Abstract

PURPOSE:To inform the vacant line to the users, when the communication line is vacant for a given time, by the operation of tone squelch release switch from the station to be transmitted. CONSTITUTION:When the transmission microphone 6 is hooked off from the hook for transmission, the tone squelch release switch 8 is operated and when the operation of the tone squelch 7 is off, the timer 9 is simultaneously set. The timer 9 counts the time when the communication line is continuously vacant, by the output of reception section 3, and if the line is busy before a predetermined time is not reached, the timer is reset and starts counting after the vacant line again happens. If the state of vacant line keeps more than a given time, the timer 9 operates the oscillator 10, the tone signal is produced from the reception speaker 4 through the reception section 3, allowing to inform the user that the line is vacant.
