Abstract

A control circuit (10), with a connection to a store (15), is connected to a data store (14) which in turn is connected to a tuning voltage generator (16). This is connected to the input stage (2) which receives signals from the aerial (1). The input stage is connected to an intermediate frequency amplifier (3) which is connected to a demodulation stage (4) and a carrier detector (8). The carrier detector is connected to an A/D converter (9) which feeds digital signals into the control circuit. The demodulator stage is connected to a receiver blocking stage (5) which in turn is connected to the AF amplifier (6) and the loudspeaker (7). The demodulator output is connected to the control circuit via an amplifier (11), a null detector (12) and a time constant switch (13).
