This compact trainer is designed to teach overall theory and operation of AM & FM radios as well as covering advanced points concerning testing and troubleshooting in radio engineering. 

The trainer consists of complete operational circuits for an AM superheterodyne receiver as well as an FM superheterodyne receiver which have been mounted onto easily accessible printed circuit boards. The circuits are logically laid out and feature the circuit block schematic diagram printed onto the surface of the board identifying functions, components and numbered test points.  Components including adjustable trim pots, tuning controls, and removable ICS are mounted on top of the boards to allow students access to them. 

A special electronic fault insertion system is built into the trainer for student instruction purposes.  The fault is activated by touching an electronic switch with a fault teaching probe.  Single or multiple faults may be introduced at any time.  Trainer includes comprehensive manuals and experiment sheets.
