PURPOSE:To bring automatically an idle channel to a talking channel, to release forcibly an idle talking channel retrieval and to attain ease of correspondence even when no idle talking channel is found out by storing a frequency data corresponding to an oscillation frequency at call to a storage means and storing a group code to a group code storage means. CONSTITUTION:The equipment is in the reception state when no special operation is executed. In starting a program, whether or not the setting of a call sign code is selected is detected by a code selection means 101. A frequency data control means for control of a frequency is shown in caption 157, a call operation control means for control in a call operation troutine is shown in 158 and a data input control means controlling decode of an input data when a data is inputted is shown in 160. The equipment releases the retrieval of an idle talking channel and goes to a transmission/reception routine when no idle talking channel is found out in the call routine with a push-to-talk (PTT) switch 14 turned on. |
