Commentary
The FM/AM tuner was developed with the aim of being a tuner for music playback and focusing on the basics.
Various characteristics have been improved by the front end of 4-row varicon using FET and phase linear type ceramic filter with 6 elements.
In addition, new technologies have been introduced everywhere, including 4-stage limiter circuits including monolithic ICs and double-balanced multi-demodulators using transistors.
A multi-path detection terminal that allows the optimum direction of the antenna to be determined while listening to sound, and a 2-meter type tuning meter that shows the tuning point at which distortion is minimized are used to give consideration to ease of use.
