Abstract :
The system of equal-wave broadcasting is described, according to which the three first German common frequency transmitters operate. Two cables are necessary between the transmitters, in which the carrier frequency is between 1500 and 2500. Multiplication of frequency is accomplished by static frequency changers in three stages.
