NAVY BAND T0 PLAY ON RADID PROGRAM Will Be One of Closing Fea- | tures and Continue More | Than Hour. A concert by the United States Navy Band, under the direction of Charles Benter, headlines the’ attrac- tions of the broadcast program to- night of WRC. This event has been arranged as the cloaing feature and Wwill continue for more than an hour. A talk of especial interest will be that by Dr. Julia Seton, the inter- national lecturer and educator, an “Happiness,” to take place at 7:45. Catherine Louise Smith, pianist of the Caroltne Bender Studio, will' play - several solos immediately after Dr. Seton’s lecture, This tiny artist was heard over WRC nat many weeks ago and drew a sizeable load of appre- ciative letters. At Col. H. L. Bowlby, senior highway engineer, United States Bu- reau of Public Roads, presented un der the auspices ofithe American Au- tomobile Association, will tell the radio audience of Uncle Sam's achieve- ments and activities as a road builder. It is felt that this service being of- fered by the American Automobile Association is of considerable value to every tourist, since it discusases impartially all questions pertinent to automobile construction, upkeep and operation, road conditions throughout the country and other matters of vital concern to the motorist. At 8:30 Ruth Burns, a soprano of excellent reputation, will render a group of songs in which she will he accompanicd by George F. Ross. Fol- lowing Miss Burns. Ben Levin will he heard in ukulele and vocal solos, this feature being the last scheduled be- fore the Navy Band concert. Local Radio Entertainment Thursday, August 21, 1924.

ESPERANTO ADOPTED FOR WORLD RADIO USE A. R. R. L. Directors Decide on International Tongue, Which Thousands Speak. Bpecial Dispatch to The Star. HARTFORD, Conn., August '21.— After a two-year survey of the inter- national language situation, 'the Ameri- can Radio Relay League, with certain qualifications, has decided in favor of Esperanto as its offieial international auxiliary language, this action having been taken by the A. R. R. L. board of directors at their annual meeting in this city. This decision was made on the ground that Esperanto is easily the chief of the auxiliary languages, and has by far the greatest number of followers, with hundreds of thousands of users. Not wishing to enter upon the subject un- advisedly, the league first communicated with all of the national amateur radio societies of the world, and all of these which expressed an opinion in favor of Bny artificial language recommended Esperanto. Interest in an international language developed rapidly among members of the A. R. R. L. following the successful communication in radio telegraph code between transmitting amateurs in the United States and Canada and those in many foreign countries. The necessity for the indorsement of an auxiliary language has become particularly ap- parent as a result of the increasing interest of amateurs in international communication during the past year, There is every reason to suppose, the A. R. R. L. belleves, that radio com- munication in code between the pri- vate citizens of one country and those of another will become even more popular the coming winter, mak- ing the use of an auxiliary language by the amateur radio operators of the world almost Imperative. Esperanto socleties exist in most of the large citles, it was pointed out, and the language may be learned in a very short time. ENGLISHMEN SUPERIOR by Ruth George F.

NEW YORK, August 21.—English- men make bettar husbands than Americans, because they “treat their wives as companions and not as American husbands treat theirs, as dolls, spoiling them with presents, furs and - jewels, .

Regeneration—The Dr. Jekyll and Mr. ~ Hyde of Radiom—Part 1L Tn the regenerative oireuit the ascillations preduced by the escillator action of the tube combine with the received oscillatian to produce a stronger grid voltage variation and circuits be tuned to the ency beca: the frequency of the local esolllation must be the same as that of the received asoillation. The frequency of the local oscillation is controled by the condenser across the &rid ooll while the intensity is con- troled by the coupling adjustment be- tween the grid and plate coils. In regenerative circuits this ability of the tube te act as an oscillator is very desirable and increases consid- erebly the distance range of the set and the intensity of the signals re- oceived. l‘ det. It i diffieult to find cuit which compares in ficiency with the regenerative detector eireuit. Set Has Limitations. ‘The enerat! circuit, however, has its limitations, and, while it is very eficient over comparatively great distances when used with a good aerial, it will not give very good results when used with a very small indoor or loop aerial for re- ception over distances of more than 500 miles. For this purpase it is necessary to use some methed of increasing the sansitivity of the receiver and make it respond to the very weak im- pulses recelved by the ineffielent aerial, Accordingly some form of radio frequency amplification must pe used. It here that the tendeney of,the tube to act an oscillator causes trouble, for, while it is very desirable in detector circuits used without radio frequency amplification, the tendency of the tubs to act as an oscillator when used in radio frequency circuits throws the circuit into oscillations and makes for a very unstable circuit and unsatisfactory receiver. If it were possible to eliminate the tendency of the circuits to act as oscillator circuits this trouble would not be present In radio frequency circyit§ and the signals eould be am- plified withoyt any trouble. Cause of Oscillation. The conditions which aid the tend- ency of & circuit to go into oscilla- tion are low resistance; resonance be- tween grid and plate circuits; capaeity coupling between the grid and plate circuits, especially the capacity exist- Ing between the plate and grid ele- ments of the tube and inductive feed- back from plate to grid circuit pro- duced by coils in the grid and pl: e circuits which are placed in the TWO reasons you like them —delicious Fish ready-mixed with fresh boiled potato, You Save $500.00 to $2,000.00, THINK OF IT!

Obviqusly, if we want to get rid of the bad effects of regeneration in these circuits, we can do so by elimi- nating the facters which tend to aid it and by geing a step further and introducing elements which tend t> suppress any tendemcy of the cir- cuits to go into oscillation. Ingreaning the Resistance. The resistance in the circuit can be increased by actually introducing resistance in the circuit; by grid control with a potentiometer which causes a grid current to flow, thereby introducing the equivalent of resist- ance, by shunting the windings of the radlo frequency transformers by high registances; by using transform- ¢r8 with iron cores and other such methods. While these methods elim- inate the tendency of the circuit to &o into pxcillation, however, they also tend to decrease the- sensitivity and selectivity of the cirbuit so that they are at best a metessary evil. It is, of course, easy to prevent the grid and plate circuits of a tube from being in resonance with each other by proper: designing or adjusting the elements in the circuit. This, nowever, is not desirable because it also reduces the efficiency of the circuit. The next possibility is the elimina- tion of the tube grid-to-plate capa- city. This can be done by proper design of the tubes and by the neutralization method used in Hazel- tine’s neutrodyne circuit, and pro- vides the best method of overcoming the undesirable tendency without the introduction of other undesirable elements. ‘The next method is the elimination of induetive coupling between the plate and grid circuit of the type which aids regeneration and the sub- stitution of a type which suppresses any tendency of the circuit to oscil- late. This method uses a tickler coil in the same manner as the ordinary regenerative circuit, but reverses the polarity of the tickler coil with respect to the grid coll producing the “superdyne” circuit. The use of these methods elimin- ates the tendency of the circuit to go into oscillation, making it simple to operate without decreasing its efficiency. In this way regeneration is allowed to come in when In the form of Dr. Jekyll, but kept out when he tries the tricks of Mr. Hyde. Boy Killed in Auto Wreck. Special Dispateh to The Star.
