Abstract: A circuit arrangement for selecting a radioelectric signal from a number of signals receivable by a signal receiver equipped with a character display device to enable at least two selection modes of the radioelectric signal. The circuit arrangement has a controllable oscillator, the frequency of which is determined by a control loop depending on a binary number N supplied by a processing unit on the basis of code input data. The control loop has frequency dividing means providing a first signal from the controllable oscillator depending on the number N and the comparator for comparing the first signal with a second frequency reference signal to provide a third signal for the required tuning. A memory circuit has a number of cells for digital storage of data relevant to the signals being tuned into. The said number N can be supplied both in direct response to the coded input data or by calling up data from the memory circuit.
