ABSTRACT:
In a mobile radio communications station, a communications reception frequency is generated and a time sequence of a plurality of reception monitoring frequencies is separately generated. A reception frequency is switched between the communications reception frequency during a communications reception and a current one of the monitoring reception frequencies during a monitoring reception. More particularly, separate frequency synthesizers are provided for communications reception on the one hand and signal strength monitoring on the other hand. The frequency of the synthesizer for communications reception remains fixed during the course of a communication. The synthesizer for signal strength monitoring need not be as accurate as that for communications reception. Furthermore, since the synthesizer is used only for signal strength monitoring instead of for both communications reception and signal strength monitoring, more time is available for switching between frequencies.
