Saturday Afternoo In Scheduie n Band Music for Broadcasting Army, Navy and Marine Concerts Now Concentrated at Sylvan Theater and Telephoned to New York and Radioed Throughout Country. Saturday afternoon at the Eilipse. the Capitol and the White House lawn by the Army and the Marine bands were discontinued this season and, instead. held at the Sylvan Theater, where the programs are sent by telephone to New York to be broadcast over the Nation. This is the answer, according to ex planations made by the captains of the military bands, which provide the Capital City with band music. to the queries which have come to The Star regarding the Saturday concerts. Instead of the Saturday afternoon concerts, which the large portion of the Washington public was denied by band concerts the change of program for the bene- | fit of the millions of the Eastern part of the country, concerts were sched- | uled for Saturday evening and Thursday evening at the Ellipse. Army Band Schedule. Capt. WiNam J. Stannard Army Band gave the usual s of the concerts of his band as: Mon day, at 7:30 o'clock, at one of the public parks assigned by Lieut. Col. Clarence O. Sherrill; - Tuesday, at 6:30 o'clock, at Walter Reed Hospital Wednesday, alternating with _the Navy Band in programs at the Navy Barracks at 6:30 o'clock: Thursday, at the Ellipse, 5 o'clock, on every other week, alternating with the = sizgnment at Mount Alto Hospital, where concérts are given at 7 o'clock: Friday, at the Washington Barracks, 650 o'clock, and, Saturday, every other week at Sylvan Theater, at 7:45 o'clock.

Craven. 1712 Corcoran street. She isks: “Is there some deep, dark rea son, or s it merely the human pro- pensity of wanting to improve what is perfectory?” “The Saturday afternoon concerts ave been an outstanding and exceed- ingly plensant feature of Washing- tons’ Summer life for many years, | which T have enjoyed to the full ever since they were resumed after the war.” Miss Craven adds. “This letter is sent with the hope that it may perhaps reach the eyes and perhaps the hearts of those in charge of the concerts. It is also hoped that if there are others who feel as the writer does, they may be moved to voice thelr own apprecta- tion of the concerts and thelr regret at the discontinuance on Saturday afternoons.

Besides, why fool with the acrial? Some of these fellows who get DX don't use any outside wiring at all.” 1 suggested that maybe he wouldn't | have to get up on the roof. A lot of trouble is due to the layout of the lead-in, which is a part of the aerial so far as intercepting the radio waves is concerned. This proved to be the answer to his problem. Before he knew it he was on the roof and studying the situation throughout. The discoveries he made are well worth passing along. The first thing he did was to note that the ground wire ran too close to the lead-in from the aerial. The wires not only ran close together but ex- actly parallel. Smith had had enough experience with condensers to know that when the wires for the two op- posed currents run so close together there is a capacity action between them. Much of the energy picked up over the aerial lead-in passes directly to the ground without so much as coming in to the set. In other words, he was wasting as much reception as If he had several poor connections along the line. In putting up the aerlal originally he had taken great pains to see that the lead- in did not touch the building or rub agzainst a cornice, yet here he had gone all these months with a very serious form of energy loss right close to the set. He became Interested to a point where he began to experiment a little with the flat top of sthe aerfal itself. Here he found it of value to wa down the avenue and to see how his neighbors ran their aerials. There were all kinds and varieties and just about as many error One of the most noticeable, and one that is a constant trouble maker, was the imperfect T aerfal. In a true T aerial the lead-in taken off from the center of the wire or wires constituting the aerial proper. If this is the type preferred, it is necessary to have the halves ex- actly equal, because otherwise there can be no sharp tuning of the set. The shorter end will be trying to vi- brate at a higher frequency than the other. This naturally interferes with the practice of splitting interfering stations and may account for the fail- ure to get distant polnts when others do it with ease. He found the L aerial the most prevalent type. This is an aerial with the lead-in taken from one end This should, of course, end if the aerial is not level. observations, however, Smith found some of his neighbors bringing down two lead-ins, one from each end of the flat top of the aerial, and he asked is Local Radio Entertainment Sunday, July 5, 1925.

It’s just like the way some people keep the aerfals close to the roof because they have been told that the farther up they go the more static they get. They do not realize that the higher fhey go the better they can receive, staflic or no static. And you know that static is often absent “Another thing I notice,” Smith con cluded, “is that most people point their aerfals in the direction of sta- tions they want to hear most. just as I do.

Inquiries from foreign countries as |to American-made radio apparatus and equipment were received by the Department of Commerce from Africa, England and the Netherlands, during the past week. The prospective African purchasers were interested in long-range receiving sets; English fans desire radio sets, parts and tubes of the best quality; while a Nether- lands manufacturer is anxious to se- cure transformer sheets. Consular advices also point out that while broadcast reception has not yet reached the Amoy district of China, a good demonstration would probably work as an “open sesame” in that ter ritory.

The Ku Klux Klan is among the organizations that will seek broad- casting licenses from the Department of Commerce when and if additional wave bands are provided this Fall, it is understood here. It “was reported about a year ago that extensive plans for a system of stations throughout the country were under consideration by the klan, but the difficulty of obtaining wave lengths caused temporary abandon- ment of the project. More recently the matter has again come before the klan, with several of the higher of- ficlals strongly supporting it. Among the States suggested as possible homes for the klan stations are New Jersey, Indiana, Texas and several other of the Southern common: wealths. The klan chain of stations, if the plans for its installation are carried out, would be unique in the United States broadcasting field. Although several fraternal, religious and polit ical organizations maintain a single broadcasting plant at their head quarters, no body of this nature has ever considered a group of stations that would cover all or a section of the country. The expense of such a group of plants, together with the cost of maintenance and operation, s ordi narily held to be prohibitive, and many klansmen, supporting the gen eral movement to get on the air, are expected to urfe that a single station be erected to serve the na- tional klan organization TRINKLE WILL SPEAK AT MANASSAS PICNIC Anniversary of Civil War Battle to Be Observed July 21 on Henry Hill Heights. Representative William D. Unshaw of Georgia, chairman of the advisory board of the Manassas Battlefield Con- federate Park, announced today that an all-day picnic will be held on Henry Hill Heights on July 21, the anni versary of the first battle of Manassas. The public is invited to attend. Each person attending is to take his own lunch. Gov. E. Lee Trinkle of Virginia will address the gathering. Other ad- |w dresses during the day are to include a description of troop movements, in cidents and positions during the first Manassas battle, July 21, 1861, and probably similar descriptions of the battle of August, 1862. Mrs. Beverly R. Tucker of Rich- mond, Mrs. Robert E. Lee of Washington, Mrs. Howard Fletch- er of Warrenton, Miss Lillian Utter- back_of Marshall, Mrs. C. W. Massie and Miss Virginia Henry of Harrison- burg are members of the sponsors committee. Rev. W. R. Everett, Marshall, Va., will serve as chaplain, assisted by local ministers. Claude N. Bennett, past president of the Southern Soclety: Wade H. Cooper, president of that organization; J. C. Ramey of Marshall, Va.; A. H. Jen: nings, historfan-in-chief, S. 'C. V., Lynchburg; J. Clovd Byars of Arling- ton, Va.; George M. Fletcher and Maj. R. 'A. McIntyre of Warrenton, Va., and Lloyd S. Everett of Falls Church, Va., are serving on the reception com mittee. C.J.

NEW YORK, July 4.—German methanol, whose importation is cut- ting in on the fleld of America's wood distillation industry, is danger- ous to life under some conditions, ac- cording to a_statement of Prof. Reid Hunt of the Medical School of Harvard University, as reported by the Ameri- can Chemical Society. Use of synthetic methanol as a beverage or as an adulterant *will be followed by the same disastrous effects to life and vision as have characterized such use of wood alco- hol,” this report indicated.

RADIO GOSSIP AND NEWS A survey of the fiscal year's activi- ties in broadcasting shows that 281 new stations went on the air, while 245 ceased brondcasting, resulting in a gain of 36 stations during the year. On July 1 there were 571 stations in operation, comprising 101 Bs, 468 As and 2 Cs. Compared with July 1 last year, there were 378 As, 56 Bs and 101 C stations. The Cs have either dropped out or been transferred to A and B status, untll but two remain on this, the original broadcast wave lengths of 360 meters. Due to a lack of wave lengths in the higher power or B band, four of the recently licensed stations are qualified as B's, but are on the lower wave lengths in the class A band. Increased power is the important de- velopment this past 12 months; there being 19 stations operating with power between 1,500 and 5,000 watts. Five of these stations are in the high-power class; WSAI, WLW, WOC, WCCO and WCED, all being 5-kilowatt stations. In compliance with governmental re- quirements and 8o as not to cause un- due interference locally, all these sta- tions authorized to transmit with 5 kilo- watts are located from 10 to 15 miles beyond the confines of large cities. WEAF 1is next in power, operating with 3,000 watts; WTAM uses 2,500 watts, while seven have 2,000 and four are using 1,500 watts. KDKA is the most powerful; it is listed under a special broadcasting license for ex- perimental purposes and may use as high as 10 kilowatts. Approximately 130 new stations are reported proposed or in course of con struction, among them 50 hope to se- | cure ciass B status, and 80 plan to op- erate as As. As far as congestion goes, it is practically as bad as it ever has been, even when there were 591 stations broadcasting; this is partly due to higher power. The fact that class A stations are seeking more pow: er will make it more difficult to suc- cessfully separate those shorter wave lengths, if many use the same chan- nels. As Secretary Hoover has pointed out, there are absolutely no more Class B wave lengths available, so newcom- ers in the field must take what they can get—A wave lengths, which are now getting scarce. The whole band assigned for broadcasting located be- tween 202.6 and 545.1 meters is practi- cally exhausted and it is probable that at the radio genference scheduled for September additional space on lower wave lengths will be sought, unless Hoover is convinced by the consensus of opinion that he should refuse to li- cense any more broadcasters. In that he will have to ask Congrt for au- thority which he now lacks. It would not be practical for him to refuse li-| censes to stations which can compl; with present regulations without legis- lative authority, for it would undoubt- edly be held as discriminatory. Obviously, if we are to have any more broadcasters in operation, the in- dustry, engineers and fans will have to aid in finding room for them on the alr. But in view of the opinion, held by many exponents of the art, that there are too many now, it is possible that the consensus of<opinion may in- dicate a desire to stop licensing sta- tions except in territory not served b; existing station: Bowdoin in Touch With Home. Amateur radio is already fulfilling its mission as the only link between the Navy MacMillan expedition to the far north and the homeland. Mem- ber stations of the American Radio League In_ Alabama, Illinois, New | York and Pennsylvania have already communicated with WNP, radio station of the Bowdoin, flagship of the expedition, and the valuable data on reception which is sent back through the air to John L. Reinartz, operator of the station, is expected to help clear up the difficuitis which beset the last MacMillan expedition. As soon as the observation work of the expedition gets under way the | dispatches of Donald B. MacMillan | to the National Geographic Society | are to be sent regularly to member stations of the American Radio Relay League in accordance with the plans perfected between Mr. Reinartz and officials of the league in this city.! These dispatches, it is hoped, will be handled by a large number of stations from coast to coast, and the problems of reception at this end will be largely cleared up by the constant tests now under way. | The present work of WNP is being | handled at about 40 meters and it is the intention of Mr. Reinartz to| shade downward until he reaches a ve length that gives the greatest| satisfaction in the continual daylight | which the expedition will soon en- counter. Reports from United States amateurs have been received at league headquarters here WNP began work June 17, the day the Peary sailed from Boston to join | the Bowdoin at Wiscasset, Me., and contact was made with two stations. J: W. Newman of Mobile, Ala., opera- ting station S5AOM, carried on con- versation with WNP for 45 minutes on a wave length of 40 meters. The same day, WNP, at Wiscasset, talked with E. H. Conklin of Evanston, IIL operating station 9DBF, using a wave length of 4212 meters. Complains of Harmonics. Rufus P. Turner, operator of ama- teur station 3LF, complains bitterly of the harmonic interference by class B croadcasting stations. In a letter to the radio editor of The Star, Turner write “A section of the April, 1923, amend- ment of the United States radio regu- lations reads: ‘Wave lengths between 280.2 and 545.1 meters are to be as- signed to broadcasting stations which shall become known as class B sta- tions, the transmitter used by this class station must be free from all harmonics and must be inductively coupled to the antenna circuit when ever possible.’ The law additionally | states that any failure to live up to the strict requirements of the class B stations will result in the forfeiture of the class B privilege and the re- licensing of the station to operate on wave lengths below 280.2 meters. Yet, at present, some of the lead- ing class B stations of the country have harmonics all the way down the scale to 40 meters, and consequently are causing a great deal of annoyance on the amateur wave bands. With a short-wave receiver, tuned to 80 meters, as indicated by a calibrated wavemeter, I was able to pick up a concert broadcast by one of these stations when the set was hooked to an antenna which has a fundamental of 42 and a fraction meters. The music disappeared at 75 meters but | came in again even louder than be- fore when the 60-meter adjustments 2119 18th St. N.W. specting the rights and works of the amateur, the law be enforced | Develops Underwater Communicati | Dr. H.
