TITTMANN TO SING ON RADIO PROGRAM Will Take Part in Joint Re- cital of Myron Whitney Pupils Over WRC. A joint recital by Charles Tow- bridgq Tittmann, basso; Helen How- inson, soprano, and Charlotte Harri- man, contralto, will be presented by Myron Whitney as the principal fea- ture tonight of WRC's program. Mr. Thitney is éne of the best known \merican vocal teachers, with studios in New York and Washington. For & number of years he was one of Amer- fva’s foremost concert bassos, cxrry- ng on the traditions of his famous father, Myron Whitney, sr. who in his day was America’s greatest singer. The three singers Zir. W nitney will present tonight have studied with him for several years. Charles Trow- bridge Tittmann is known principally as America’s leading singer of Bach music, having sung at eight consecu- tive Bach festivals, and in most of the leading performances of Bach's works. He hus sung as soloist all the symphony orchesiras and at the Cincinnati festival. Helen Howi- son, who will be heard for the first time over the radio, has worked con- stantly under Mr. Whitney for a num- ber of years. She spent last Winter at the tainebleau School of Music, in France. and was awarded one of the two diplomas given her class. Charlotte Harriman, who has been studying three years with Mr. Whitney recently gave up her position at the First Baptist Church in Alexandria 1o accept the contralto position at the New York Avenue Presbyterian Church. Each of these artists will be heard in a group of songs, with Lucy Brickenstein at the piano Another interesting recital will be miven by Mary Knox Fitx, lyrie’ so- prano, and Geneva Fitx dramatic so- vrano, who will be heard in a group of solos and twe duets. Mary Knox Fitz is connected with the Peabody Institute of Music in Baltimore, while her sister iieneva has charge of the music at the Bastman School in Washington. Julius Ochs also will be heard in a violin recital, accompanied by his brother, Karl Ochs, The dinner music from WRC will be provided by Irving Boernstein's Hotel Washington Orchestra, while he dance program will be plaved by Meyer Davis' Le Paradis Basd. The weekly Blble talk will be delivered by Representative John C. Box of Texas, and there will be addresses by J. Fred Essary, president of the Gridiron Club, on " “What George Fon- tor FIFTEEN MINUTES OF RADIO EACH DAY BY JOSEPH CALCATERRA, Noted Authority on Radio. Al Rights Reserved.

The conventional schematic wiring diagram of such & circuit is shown in Fig. 2. This circuit, as can be seen at.a glance, consists of the circuit shown in Fig 2 of yesterday’s arti- cle with a stage of audio frequency amplification added to it for great- er volume, A double circuit jack nas been sub- stituted in place of the phones, and the terminals of the primary wind< ing of an audio frequency trans- former have been connected to the inside terminal springs of the jack. When greater distance is more de- | sirable than greater volume. a stage of radio frequency amplification, either tuned or untuned, can be added to accomplish this purpose. In that case_ the amplifier stage is added before the refiex stage instead of after it, and this stage of ampli- fication serves to amplify the signal before it reaches the reflex stage. The result, of course, is a more sen- sitive receiver that will work well on distant stations. * The functional diagram of this cir- cuit is shown in Fig. 3, while the music for the ladies .

Cinci conventional schematic diagram is! shown in Fig. 4 | ™ this arrangement, the signal | first passes through a straight radio frequency amplifier stage. Then it is passed into the reflex stage to be amplified at radio’ frequency. Detec-~ tion then takes place in the crystal detector circuit, after which the sig- nal is reflexed back through the sec- ond tube and amplifie¢ at audio fre- quency. These applications show two of the ways in which two tubes can be con- nected together in a reflex circuit to accomplish _different results. The first type shown in Figs. 1 and 2 is designed to give greater volume, while that of Figs. 3 andv4 is de- signed for greater distamce. _ The circuit shown in Figs. 1 and 2 is the equivalent of a three-tube cir- cuit having a stage of radio frequency amplification, a crystal detector cir- cuit and two stages of audio fre- quency amplification. The circuit shown in Figs. 3 and 4| is also equivalent to a three-tube cir- cuit, but in this case the equivalent circuit would consist of two stages of radio frequency amplification, a crystal detector circuit and one stage| of audio frequency amplification, GANNON “SIGNS OFF” AS WRC ANNOUNCER Leaves Radio Business to Engage in Stock Broking—Pioneer in Broadcast Work Here. ‘Wall Street has called away from the microphone the dean of Wash- ington's coterie of radio announcers —C. Feland Gannon of WRC. Gannon has “signed off” permanently, and will leave soon for New York, where he will engage in the more prosaic business of stock prokerage. Since the pioneer days of broad casting, Gannon's voice has been familiar to Washington's ever-grow- ing audience of radio listeners, both as an announcer and soloist. On numerous occasions he has filled gaps in WRC's programs as “Arthur Mc- Cormack, baritone.” A pile of com- mendatory letters followed his re- citals, but they were always address- ed to “Arthur McCormack.” Gannon has been announcing and singing at WRC since it made its ether debut August 1, 1923. His con- nection with the radio interests of Washington, however, antedates that by several vears. While WJH, the pioneer broadcaster, was entertaining radio fans, Gannon held the position at this station as director of pro- EHAIMS. When Roger Bruce Lum left WRC to join the staff of WNYC in New York Gannon automatically became the station's senior announcer. He also has taken an active part in the construction of programs at WRC as well as the handling of the station's mass of publicity material. During his caréer at WRC Gannon has introduced to the radio audienco scores of the Nation's most prominent men, in addition to virtually every ~adio artist who has appeared before the station’s microphone. Contact with the radio public has made him| who will | of his circle of friends sincere regret a wide learn with feaving. Gannon made his final appearance in radio circles Wednesday night at the radio revue in the new Washington Auditoriugn, where he assisted Wash- ington's three other radio announders in directing the program. Private Transmitters Barred. The Turkish government has ad- mitted on principle the installing of private radio receivers all over Tur- <ey, but radio transmitters for pri- vate use are strictly forbidden.
