Commentary
FM/AM tuner kit with PLL that can be completed in 4 hours.
The front end, IF block and MPX section of GT-210 have been adjusted and wired on one printed circuit board.
In addition, all blocks such as power supply blocks and switch blocks are assembled on the Kencraft production line after adjustment.
A PLL circuit is used in the MPX section to realize a circuit resistant to secular changes and changes in temperature and humidity.
The front end uses MOS type FET and frequency linear type 3-row variable capacitor, and the IF stage uses high-integration IC and 2-stage ceramic filter.
This makes it possible to receive clear sound from a station located at a long distance or in a strong electric field area.
It is equipped with an MPX noise filter to cut out noise components that cause concern when receiving FM stereo broadcast transmission.
Equipped with FM stereo indicator using LED.
The AM tuner uses a high-integration IC.
It provides stable AGC characteristics regardless of whether the input is strong or weak, enabling AM reception with less distorted sound.
The bar antenna is designed to be built into the case.
Equipped with a meter for both tuning and signal.
It acts as a center tuning meter to indicate the best tuning point when receiving FM, and as a signal meter to indicate the strongest point of input when receiving AM.
