Abstract

PURPOSE: To record only effective radio transmission signals surely and prevent waste of a tape, by discriminating tuning or detuning on a basis of the signal from a tuner and by controlling the sound recording operation to stop this operation for detuning.
CONSTITUTION: Broadcast signals from FM natenna 1 and AM natenna 2 have electric field intensity levels converted to DC values through IF stages 3 and 4, switch 5, IFA 6, and rectifier circuit 7, and these DC values are supplied to electric field intensity level discriminator 40. Discriminator 40 detects and discriminates surely detuning of the tuner and resets mode detection circuits 36W38 automatically foe detuning and controls the sound recording operation so that this operation may be stopped surely even if the user selects the sound recording operation.
