AM Radio

Junior EngineeringInter-Engineering

The radio is a simple AM circuit where the tuning, demodulation and amplification can be identified easily from the diagram giving the tutor the opportunity of explaining each of the functions. Reasonable reception of the medium waveband is obtained without the use of a very long ariel but the project does require reasonable dexterity with the soldering iron.
