AM側のｺﾝﾃﾞﾝｻｰC45が見つからず、英文の取説をじっくり見たところLM386の2Pと6P(ｱｰｽ)又は4P(ｱｰｽ)に基盤の裏側から接続する様になっていますので、C45は注意して下さい。 Read more

O kit é excelente. Muito boa a apredizagem. Read more

Esta súper completo, realmente es un kit educativo desde nivel básico a medio, pero bien estructurado y materiales de buena calidad, cuando empiece el montaje y pruebas comprobaremos su funcionamiento. Solo que llegó un poco aplastada la caja pero es muy posible que la empresa transportista no tuvo el debido cuidado. Read more

I bought this set because of the promise that there would be a booklet explaining in detail what each of the modules in the circuit do and why they are constructed the way they are. The booklet, while not super detailed (because it's not a textbook) does indeed live up to that promise. As a soldering exercise, it's on the easy side: I think with a bit of practice this can be assembled wearing mittens if need be. But it is sold as a beginners' learning tool, so that's absolutely appropriate. I work at a school where I am on duty in the Engineering Lab once a week, so this has been my time waster. Of course I won't be using it as a radio (all radio stations stream nowadays), but I'm happy with the purchase. Read more

２つ購入しました。一つは組み立て用、もう一つは部品の特性測定用や部品在庫用としてです。しかし、組み立てテキストが、細部まで気を使っているので驚いた。つまり、電源とアンプ回路から始まって、最後にアンテナとLC回路を作る形になっていて、回路毎に、直流電圧測定による動作確認や、信号発生器とオシロスコープを用いた回路特性測定をする仕組みになっているのだ。しかも、AMのみでなくFM も受信出来るのにも感動した。 Read more

With this review I hope give you some idea about what this kit does and doesn't do and how it can be a great learning tool for both young and old alike. This kit is very complete, everything needed for building a complete AM and FM radio is included in the box. All the parts are neatly laid out and placed on cards for easy identification. The construction manual is very easy to follow and it also includes tests needed to be done during the construction process as well as final tuning when complete. The radio's circuit board is laid out is with the AM section on the bottom and the FM on the top of the board. If you follow the manual you will be building the AM section first with the FM section second. This makes the construction easier as both the AM and FM sections of the radio are broken down into small sections, then a test to make sure everything is working before moving to the next section. The manual goes into how and why the circuits and other electronic parts do what they do and how they do it. This kit can be built with just a multi-meter or you can also use an oscilloscope for more complete testing and understanding of the parts and circuits, but the oscilloscope is not necessary for the build. This is kit is both a relaxing build and a great teaching tool. If you have teenagers in the house, this kit will teach how to make good solder connections of the parts onto the board. The board has more room between parts and solder pads, so the process is much easier to get the parts mounted to the board successfully. The board also has all the symbols printed on the board that you would normally see on a schematic drawing layout. This is a good way to see both symbols together and it helps in the learning process. The board also includes dedicated test points for doing the testing needed during the building process. This is one of the best kits to get your feet wet in electronics or as a very good teaching tool for young adults and adults alike. Once done you have a working AM/FM radio. Since this is a battery operated radio, its great to have around when the power goes out. I would recommend using a good 60/40 Tin Lead solder, with a diameter of 1mm, this solder is much easier to work with and make a good connection, you don't need all that heat on the board and electronic parts when learning. The provided solder is lead free and makes it more of a challenge to get a good solder joint when learning the soldering process. Fun project! Read more
