Toys and Games Reviews of AM/FM Radio Kit/Trainer (requires assembly-advanced)
Customer Review: Excellent kit
Summary: 5 Stars
If you're a tech buff, you'll love this. I'm building this for my Auto/mechanics class in High School, and this is my latest project. I love it. I've finished the AM part and am halfway through the FM part, and the AM part worked the first time I tried it. It sounds very loud and clear after adjusting the coils. Putting it together was an awesome experience, and I couldn't wipe that grin off my face when I turned it on and it worked. The instructions are very clear, they get straight to the point and have you do some testing with a multimeter along the way to make sure you didn't screw anything up. Great kit, just three tips:
Don't drop the AM antenna. It is little more than a bar of iron, and it WILL crack into several pieces.
Don't forget to put the plastic o-ring under the volume potentiometer.
On the AM/FM tuning gang capacitor, make sure you put the two screws on first BEFORE soldering it to the board. If you don't do this, it will cause the PCB to noticeably bend, and that's no fun.
Description of 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.Science Toys
