BIG PROBLEM FACED Synchrenization of Stations Regarded as Technical ]‘ NEW STARS IN THE RADIO FIRMAMENT Development. | | Brnchronization of broadeasting sta- tions, like television, still is in the experimental stage. Tts development to a standard of | substantial service to broadcasters and | the listening public is regarded as one of the most important technical problems confronting etation owners, radio engi- neers and the Federal Radio Commis- | sion. Expect Great Progress, | If several stations by synchronizing can broadcast simultaneously on the game wave length without heterodyning | or otherwise impairing reception great progress can be made in overcoming the obstacle of channel shortage, which now necessitates limitation of the num- ber of stations and restriction of their hours on the air, ! Several stations have asked the com- mission for permission to experiment | with synchronization. Dr. H. Del- linger, chief engineer for commis- | sion, says that experiments should be encouraged. but that the broadcast audience should be protected from the onjectionable effects of unsucce: periments. He says the goa experiments should be to:show, first, the attainment of the necessary control of frequencies: second, the nature and amount of interfersnce caused, and. | third, the effect on program servies to the listener. One Method Successful. Dr. Dellinger declares that the send- ing of a control ffequency by wire from a single point to each station iz the only method of synchronization that has been successfully accomplished in practice. These methods are: Inde- | pendent frequency standards in each | station by means of temperature-con- trolled piezo oscillators or tuning fork | and harmonic ampiifier; broadcast fre- | quency picx-up by manual control or | automatic control: low-frequency pick- | up. and high-frequency pick-up by beats | between two, step up from modulation frequency and step down. DIRIGIBLES TO HAVE | WIDER RADIO RANGE, w U. 8. Airships Will Be Able to Signal to All Parts of World. By the Associated Precs. Radio transmitters canable of sendinz | siznals to virtually every part of the| world will be installed in the t'vo mam- moth dirigibles, the ZR-4 and ZR-5, to be_constructed for the Navy. . It is the desire of th: Navy Depart- ment that the new rigid airships b» equipped with apparatus which will | have a communication range equal to their cruising radius, which will be mere than 8,000 miles. In case either chip should make transpacific flights its crew could keep in communication with Lakehurst or Washington virtually all the way. It has been decided to use the Los| Angeles as an experimental ship in de- | termining the designs for the radio equipment. Steps are being taken to develop equipment which will replace | thet now installed on the Los Angeles. | Hoth the intermediate and high fre- | quency sets will be replaced hy the Iatest type transmitters, and the pres- | eat wind-driven power generator will | b2 removed and engine-driven power | units substituted. Navy engineers say the present radio | compass will be allowed to remain in- | tact, as it hes given satisfactory service, | elthough it is possible that the receivinz | equipment may replaced by some of more modern design. | The ships are to be powersd with | eight engines instead of five, a5 in the | case of the Los Angeles, and ths igni- | tion systems of engines will be shisided i~ improve radio recention on board. ‘The ships are to be of 6,500,000 cubic | feet cepacity, which is approximataly | three times the size of the Los Angele. | RADIO FOR CHINESE SHIPS. | Beageing Steamers of 500 Tons Must Install Equipmsnt. SHANGHAI (®).—The ministry of | communications has ordered all Ghinese | oceangoing steamships of 500 tons and | over to install radio equipment Wireless stations are also required on the following: All steamers above 300 tons having accommodations for 100 passengers or more, plying between places at or more than 130 nautical miles from the coast and covering more | than 500 nautical miles each trip: all | pilots’ boats.

Desks, tabulating | machines and a staff of trained writers, | iabulators and political analysts will work in this room, condensing the tre-‘ mandous volume of the news report into statements suitable for broadcasting. | In order to break the strain imposed | on listeners who might otherwise grow weary of a news story lasting for hours, a gala program of entertainment has been arranged. From time to time these entertainers will go on the air. The | news story, however, will have prec- {edence over entertainment, and when- ever an important phase in the election | is developing. the broadcasters will fol- | low it through to its conclusion. Graham McNamee will be master of | | ceremontes for the entertainment fea- | tures of the election night program.) | Artists featured in the following radio | fratures will contribute to the program of entertainment: Soconyland Sketches, | Panorganum, New Radio Invention, Is Small but Noisy By the Associated Press. PARIS—A panorganum, which is a megaphone of great power, a radio receiver and a phono- graph, has been invented at the Paris Museum of Arts and Crafts. No bigger than a portable har- monium. the panorganum can fill the biggest hall with sound, carry- ing the voice of a lecturer, the notes of a phonograph disc or mu- sic from a distant radio station greatly amplified. Public speakers may make their speeches before an ordinary tele- phone receiver placed on the pan- organum, and, although speak- ing softly and easily, their words will be clearly audible in any part NOVEMBER 4, 1928—PART 1.
