Abstract

PURPOSE: To make it possible to stabilize an auxiliary signal to a high degree by supplying a signal, obtained by dividing the output of a voltage control oscillator, and that, obtained by dividing the output of a transmitting local oscillator, to a phase modulator and then by controlling the voltage control oscillator by its detection output.
CONSTITUTION: An auxiliary signal for previous arrangements between a master station and subordinate station is inserted by the FM-modulation output of voltage control oscillator 22. Then, a signal, obtained by dividing 23 the output of oscillator 22, and that, obtained by dividing the output of a transmitting local oscillator for generating a transmitting carrier, are supplied to phase modulator 24 for phase detection, thereby exercising control over oscillator 22 by the detection output. Consequently, the auxiliary signal can be stabilized to a high degree by using oscillator 22.
