摘要: An electronic tuning circuit for AM receiver is disclosed which so designed that tracking errors are minimized by increasing the accuracy of constants coils, oscillation coils and capacitance elements incorporated in an antenna circuit, a high-frequency amplifier local oscillator constitute circuit. After has been mounted place, adjustment effected at one point receiving frequency band, or alternatively no such required.
