Description and Specification for Lab Tenders
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. Trainer forms a “superheterodyne” receiver of standard am
(amplitude modulation) and FM (frequency modulated) broadcast
frequencies. Constructed in sections.
