Silent Telautographs Write Directions to Radio Artists
TO ELIMINATE all interfering noises in the National Broadcast Studios, engineers are installing noiseless telautographs which write out directions to performers, thus doing away with the old method of waving the hands to give signals from the control room. The telautograph is placed near the microphone, directly before the eyes of the performers, so that directions can be read without the least difficulty.

MORSE CODE TYPEWRITER
A HEAVY-FISTED ham was Willard Guthoerl—and no one was more aware of it than he. His brutality was spent entirely on his sending key, however; hams from coast to coast and beyond the seas complained of his Morse signals.

From bustling Shanghai and fast-growing Nanking near the eastern coast, to Chengtu in remote Szechuan province, from the far reaches of Hopei province in the north to Yunnan in the extreme southwest, countless receivers blare forth a cacophony of western and Chinese music, announcements, speeches.
