These . include the weekly Halsey-Stuart hour, the National Broadcasting and Concert Bureau Hour, the Seiberling Singers, the Hoover Sen- tinels and Buck and Wing, a comic sketch of the trials and tribulations of a “small time” vaudeville team. Special Memorial Program. A special Memorial day program has | been arranged by the Sontinels. Wi Jessica Dragonette as the soloist, th: orchestra will be assisted by the regular | quartet. “Pale Moon.” and the “Lit‘le Gray Home in the West" will be Miss Dragonette’s contributions. The orches- tral numbers include “Dream of the Big Parade,” “War Memories” and the | “American Patrol.” In the Seiberling program, Frank Black, composer-pianist, will play his own “Improvisations” as a piano solo. ‘There also will be a solo, “I'm Tiefen Kellar,” by Wilfred Glenn, bass, besides | the usual instrumental and orchestral features. Further financial advice in the realm of investment securities will be broad- cast in the Halsey-Stuart hour. The musical background for this feature will be provided by a novelty orchestra. Clyde Fitch's four-act drama, “Nathan Hale,” which was first produced in 1899 with Nat C. Goodwin and Maxine Elliott in the leading roles, is announced as the concert bureau offering. The drama is built on historical facts and in a previous radio presentation proved to be admirably adapted for the micro- phone. | Variety of Features. Aside from the Arlington exercis WMAL has scheduled a variety of holi. day features in addition to a eroup of the regular Columbia Broadcasting Sys- tem presentations. An hour’s program by the Columbians and the Rollickers, and another true detective story are among the Columbia offerings. The latter will concern the events leading up to the trapping of one of Canada’s greatest dealers in drugs. “Flashes from The Evening Star” a daily news review by Ralph McCabe, will open WMAL's evening program at 6 o'clock. A talk prepared by the Sclence Service on “The Tree as a Record of Anclent Climates” will fol- Jow. ‘The subsequent features range from a joint recital by Violet Warren Plerson, reader, and Dorothy Sherman Pilerson, soprano, to a concert by the Belle Haven Entertainers. ‘WOL's m this evening contains its regular features. Among them will be a special presentation by Billy Phelps, of the National Theater Players, and impersonations by Florence Jane Adams. i A Memorial day address by Represent- ative Strong of Kansas will be broad- cast tonight by WJSV. The musical portion of the program will be furnished principally by the Columbia Trio, the Hawalian Melody Boys and Howard Jones, baritone. . TROUBLE FORESEEN FOR WORLD RADIO Capt. Hooper of U. 8. Navy Points Out Interference Is Inevitable, ‘The newest of the radio communica- tion highways—the high-frequency band —is crammed full and the inevitable sftermath will be interference. Every new transmitter that takes the air from now on must squeeze in between operating circuits and with it cause dis- tortion of the signal on the neighboring channels. Although not serious today the interference situation in the high frequencies, used for transoceanic and other communications, is almost certain to take its turn for the worse. It will be & repetition, on an international scale, of what has happened to broad- casting in the United States—unless it is curbed now by international agree- ment. In broadcasting the mistake was made and 8o great was the congestion that reception was almost deplorable for more than a year and was rectified, to a certain extent, only after the sweeping reallocation of stations last November. Recognizes Seriousness. Bespeaking the seriousness of the in- ternational situation is an order just issued to the naval communications service by Capt. 5. C. Hooper, He points out that radio transmitters in use in the world are increasing rapidly in number, and that, consequently, in- terference is increasing. “As frequencies are now assigned, there are steps which can and must be taken to decrease radio interference,” e states. “Frequency stability of trans- mitters must be improved. Power out- put must be the minimum that will suffice for required communications. Transmitters must be kept accurately on assigned frequency by frequent checking of frequencies, using the best | obtainable frequency measuring appa- ratus. In some instances frequencies must be shifted or traded, or definite times or_operation agreed to.” Capt. Hooper is doing his utmost to keep conditions tranquil in the vital international communcations channels. He foresees an interference situation that may result in international arbi- tration, which perhaps will bring abont the assignment to each nation of blocks of frequencies in several frequency re- gions 50 as to centralize each nation’s holdings and preclude internation i terference. Navy Utilizes Channels. 1In so far as the Navy was concerned. | he says. this state of aflairs was recog- nized when the present naval frequen assignments were being made. A very thorough study was made and the Navy requested and obtained only the mini- mum number of frequencies to meet naval needs,” he points out. Under the Navy's present policy of roperly utilizing assigned frequencies o Rull capacity, Capt. Hooper expects that the Navy “will be able to keep as many frequencies as are now assigned” to it. Although he does not actually say so, he expects an international bat- | tle at the world-wide conference to be | held at The Hague in September re- apecting allocation and use of trans- oceanic frequencies. Hence, v should be able to keep what it being able to justify each fre- | assignment by proper and full | use. Even now governmental advisory com- mittees for The Hague conference are he says, | ver. ndianapolis Speedway races.

One of the most attractive sights just now in the parks of the National Capi- tal is the rose garden in West Potomac Park between the Highway Bridge and the railroad bridge, exhibiting thou- sands of buds and blooms, During the next month this rose garden, the entrance to which is nearly opposite the tourist camp, will be in the height of its glory. It is expected by the office of Public Buildings and Public Parks that some 10,000 visiters will view the gorgeous display of roses. Charles Henlock, chief of the horti- cultural division of the office, has charge of the rose garden under direc- tion of Lieut. Col. U. 8. Grant, 3d. Established in 1920, the garden is officially known as the Potomac Park Rose Garden, and from this area, in which a nursery is established, Col. Grant's force replenishes the stock of Toses for the far-flung parts of the city. There are 38 beds, each 12 feet by 60 feet, and a grass plot of similar dimensions between each bed. There are between 4,600 and 5000 rose- bushes there. The nine varieties of 0ss represented are Red Radiant, Pink Radiant, Ophelia, White Killarney, Madame Butterfly, Columbia, American Legion, Pilgrim and Mrs. Coolidge. | s O hain?

A cheap and simple “wave coil” a tuning device that eliminates the blan- keting effects often felt over the dials of ordinary radio receiving sets and also akes possible multiplex reception via a single antenna on the roof of an apartment house, has been perfected by Maj. William R. Blair, chief engi- neer of the Army Signal Corps, and Dr. Louis Cohen, famous radio inventer, at- tached to the Army Signal Corps as civilian consulting engineer and a pro- fessor of George Washington Univer- sity. Patents covering new phases of the invention are pending, but its develop- ment represents a continuation of work on resonance wave coils started by Dr. Cohen in the Army laboratories about eight yegrs ago in collaboration with Col. J. O. Mauborgne, former chief en- gineer of the Signal Corps, and Capt. Guy Hill, Signal Corps officer, now tem- porarly detailed to the Federal Radio Commission. The coil is an old invention, but the tuning method is new. The coil was first used in transmitting and receiv- ing to eliminate aerials, itself acting as an antenn | The invention, as recently demon- | at” the Bureau of Standards before | members of the Institute of Radio Engineers, involes a new principie by which results that were hitherto major problems of radio can be | attained. Its greatest possibilities are | seen in' its application to ordina | radio receiving sets. It consists simpl of a coil with a metal plate. to any radio receiver, it greatly intensi- !fles selectivity. Applied to the tran: | mission of radio signals, it completely | eliminates harmonics. . The most important and popular ap- plication of the device is expected to be |in the manufacture of broadcast re- ceivers and in the improvement of qual- ity reception on receivers already in homes, for it may be made part of the set or installed as an accessory. The | inventors have as yet taken no steps | toward its commercial exploitation, al- though they have the right to do so, despite their governmental affillations. Dr. Cohen has demonstrated that the “wave coil” will'bring in a chosen sta- tion at‘a particular point on the dial free from the blanketing effects some- times caused by other stations on adja cent wave lengths. For example. he is able within a distance of one mile from station WRC, Washington, which is operating on 950 kilocyeles, to tune-in the Canadian station onerating on the adjacent Canadian channel of 960 kilo- cycles. Ordinarily a receiver in such proxim- ity, especiaily if the station employs an appreciable amount of power, can sel- dom pick up programs on channels so near. Dial points next to a station coming in loudly are either covered by that station’s programs or are dead. This result can be accomplished all along the dial. The efficiency the coil adds to the average receiving set is parent to almost any listener. Re- gardless of any station power, its pro- grams can be restricted to its normal channel and progra from oth 0\\\\\\“\‘\‘\\\\&\\\\\\ k4 Attached | tions received. width of the 10-kilocycle band; for that many frequencies are needed for good | modulation of vocal or instrumental programs. It does, however, eliminate interferenuce from ' stations on nearby frequencies and to some extent reduces static. Ends Duplicate Antenna. The multiplex reccption on a_ single antenna that it makes possible will have great advantages. At present it |1s generally necessary to have separate antenna for each receiving set. except where highly expensive central installa- tions are made. Thus many apartment houses now have their roofs strung with jungles of wires, but this sys- m provides for only one large antenna with the lead-in wires to each apart- ment. The respective apartments may be | equipped with the “coil wave" or the set owner cal 1stall it on his own set He is then a to tune for any station he desires, despite what his neighbor in another apartment may be receiving off the same antanna. ‘The same method of tuning is ahEIZPd PSS S TIRRRRRRRRRRRRRRRRRNS Radio Service Phone Adams 3803 18th & Col.
