Product Description
Learn & 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.;

 Excellent kit February 21, 2008

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.

I'll make this short. If like me, you miss building those kits--this is the one you want. At first I thought it would be too easy--I haven't done it yet, but I did open the box and give it the 'quick once over'.
Apparently, it is 'just' complicated enough to keep my interest--I would have perferred building my own cabinet stereo...but they don't exist anymore. So I settled for this little one. Oh yes, this comes with a small speaker.
All you technos who want to build your own radio (including the soldering and circuit board parts) that will fit into a small shoe box...this is the one to get! (it was also the only one I could find on the internet--those Snap-on and Spring Clips aren't my bag).
So, it gets my five star rating.
BYE!
great toy for learning March 15, 2010

if you are a electrical engineer want to know about a about radio, here is no better way to play with this Toy. with a proper O-scope and function generator, you can learn much more about RF theory than reading a book.
highly recommend. I also want to self assemble a multi-meter and power supply.

This product can neatly packaged with well written instructions. I have built kits before, but this one contained testing instructions that are done during the building phase. If you like to build small projects, this kit is an ideal project to fill that need.
Lot's of fun. June 15, 2009

Very nice kit. Only amplifier was oscillating. Just place the extra provided capacitor over powerconnection of IC and over the input of the IC and ground a resistor of 10 Kohm and all is OK. It is a lot of fun to build the radio and reception is above expectation.
