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.
