- This time I got myself a small DIY kit from Amazon: The CF210SP AM/FM Radio. It's a simple little kit and I bought it in the hopes to relive a bit of my youth when I had an educational electronics kit, with which you could build AM radios from discrete components. However, this kit here comes with a few caveats: Chinese instructions, a less than stellar case and other ill fitting bits and things.

You need to test all the ceramic capacitors and be prepared to throw them away. I am sure they hoover up reject capacitors. It can really mess up the FM radio. Don't bother assembling the AM part. it is the most un-selective POS I have ever met.
Hi there. What do you mean by "non selective POS". Do you mean lack of AM stations or that the AM part of this kit is a garbage?
One thing that would help would be instructions in the world's Lingua Franca, namely English.
I built one. The most disappointing Chinese kit I ever built. In general, I do like Chinese radio kits, and the six and 7 transistor AM ones I built worked well.
The actual circuit design is quite reasonable, remembering its simplicity. One IC for FM, one for AM (the traditional MK484 / ZN414 type clone) and an audio amplifier. Mine worked to a level I felt was satisfactory for something so simple.
But the kit was let down by poor quality of components, a PCB that was difficult to solder (and the copper came off when it got hot) and the dreadful, ill-fitting case and mechanicals. :-(
Wooow damage transistor........hahahajahahahah... That is ic sir not transistor...its like ys414 mk484 zn414.....ic for am radio...
Are you okay sir.....
😂
I never got a parts list or a schemaic just a photo useless i wanted to learn something i suppose i did
How to buy garbage.
very helpful thank you
The AM part has two stations interfering with each other and everything else over the whole AM band. The FM part does nothing more than hiss.
I just got one of these kits in Chinese. Slightly different but your presentation helps.
Can't believe you got it to work at all .
Hey. I also soldered this kit recency. Could not find any AM station though 😐 I wasn't expecting much from this, at least I had some fun building this and FM part works at least
I read a comment from someone that said don't solder the short tab on the tuner because it shorts the am section. I haven't soldered the kit yet, so I can't give more detail than that. Hope it helps you!
Yeah.. or maybe I have soldered the variative capacitor incorrectly, as there are at least 2 ways to solder it
Excellent craft, thanks for all the information.
