Abstract

The apparatus is a radio set wherein a first auxiliary oscillator is provided in the transmission device which is connected to the transmission mixer and during the reception operation, the transmission path between the transmission mixer and the main local oscillator is interrupted by a switch device. The switching off of the transmission frequency can also be achieved in that the transmission path between the transmission mixer and the first auxiliary oscillator is interrupted or between the transmission mixer and the power supply device of the radio set.
