A heterodyne radio receiver is adapted to reduce intermodulation interference at the first mixer output due to an undesired strong intensity signal. Since the output of a non-linear mixer can be expressed by: where U is the input signal, and comprises: (1) a useful signal R=ACos.P R .t (2) a local oscillation frequency signal H=B.Cos.P H t (3) a strong interference signal T=C(1+ w.Sin pt) Cos.P r t the degree of modulation of the interference signal on the useful signal at the mixer output, due to the term 3RT<SP>2</SP> in U<SP>3</SP> is given by: A similar formula gives the degree of interference modulations on the component in the mixer output at local oscillation frequency , viz: The interference on the wanted IF signal produced by the 12 R.H.T<SP>2</SP> term in the U<SP>4</SP> term is given by Thus, and the amount of interference on the I.F. signal is directly proportional to that on the local oscillation output of the mixer. A tuned circuit 19 therefore extracts the local oscillation component from the output of mixer 1. Its modulation is detected at 4 and changed in amplitude and phase by means 5 and 6 respectively such that, on applying it, so modified, to a terminal 9 whereby the output of the local oscillator 15 is modulated, the modulations on the IF signal, separated out by tuned circuit, is compensated for and cancelled. The items 19, 4, 5 and 6 may together form an adaptor kit for modifying existing standard radio receivers.
