An error detection circuitry for detecting an error on a transmission path between a radio system (10, 12) and a transmitter is disclosed. The circuitry comprises means (16) for measuring the magnitude of a forward radio frequency signal directed from the radio system to the transmitter; means (16) for measuring the magnitude of a backward radio frequency signal directed from the transmitter to the radio system; and means for comparing the magnitudes of the forward radio frequency signal and the backward radio frequency signal. In a preferred embodiment of the invention a self-synchronization is provided for synchronizing a sampling of the output voltages of detecting circuits (24, 26) relative to the occurrence of a signal on the transmission path.
