Abstract
A transceiver radio over a radio channel frequency for analog voice transmission with a receiver selective call, a generator selective call adjustable, and adjustable to different channels oscillator, wherein, in the condition ready-to-receive channels are connected sequentially and cyclically until a call is located and where, to establish a connection with another station channels are successively connected until a free channel, characterized be because both the ringer selective (8) as the selective call receiver (7), in the ready-to-receive condition, are adjusted to the station's own address and, for the establishment of a connection, are adjusted to the address of the party desired, because the frequency range of the selective calls is chosen, and the transmission is effected, in such a way that the selective calls are audible at the receiving end. Ng because during transmission, the selective call set to the selective calling generator (8) is continuously transmitted with a lower level of the call level, and in that a timing circuit (15) which automatically switches the transmitter- receiver to the ready-to-receive condition if said transceiver has neither transmitted information nor received said selective call transmitted constantly from the transmission station, for a predetermined period of time.
