Abstract

PURPOSE:To prevent relative variation of carrier waves, by transmitting a reference carrier wave signal from a master station to a slave station on another line, in a communication equipment which makes the same broadcast from a number of transmitting stations. CONSTITUTION:A master station A generates a reference carrier wave with a carrier generator 2a, this is amplified and modulated at a transmitter 1 and transmitted from a transmission antenna 3, and the reference carrier wave is transmitted also to slave stations B, C on a communication line or an STL line L. At the slave stations B, C, after the reference carrier wave is offset for 0.1Hz-0.01Hz at carrier wave generators 2b, 2c, amplification and modulation are made at a transmitter 1 and transmission is made at a transmission antenna 3. Thus, at a district 4 where electromagnetic waves from each station can be made, although there is a momentary reception disable time, most of time can be receptionable.
