Equipment for Education, Engineering and Vocational Training - AM & FM Radio Trainer - AM/FM Radio Trainer Kit has components placed over their corresponding symbols in the schematic drawing on the surface of the printed circuit board thereby maximizing the learning process and explain theory of operation of the radios. The radios are constructed in sections with each section being completely tested before moving on to the next, reducing difficult troubleshooting associated with some other kits. Trainer includes a high quality printed circuit board with schematic printed on the surface. The manual is easy to understand and assumes no previous electronics knowledge. Trainer forms a “Superheterodyne” receiver of standard AM (amplitude modulation) and FM (frequency modulated) broadcast frequencies. Object: 01. To Study AM RADIO RECIVER 02.
