WRG IS ENLARGING PARK ROAD STUDIO - Space Found Inadequate. Special Program to Mark Completion, June 1. Remodeling o the studios of broad- casting st.tion WRC, at Foutteenth street and Park road, has beem started, and when completed, will give the radio corporation station nat only a larger main broadcasting room but an additional small studio and an enlarged reception room. The work is expected to be finished by June 1, when a special christening program will be arranged from the new suite of studlos. The present space occupied by WRC was fitted up in the Fall of 1923, but with the enlarged programs hooked by the station, it has proved Inadequate. One of the greatest dif- ficulties encountered in broadcasting from the original studios was in ac- commodating the service bands and large choral or orchestral organiza- tions, and in obtaining their proper modulation for their music. Will Improve Programs. In the new main studlo, thie diffi- culty is expected to be overcome and ample space for organizations of a hundred or more persons will be pro- vided. The additional small studlo, which has been included in_the re- modeling plans, will enable WRC to run its programs more smoothly by eliminating the pauses often neces- sary in the past, when time was re- quired for the organizations to take their places in the studio. Under the new arrangement one number can be broadcast from the small studio, while a band, or or chestra, is being placed in the main studio, and then following the con- cert in the main room, the program can be switched lmmedlatel/ back to the small studio. ile the remodeling work is Deing carried on WRC will use a studio especially fitted up for its use in the Tivoll Theater Building, just across the street. The use of this studio has’ been given WRC by Harry M. Crandall. The plans for the new accomrmoda- tions for WRC were drawa by Wal- ter L. Tesch, engineer in charge at Ihe Park road station.

Morse, in- ventor of the practical telegraph in- strumient and code, first put them into practice in 1845 many intelligent citi- zens were actually terrified. Some of the more skeptical spoke of him as being in league with the devil. The fitst message sent over the line that had been constructed for the practi- car try-out was, “What hath God wyought?” Morse was a painter and not an electrician, but he combined the principles aid devices that electrical sciantists had produced up to that time and in that way won credit for the idea. He met with great opposluon in gétting the idea accepted. ! RADIO’S BEST OFFERINGS TONIGHT. .

Arriving only 10 hours after the disaster, he played a conspicuous part in establishing the emergency hospi- tals and caring for the injured and homeless. After nearly two months of iftensive rellet work in the dls trict, he characterizes this as the most destructive tornado this coun- try has ever suffered. The relief work Mr. Baker is direct- ing has included the care of 3,000 in- jured people, feeding, clothing and sheltering 20,000 homeless victims, and clearing hundreds of acres of fertile farm lands, which were lit- tered with trees, splintered timber, ‘The Balkite charger and Bal- kite “B"—the ideal power supply for your radip set.
