Abstract
A completely transistorized radio transmitter and a receiving system are described operating at 104 mc. The weight of the transmitter is under two pounds without the use of miniature parts. Design is for transmission of up to ten channels with bandwidths of 250 and 1000 cps. The channel reported has a carrier frequency of 2100 cps and was tested for EKG recording. Satisfactory calibrated records were obtained while walking and while on treadmill.
