A military company is expected to sound taps as final salute to the dead. The First Air Glider. From Popular Mechanics Magasize. Short glides in.the air were made as early as the reign of King Harold of Engiand by a monk named Elimer, who, after several successful flights, jumped from a lofty tower with wings strapped to his body. He glided for a furlong or more, when, striking a cross air current, or “air pocket,” he fell to the ground, reaking both legs. He attributed the accident to his neglect “to fit on a tail” “Coffee ments, with music by the orchestra THE SUNDAY STAR, WASHINGTON, D. C.

Radlo recelving sets are now considered by architects as fixtures, and the detalls of wirlng. battery space and antenna Installa- tlon are being written into specifica- tions. One of the first radio homes—that iss with facllities for radio bullt into the house—is that of L. 1. Whitte- more, seeretary of the governmental interdepartment radio advisory com. mittee. Before comstruction was be- gun Mr. Whittemore explained his ra- dio requirements to the architect, who included In the plans all radlo facil- itles required by this engineer and enthusiast. A non-metallic conduit plerces the study wall for a lead-in wire; an- other goes below to a special space in_the cellar reserved for the bat- teries, while a third Is for the ground lead. ~ Another plece of conduit pipe will carry leads from the set to a floor ar “wall socket in the living room, where a loud speaker may be instailed if destired. Besides aerial on the house top, the owner plans to install two single, vertical loops in the north and west wall spaces of his study, the wires termi- nating in special sockets for an an- tenna plug connected with his set. This feature will give him certain di- rectional selectivity, as he can use, at will, the loop facing east and west or one ‘at 90 degrees to it. “Hams» Improve Recelvers. The fourth series of transatlantic tests of the American Radio Relay | League between December and January 10 will be a receivin; as far as American and Canadian amateurs are aoncerned. They will keep their transmitters. silent during the entire period listening for signals ifrom European operator: Belleving that thelr skill in trams- mitting has been tried and proven, amateurs on this continent are now golng to show the Kuropean radio men the courtesy of allowing them to do the sending, while their own sets and ears are sharpened and tuned o _catch the incoming signals. During the first three transatlantic tests North American amateurs were determined to get their signals across the water. Transmission was the big thing and meant everything to them. Sven last year when signals from United States transmitters were hurled across the ocean by the hun- dred, there was only a mild Interest in the recelving end. This was a great disappointment to the French and_British hams. % With the conditions for the present tests changed and the motives prac- tically rversed everything depends on the receiving, and the time previously used by each operator in gettiug his entire apparatus into trim, will now be given almost wholly to the im- provement of the receiving circuit. This opens the way for the freg-for- all-two-way tests, which immediately follow the last day of the transat- lantics. The program that has now been ar- ranged by F. H. Schnell, traffic man- ager of the American Radlo Relay League, calls for transmission by the British amateur and French oper- ators on alternate nights between 8 and 1 o'clock, eastern standard time, with the latter starting on Decem- ber 22 i Another feature of the tests is the Inrzar by prominent manufacturers of thousands of dollars' worth of radio apparatus for prizes, including a $1,100 transmitter. In previous years this season found the American ham going over everyf, detall of his transmitter, devising new ways of crowding stray watts into his set to Incre: his range. Now the same careful attention i3 being glven to the receiver, while the CW sending set atands idlo with the aloof dignity of accomplishment. Tt is no novelty for the relaving amateur to rebuild his recelver and it is directly in line with the present movement calling for the installation |of the superheterodyne, o another {of the new types of receiving cir- jcutts that are fast gaining in popu- arity. This means a®@radical a-change as it was for the amateur to revert from the old thunder spark set to the smooth-toned CW In transmis- sion. The complete failure of the first transatlantic amateur tests in Feb- ruary, 1921, only acted as an Incen- tive for those that followed. Tra oceanic amateur radio loomed up as a tremendous achievement. The next year the experiment was considered worthy of sending an American ama- teur, Paul Godley, to Ardrossan, Scot- land, to listen. There in a Mfishing village some twenty miles to the west of Glasgow, Godley heard neary thirty stations and one complete message. The Job of getting across was finished to all purposes; it had been proved ama- feurs could reach over the broad At- lantic on low power. The business of organizing the third transatlantics was by way of demonstrating that transoceanic ama- “|teur radio could become a common d was well within the realm g;lnt e“prmlaL The signals went ST, 20 e TS The fnai total 3 nd wi e s us. more than 300 sta- 1anded. ";’n‘th:a'd‘we!l iound" tests a total of about twenty American amateurs heard European amateur signals, pri- marily from three stations, 'Fr:n:'?h SAB, British 5WS and British 2FZ. American hams plan now to surpass all receiving records. Seven Standard Stations. Sev radio statlons have been n:r:;;nhy the bureau of standards as maintaining sufficlently constant transmission frequencies to serve &s standards for calibrating wave meters and radio receiving apparatus. Two, KDKA and WGY, are broadcasters. The stations, located in Maseachu- etts, New York, New Jersey, Penn- sylvania and Maryland, include one naval station, four radio corporatipns, one General Electric and one West- inghouse station. The ‘Tuckerton station of the R. C. A. leads the seven In accuracy, deviating only one-tenth of & per cent In thirty-six tests of its assigned frequency. All the other stations, however, are not deviating on an average of more than 3 per cent, and should serve as fairly ac- curate measures of frequencies. The seven stations are: WQL, Long Island, N. Y.; NSS., Annapolis, Md.; WQK, Long Island, N. Y.; WGG, Tuckerton, N. J.; WSO, Marion, Mass. ; WGY, Schenectady, N. Y., and KDKA, rgh. Plg:!‘:l‘:nsnuns on the standard fre- quency _situation, the bureau of standards says: “If every radio trans- mitting station maintained exactly the wave frequency assigned to it there would be available a standard frequency wave every time any sta- CFor 19 years the best, in the world for A MURDOCK HEADPHONES AT ALL RADIO DEALERS ‘Wi J.

However, at present this is the case only with cer- tain stations, and because it s & matter of difficulty to maintain ex- actly fhe assigned frequency, and also because this s of great im portance, the bureau has been collec ing some interesting data on the sub. ject. A3 a result of these measure ments, it is possible to give out in- formation, from time to time, on st: tlons which malntain a suffictenc, accuracy to be useful as frequenc, standards. Several stations, which use special means for malntaining constant frequency, have very nearly attained the goal of remalning within two kilocycles of the assigned fre- quency, as recommended by the second 'national radio conference.” Transmissions from seven-stations may be ysed in standardizing ap- paratus, by the methods given in bureau of standaras letter circular 92, “Radio signals of, standard frequency and their utilization.” Crystal Set Interesting. The crystal detectors ars the simplest of all radio detectors used at the present time. Unlike the vacuum tube, it does not, in most fixtures for erecting an |eases, require a local battery for its operation, and the initlal cost is practically the last cost. The crystals are inexpensive, easily obtained, and can easily be replaced with little trouble, should the old ones become inoperative or dirty. /Their disad- vantages are threefold. They are| éritlead to adjust; they are not as sensitiVe as vacuum tubes, and, thirdly, they cannot be made to oscillate for the reception of amateur continuous wave signals. Essentially the crystal detector, sometimes known as a mineral tector, consists of a crystal upon which' a contact of copper or steel wire {s made. It Is this contact that permits the reception of signals, inasmuch as this contact 13 a rectifier of the radlo frequency currents. Crystal detectors consist In the com: merclal form of a base, a metal cup n which the crystal i3 mounted, a wire contact, Known as the cat whisker, a holder for the wire, and binding posts for convenient con- nectfons. he crystals used most commonly at the present are: Galena, radiocite, silicon, carborundum, and bornite, in the order named. The first two require a light copper or phosphor bronze contact, while the rest work better with a heavier steel, needlg-point cont. The radio frequency energy in the receiving set, before it reaches the detector, 18 a weak alternating cur- rent, similar to the house lighting current, but where the house laghting current alternates its polarity 120 times per second, this radlo frequenc. current alternates its polarity 1,000.- 000 times (or more) per second, namely, where the house lghting current has a frequency of sixty cles, the radlo frequency currents have a frequency of 500,000 cycles par second. A currénmof this frequency cannot be heard for several reasons. When one of the groups of alternations acts on the telephone receiver it causes no motion of the diaphragm, because each variation of the current in one direction is followed by the current flowing in the opposite direction, so that the telephone diaphragm has not enough time to start moving and resulting effect 1s no motion at all, Something that allows the current to flow through it in one direction and stops the current from flowing in the opposite direction is needed in the circuit, to actuate the digphragm. The detector does this. At the cdntact between the crystal nd the cat whisker, current can flow through In one diréction, but mot in the other. Such oscillations pass through the detector, which sup- presses half of these oscillations. This current is still vibrating much 100 fast for the telephone diaphragm ta follow, but the successive impulses of current flow through the telephone receiver, and the impulses In any one group are all in the same directton, 50 that their effects add and produce a motion of the diaphragm.

Four new Class A broadcasting statlons were licensed last week by the Department of Commerce as fol- lows: KFLU, San Benito, Tex.; KFLV, Rockford, Til.: KFLW, Missoula, Mont,, and WWAF, Camden, N. J. WHAM at Rochester, N. Y, was transferred from class C to class A, . through the windings Smoke Causes Interferemee. Radlo fans have complained about practically every kind of interfer- ence, but lately a new form of elec- trical emissions making local ‘radio reception difficult has been called to the attention »of the radio of- fictals of the Department of Com- merce. Complaints against plants using the Cottrell electrical emoke precipitation system have come from fans An Pennsylvania, Arizona and Mgntana. Several letters received state that the factories using this high-fr. quency method of consuming and purifying smoke, cause electrical di turbances similar to radio waves, which interfere with regular radic messages and broadcasting within a radius of about 20 miles. A very noticeable hum fs sent out into the atmosphere by the precipitation. There is no law against interference from this sort of inadvertent trans- misston, and the Department of Com- merce has merely called the atten- tion of the offending plants to the disturbance they were creating. Steps taken by « company to pre- verit the hum in thelr Arizona plant have been satisfactory, it is said, and other plant owners have expressed a willingness to clear the air for the radlo fans. A method of groundin or shielding the electric equipment is understood to be under Investigation. Literally the plants ysing this form of smoke consumer aré benefittin, all their territory since. they are clearing the air “of injurfons and i polsonous gasses, soot, and other ob- Jjectionable matter, even if they do creaté a slight electric discharge sim- ilar to the hum of a motor generator. Call for Life Boats. Two of the Leviathan's life boats, both ten-knot motor boats, have radio transmitting and receiving sets and ¢alls of their own. Life boat No. 67 is WSNA In radlo talk, and No. 68 is WSNB. The Leviathan's own call is WSN, her two tenders carrying an additional letter. This is a new departure in Amerl. can shipping, planned as an _addi- tional sea safety precaution. If the Leviathan's radlo apparatus should get out of order or she should be sunk her two motor boats could com- municate with rellef ships, within about fifty miles, guiding them to the scene. Each of these radio-equipped |eraft carries a spark set and _one K. W. gas engine generator. Th communicate on wave lengths of 300 and 600 meters. Radio Jumps Mountals. Radio is being used successfully in India to send messages over & moun- tain 00 feet in height. Previously considerable difficulty’ was found in wire communication, due to heavy snowdrifts and storms which severed the lines. This achievement has been effected between the cities of Srinagar and Jammu, in Kashmir. Other in- stallations have been effected or are planned in Bhopal, Gwallor, Hydera- Bad and Rejkot by Marconi engineers, Trade Commissioner Spofferd reports to the United States government from Calcutta.
