The UTC TA2003 is AM/FM Radio IC ( FM F/E +AM/FM IF ) which is designed for AM/FM Radios.
FEATURES
* FM IFT, AM IFT and FM Detector Coil aren’t needed.
* Operating Supply Voltage Range VCC ( opr ) = 1.8 ~ 7V ( Ta=25°C). This experiment was done when I was a SWL lesson 145.625MHz Repeater . This circuit was based on a FM radio originally made for receiving FM broadcast stations. I modified its RF coil & local OSC coil & removed BPF at the front end & replaced.
