Solid state AM/FM tuner developed aiming at high sensitivity and high selectivity.
An IC and mechanical filter are used in the IF stage to prevent interference.
It uses an LC-type full-fledged carrier leak filter to prevent 19 khz and 38 khz carrier leaks.
It uses a signal meter that shows the electric field strength and a tuning meter that shows the accurate tuning point.
Equipped with a muting switch that can cut out unpleasant noise during tuning.
A mechanical filter is also used in the AM circuit, and high sensitivity and high selectivity are obtained by combination with ferrite bar antenna.
