AM/FM Radio Kit/Trainer (requires assembly-advanced)
Learn about and Build A Superhet IC Based AM/FM Radio Receiver. This Superhet 108 AM/FM Radio Kit is a superheterodyne receiver of the standard AM (amplitude modulation) and FM (frequency modulation) broadcast frequencies. The unique design of the Superhet 108 includes an integrated circuit (IC), 9 transistors, 4 diodes, and other related resistors, capacitors, coils, and misc. parts. Because good soldering practices are important, a soldering guide is also provided as well as a component color code and pictorial identification chart.The actual assembly is broken down into 9 sections. The theory of operation for each section, or stage, should be read before the assembly is started. This will provide the student with an understanding of what that stage has been designed to accomplish, and how it actually works. After each assembly you will be instructed to make certain tests and measurements to prove that each section is functioning properly. If a test fails to produce the proper results a troubleshooting guide is provided to help you correct the problem. After all of the stages have been built and tested a final alignment procedure is provided to peak the performance of the receiver and maximize the Superhet 108s reception capabilities. Runs on a standard 9VDC battery, not included. From Elenco.
