A device for the automatic retuning of the channel of selection of a radio receiving or radio-transmitting device apparatus which contains a frequency detector, the input of which through a limiter is connected up to the heterodyne of the receiver or the exciter of the transmitter, and the output through a filter to the controlling elements of the retuning channel, which has the distinguishing characteristic that for the purpose of improving the precision of the retuning in a broad range of frequencies the frequency detector is designed in the form of a system of connected circuits the expression of the change of voltage on the output of which as a function of the value for the frequency deviation coincides with the expression of change of the value for the reactiveness of the controlling elements as a function of the voltage applied to them.
