This paper describes the use of current-controlled inductors in a signal-seeking broadcast receiver. The use of these inductors as tuning elements results in a receiver with no moving parts. Although the idea of an automatically self-tuning receiver goes back several decades, its practical realization has been made more promising through the recent improvement in saturable-core circuit elements for radio frequency use. The receiver described does not represent a finished design for manufacture, but does show some presently obtainable characteristics in this type of instrument and the problems encountered in such circuits.
