changed. The' adjustments of the station were gone over very carefully sev- eral times and a wavemeter was em- ployed frequently to check the oscil- Jations. Finally it occurred to Traf- fice Manager Schnell that, since the antenna and counterpoise had been Suspended from the dock over the wa- ter, the tide might have something to th it. 3 hmeupon he decided to take his readings with the wavemeter at the ebb and flow of the tide and compare them. He discovered that in every case the wavelength increased with the rise of the tide and decreased With the fall. Now in order to keep the transmitter at a constant wave, he makes regular adjustments to cor- respond as far as possible with the tide's movements. He declared the tide changed the capacity of the sta- tion’s counterpoise. o ——————————————————— —— and is owned and operated by the Third Avenue Railway Company.

THE MIRACLE CLEANER 1 WASHINGTON, MARK URGES RADIOS FOR LOCAL SHUT-INS Broadcasts to Fans Plea for In- stalling Sets in Hospitals and Charitable Institutions. ‘Washington radio fans were urged by LeRoy Mark, in a speech broadcast last night from WCAP, to put their heads together and devise some scheme to raise $34,000—the amount needed to insure the installation of radio receiv- ing apparatus, in every hospital, chari- table institution and orphan asylum in the Nation's Capital. Mr. Mark has given the broadcast listeners two weeks in which to work out the idea. Meantime, he wants those financially able to continue to send in contribu- tions to the Washington hospital radio fund. The concert given at the American League Ball Park Sunday afternoon, September 14, by the combined Army, Navy and Marine Bands, raised a lit- tle more than $6,000 of the $40,000 estimated as the cost of installing radio sets in the institutions, Mr. Mark told the radio audience. The ball park gate receipts were $805. The collection at the park amounted to $999.09. Added to the money recelved from the sale of tickets and voluntary contributions, the total funds stands at $6,247.76. “We must have $34,000 more and we are going to get it,” said Mr. Mark “And remember there is no overhead. We are striving to complete the won- derful work without any compensa- tion other than the feeling that it is a good work, well done.” Mr. Mark thanked the band leaders and the numerous others who con- tributed their services to the massed band concert.

FIFTEEN MINUTES OF RADIO EACH DAY BY JOSEPH CALCATERRA, Radio Editor of Popular Science Monthly Al Rights Beserved. Reproduction Prohibited. How to Build the Lloyd C. Greene Concert Selector Receiver. Part I. Up to within a short time ago the three-tube regenerative receiver stood easily head and shoulders above any other type of receiver in point of popularity with the great army of radio fans who wanted to get the programs from the many broadcasting stations located within 500 miles of them, and get them clearly enough and loudly enough to hear them plainly on a loud speaker. The regenerative set has many good points and its popularity has been deserved. Factors, however, have now entered the lists which make it ad- visable to limit in some way the use of the regenerative receiver with the troublesome radiation problem, which it introduces, and many proposals have been made and suggestions brought forward which have for their object the elimination of this trouble- some feature of the regenerative re- ceiver. From the first it was generally recognized that the use of a stage of radio frequency amplification ahead of the detector and the sacrifice of the regenerative feature would be the best solution to a problem which was growing more and more acute. Many of tho most prominent radio experts In the country tackled the problem, with the result that a num- ber of receivers which eliminated the radiation nuisance at a slightly greater cost for the receiver, but with no sacrifice of efficiency, came to light Develops Geod Substitute, As was foreseen, the best substi- tute for the highly eflicient regenera- tive receiver proved to be the four- tube receiver, using a stage of radio frequency amplification, a_detector and two stages of audio frequency amplification Of the many receivers of this type, the Greene concert selector, designed by Llovd C. Greene of Boston, Mass., radio editor of the Boston Gfobe, has acclaimed as one of the very best of its kind by radio fans throughout the country and 16 a‘popu- lar favorite throughout New Eng- | land. In tackling the problem Mr. Greene kept in mind not only the matter of eliminating the radiation nuisance, but also of simplifying the construc- tion of the receiver so it could be built without trouble by any new- comer in the radio game. In the first place, he designed a special type of tuning device which entirely eliminates the use of induc- tance or tap switches, thereby con- siderably reducing the construction problem of the average fan who finds the use of inductance switches and taps a nuisance, to say the least. The tuning device makes use of a primary circuit tunable on the vario- meter principle and properly coupled inductively with the secondary coil. The secondary coil is tuned by a variable condenser across it. The antenna tuning element con- sists of two coils of about four turns each, one coil on the outside half of each stator form and two rotor coils of the same number of turns, one coil on each half of the rotor form. The secondary coil consists of two coils, one on each inside half of the stator forms. Coil Connections Described. One end of the outside stator coil L1 is connected with the aerial, while the other end is connected in series with one of the rotor coils L2. The other coil, L3, is connected in series between rotor coil L2 and other out- side stator coil Li. The other end of stator coil L4 is connected with the ground. The two inside stator coils are connected in series to form the secondary winding. The few turns used on the outside stator winding of the antenna vario- meter makes the electrostatic coup- ling between the antenna and grid circuit negligible. The electromag- netic coupling between the antenna and grid circuit can be varied from almost zero to. between 20 per cent This fact is of considerable im- portance in determining the ability of receiver to give maximum volume with greatest selectivity.
