" PLANSCONPLETED FOR RADID TESTS International Broadcasting Experiment to Begin_ : Tomorrow. Everything is set in America, Europe and other foreign lands for the international radio tests which will commenee tomorrow and con- tinue throughout the week up to and including - Sunday night, November 30, according to Arthur H. Lynch and Hugh S. Podock, who have made the broadcasting arrangements with sta- tions In North America and Europe, respectively. On each evening of the week from 10 to 11 o'clock, Eastern Standard time, North American stations will broadcast special programs for the benefit of European listeners, during which period European stations will remain silent. The North American broadcasters include 44 stations in Canada, practically all of the sta- tions in the United States, the four Mexican stations, those in Cuba and Porto Rico. Nine big radio broad- casting stations on the European continent will in turn’ open Inter- national Radio week at 11 o'clock Eastern Standard time, tomorrow night and broadcast special pro- xrams in several different languages for & period of one hour in an effort to reach the American listener-in Tuesday night the European program will be broadcast by stations of the British Broadcasting Co., which will alternate with the continental sta- tions throughout the remainder of the test week. Stations Are Listed. The following continental stations will be heard Monday, Wednesday, Friday and Saturday nights from 11 pm to 12 midnight, Eastern stand- ard time: Continental Stations.

Lee Chapter held its No- vember meeting at the Confederate Home. Chapter officers for the ensu- ing year were elected, the list being headed with the unanimous re-elec- tion of Mrs. Maud Howell Smith as president. Mrs. Smith has served the chapter well for the past vear, her chief object in the work being always the care, comfort and enter- talnment of the old veterans whose | ranks are 5o rapidly being thinned by death. Delegates and alternates for the District. division convention in December were eleéted. Also God- speed and a good time were tendered the delegates and alternates to the national convention who were just about to leave for this meeting in Savannah, Ga. furnish completely and maintain per- manently a room in the home for the use of veterans wishing to remain there avernight. The need for such provision was strongly urged by Mrs. Emmert, in charge of the home. She told the chapter how hard it very frequently was for her to ac- commodate old veterans from the suburbs or countyy who wished to remain in town after meetings or en- tertalnments at the home. A visit was pald the chapter by the division president, Mrs. Albion W. Tuck, to say good-by on the eve of her departure for the conventlon in Savannah. An entertainment with music, danc- ing and refreshments was arranged in honor of the veterans for the evening of December 1, and commit- tees to make uarrangements were named. The Hilary A. Herbert Chapter met Wednesday evening at the Con- federate Memorial Home, Mrs. Rose D. Mulcare, chapter president, pre- sided. Reports of officers were ap- proved. The work fer the Winter was outlined, and plans for a card party discussed. The election of of- ficers was held as follows: President, Mrs. Mary K. Nulle; first vice presi- dent, Mrs. “Rufus P. Clarke; second vice president, Mrs. Eugenia Z. Rol- lins; recording secretary, Mrs. Wil- liam F. McGee; corresponding secre- tary, Miss Ma; Bringhurst; treas- urer, Miss Mary E. Hungerford; regls- trar, Miss Nannie G. Hungerford; historian, Miss E. C. Gray; parlia- mentarlan, Mrs. Jamés Trimble custodian, Mrs. H. W. Kearney: chaplain, Mrs. Archibald Young. Mrs. Rufus Clarke spoke of the work accomplished by Mrs. Rose Mul- care, organizer and retiring presi- dent of the chapter. By unanimous vote Mrs. Mulcare was made honorary president for life as an expression of appreciation. ‘The Seuthern Cross Chapter met Monday night and elected the follow- ing officers for the year: President, Mrs. Thomas Carter; first vice presi- dent, Mrs. Thomas Ferguson; second vice president, Mrs. Harvey Ball; re- cording secretary, Miss Catherine Frederick; corresponding secretary, Miss Margarite Downs; treasurer, Mrs. Clarence Albaugh; parliamentarian, Miss Dora Balley; registrar, Mrs. Jane Ellot; historian, Mrs. Phillp Hill, and chaplain, Mrs. Effie Tancll. After the business meeting there was a social gathering and an informal reception to the new officers. This chapter is glving a series of card parties. The first one was held in the home of Mrs. Eliot and the next one will take place the evening of December 3 in the home of Mrs. Clarence Albaugh. GETS AWARD FOR FIRE. Philadelphia Company Allowed $339,089 by Cotrt. PHILADELPHIA, November 22.— A jury in the Federal district court today awarded the Philadelphia Stor: age Battery Company a verdict fa: $339,989.80 against the Air Reduction Company, Inc, as damages in con- nection with the destruction of sev- eral of its buildings in a fire which the battery company claimed was caused by an explosion of a defective manifold on an oxygen cylinder. The reduction’ company main:aiied that the explosion of the manifoid was due to careless and negligent op- eration of the oxygen cylinder by one of the battery company’s employes. —_— 2 Bdmonton, Albsrta, recently shipped 58 head of Adberty cattle to Japan = an experimest. The chapter voted to | work in establishing As part of it the Bureau of electrical standards, | Standards, has inereased the accuracy of radio-frequency- standards and measurements during the past fiscal year. Broadcasters, as well as other radio stations, were directly aided in keeping on their assigned wave lengths, which naturally aided the radio broadcast listeners In tuning and eliminated some interference. In the annual report, the radio sec- tion of the bureau points out that progress In the reduction of radio in- terferenco depends on the maintain- ing of transmitting stations on thelr assigned frequencies. Stations were directly alded in holding their fre- quencles constant by the establish- ment of standard frequency. stations, by measurements of station fre- quencies at the bureau laboratory, and by the transmission of standard frequency signals from the bureau station WWV. Two advances in radlo beacons were made recently. One was the comple- tlon of the development of a directive ystem which enables a ship or air- craft to follow a specific course with the aid of ordinary recelving appara- tus. The other the construction of a low-power beacon &apparatus which will be placed in service on buoys and may become an important new aid to navigation. In co-operation with Government and manufacturing interests the elec- tron tubes used in radio and methods for testing have been standardized. | Applications of the tubes have been made in numerous practical radio re- celving problems. In its radio stand- ardization rprojects and technical In- vestigations the bureau has co- operated with the various natlonal engineering and scientific societles and with the other Government de- partments and boards having to do with radio. Direct service has been rendered to various branches of the Government on a large number of technical radio problems. In co-operation with the coast and geodetic survey a method has been developed by the Bureau of Stand- ards for locating accurately the posi- tion of a surveying ship when the visibility is 80 poor that the coast cannot be seen. The method employed involves the combined use of acoustic and radio signals. A small bomb is exploded near the ship, the Instant of the explosion being recorded on a chronograph on board. The sound wave produced by the bamb is picked up by under water microphones lo- cated at two or more known posi- tions along the shore. When the sound signal reaches the microphone it is automactically sent back to the ship by radio, where the instant of its arrival is recorded on the chrono- graph. The time required for the sig- nal to travel from the ship to each shore station can be then found by multiplying the time by the speed of sound in sea water. With this in- formation the position of the ship can be quickly determined. The method is now in dally use by the coast and geodetic survey in connec- tion with sounding operations off the Pacific Coast. Formerly surveying operations were often limited to five or six days in each menth, due to the visibility being so poor that the shore stations could not be seen. Radio Developments in Past Year. Evidence of the rapidity of the growth in radio interest is indicated by the fact that in 1923, one large manufacturer sold $22.465,090 worth of equipment, compared with $11,286.- 489 in 1922, and $1,468,919 in 1921, ac- cording to the Department of Com- merce. The cost of radio work of the department in the past fiscal year was $206,738 compared with $139,200 the preceding year, but more operators tions were held and more operators licensed, and nearly a thousand more ships and stations were inspected. It seems probable that broadcasting is permanently established as a public | neccasity. and may be considered as in- dispensable in the average home as the telephone. The broadcasting of the pro- ceedings of the Democratic and Repub- lican conventions demonstrated its value In enabling the public to keep in imme- diate touch with important events of géneral interest. The number of class B stations in- creaced during the fiscal year from 42 to 54, resulting in some difficuity in providing satisfactory operating than- nels for them within the wave-length band reserved for this class. During the fiscal year class A ata- tions increased from 203 to 378. Thi increase was offset by the change in ciass C, which was reduced from 327 to 101. Class D stations number two. On June 30, 1923, we had a total of 573 broadcasting stations. On June 30, 1924, we had 535, a decrease of 38. The question of who will pay for broadcasting does not appear to require immediate consideration. The public 1l probabiy continue to contribute liberally through cost of equipment pur- chased. At present there does mot ap- pear to be a more equitable way of dis- tributing the cost, while, on the other hand, such stations must have con- siderable advertising value Justitying the expense of operation where owners are not benefited through sales of radio apparatus. The broadcast listener is an unknown Dependable figures indicat- ing the number of persons deriving pleasure and benefit from this new and fascinating service cannot be furnished. Its effect cannot be forecast, nor its value estimated. An accurate expres- sion of its views is unobtainable. Prior to the establishment of the broadcasting service, radlo inspection work was confined almost entirely to the marine service. The advent of broad- casting not only necessitated jnspection and careful adjustment of the broad- casting stations, but required an exten- sion of this work to other stations to prevent interference and insure, as far as possible, satisfactory reception by the broadcast listeners. During the fiscal year 1923 there were 6,933 Inspections made of ship stations : in 1924 the number increased to 7,72T. TONIGHT. Musical program by “Roxie and His Gang,”. direct from Capito!

The Navy Department is being flooded with requests from American radio manufacturers for the use of the German radlo patents recently offered on reciprocal licenses. A standard non-exclusive, non-trans- forable, but revocable, license has been drawn up and will soon be submitted to applicants with a re- quest for a list of their patents which would become avatlable to the Government. The process of going over the many applications and ac- companying lists of patents will re- quire considerable time, officials of the Navy Bureau of Englneering point out, indicating that no licenses will be {ssued for several weeks. All applications will not be granted; probably only those firms having patents believed of value to the Government will be cross licensed. Fifty-three applications already listed Indicate that many new sets may appear in the near future, in- volving the famous Schloemilch-Von Bronk reflex hook-up, which is the best known of German patents. More Power For B Stations. The first B station licensed to in- crease its power over 1,000 watts was WTAM of Cleveland, which has gone up to 1,500 watts provisionaily. Sta- tion WEAF of New York, is also said to have applied for such an increase in power, while applications from Chicago and a San Francisco station are also reported pending. This increased power Is provision- | al; If the stations cause undue inter- ference, or fail to serve the public satisfactorily, the speclal permits may be recalled by the Government. Tuning Short-Wave Stations. The Bureau of Standards has issued the following note on methods of adjusting your recelvers to short- wave or high-frequency stations: “Some broadcast receiving sets now in use cannot be tuned conveniently to statlons _ broadcasting on fre- quencies higher than 1.000 or 1,200— i e. not be'ow 300 or 250 meters. The third national radio conference rec- ommended that the broadcast band of frequencies he extended to 1.500 Kilocycles (200 meters). This empha- sizes the Importance of the produc- tion of sets which will tune con- veniently at the higher frequencies and the desirability of information on how to use existing sets so that all stations may be tuned In. The range of recelving sets which employ a alngle-tuned circuit (1. e, where the antenna is part of the tuned circuit) may be extended to the higher fre- quencles without much _difficulty. This applies both to crystal and tube sets. It can be dome very simply by providing a fixed condenser (about .0002 microfarad) in series with the antenna, which may be switched in or out of the circuit. The settings of the dials are different when the con- denser is in and out of circult. Shortening of the antenna likewise reduces the capacitance and con: quently increases the maximum fre- quency (minimum wave length) to which the set will tune. “In the two-circult and other more complicated recelving sets the ex- tenslon of the frequency range may not be so convenlent. A general rule, however, may prove useful. The natural frequency of a circuit is de- termined by the product of the in- ductance and capacitance in the eir- cult, the larger this product the lower the frequency (higher the wave léngth). To Increase the frequency to which a clroult will tune it is only necessary to decrease either the in- ductance or capacitance or both. The inductance may be reduced by re- ducing the number of turns, while a reduction in the number of plates or inerease in spacing of the plates re- duces the capacitance of a condenser. ‘The effective capacitance In a circuit.| may also be reduced by using two condensers In serles. Changes in re- celving sets of this type can, in gen- eral, be readily made by radio lis teners who construct their own sets. Six new class A stations were li- censed last week by the Department of Commerce, and five were transferred 35c “Danderine” does Wondlens for Any Girl’s Hair Girls! Try this!

RINEHART Author Wants to See Set on Every - Hospital Cot in the - Country. A radio on every bed in every hos- pital in the country is the hope of Mary Roberts Rinehart, who yesterday, in & letter to Mrs. Macpherson Crichton, chairman of the woman's section, in- dorsed the movement, fostered by the Washington radio hospital fund, to equip all local hosplitals with radio. Mrs. Rinehart is a member of the advisory committee of the radio hospital fund, and has expressed a deep interest in its efforts to obtain $40,000, the amount needed to install and maintain radio outfite In the hospitals and charitable institutions in the District. “To any one familiar with the pain- ful msnotony of the hospital ward day, where the coming of the trays at meal- time and the arrival of visiting doctors sre often the sole break in it writes Mrs. Rinehart, “it is often a fact that sheer tedlum retards recovery. “But with the coming of the radio the hospital ceases to be & place of dull- ness and of exile. Contact with the healthy normal world is re-established ; Interest in life returns. And with the interest comes the will to recover. “For those tragedies of all hospitals, the chronic cases, the day ceases to be a thing to be dreaded.
