Abstract

PURPOSE:To ensure an effective use of the high sensitivity characteristics proper to a super-regenerative system, by adding an external controller including the detecting/discriminating function of received signals, the timer function and the oscillation control function to the quenching oscillation circuit of a receiver. CONSTITUTION:An external controller 10 consisting of an arithmetic circuit of a microcomputer or the like is added to the quenching oscillating circuit part 8 that includes a detecting/discriminating function of the received signal, timer function and quenching oscillation controlling function, respectively. Then for instance, whether the received signal is the last one of a consecutive detection or not is discriminated. And in case no received signal is detected, a timer is controlled to give a control every 15min to the base bias of the transistor Tr18 of the circuit part 8 and thus obtain the optimum oscillation. Such automatic control function is secured. If the received signal is detected meanwhile, the automatic control function stops. Then the sensitivity can be maintained for the state of reception.
