ST-8044G
Commentary

FM/AM tuner equipped with active servo lock circuit.

It is equipped with an active servo lock circuit that automatically follows even if the transmission frequency shifts or the tuning frequency of the IF stage or detection stage fluctuates, and maintains accurate tuning.

The FM front-end uses a junction FET and a high-precision varicon in the RF stage to increase sensitivity.
A PLL IC is used in the MPX demodulation circuit.

The signal & tuning meter uses an LED tuning indicator that displays the tuning point with light.
