The transmitter and receiver employed experimentally for repeating KDKA's programs from KDPM at Cleveland are described. The high power short wave transmitter at 8 XS (Pittsburgh) is described particularly in regard to the radio frequency condensers and inductances required. A description of the receiver and transmitter at the Hastings, Nebraska, repeating station KFKX is given.
