AM- FM Radio Trainer
Provided with high quality printed circuit board with schematic printed on the surface. These have components placed over their corresponding symbols in the schematic drawing on the surface of the printed circuit board that ensure easy learning process and explain theory of operation of the radios. Constructed in sections.Trainer forms a “superheterodyne” receiver of standard am (amplitude modulation) and FM (frequency modulated) broadcast frequencies.
