Claims (5)

1. Radionachrichtenempfänger mit einem Empfänger zum Demodulieren empfangener Signale, einem Dekoder (35) zum Dekodieren der demodulierten Signale, einem mit dem Dekoder (35) verbundenen Oscillator (70) zum Erzeugen eines Bezugszeitsignals und mit einer ersten Stromversorgung (60) mit einer ersten Spannung, gekennzeichnet durch eine zweite Stromversorgung (23) mit einer zweiten Spannung, die höher als die erste Spannung ist, einen Versorgungsschalter (80), der mit der ersten und der zweiten Stromversorgung (60, 23) verbunden ist, und durch eine Schalteinrichtung (22) zum Zuführen der ersten Spannung zum Oscillator (70), wenn der Versorgungsschalter (80) geöffnet ist, wobei die zweite Spannung dem Oscillator zugeführt wird, wenn der Versorgungsschalter (80) geschlossen ist.
2. Radionachrichtenempfänger nach Anspruch 1, dadurch gekennzeichnet, daß die Schalteinrichtung (22) eine Diode ist, die zwischen den Ausgang der ersten Stromversorgung (60) und den Ausgang der zweiten Stromversorgung (23) geschaltet ist.
3. Radionachrichtenempfänger nach Anspruch 2, dadurch gekennzeichnet, daß die erste Stromversorgung (60) eine Batterie und die zweite Stromversorgung (23) ein Spannungswandler zum Umwandeln der ersten Spannung in die zweite Spannung ist.
4. Radionachrichtenempfänger nach Anspruch 1, dadurch gekennzeichnet, daß der Dekoder ein CMOS-Schaltkreis ist.
5. Radionachrichtenempfänger nach Anspruch 1, dadurch gekennzeichnet, daß der Oscillator ein Quarz-Oscillator-Schaltkreis ist.
