fm radio receiver


Posted on Feb 6, 2014

A very simple circuit for FM receiver, no IC required, and only a single transistor. I`m not sure whether this transistor works or not, I`m going to try this out. Have you guys seen this before It is a regenerative or super-regenerative simple radio receiver. Read about its problems in Google. It is too simple to be a real radio and is just a cheap child`s toy. Another guy was in this forum and for hundreds of posts

about it he couldn`t make it work, except to pickup the sound from a powerful TV station very close to him. I do not think it is pointless to construct such a radio - if the point is to learn. It is not a replacement for a good design that has been well constructed and the performance will be poor at best. It is fair to say that this kind of radio represents what many used in the early days of radio. During those early days there was far less RF junk. The full attention of a skilled operator might improve reception but there are limits. I do not think that the construction of a good radio is within the capabilities of a beginner or even most advanced hobbyists - if "good radio" is defined as what might be commercially available today. Some can do it but not a large portion of that group. I do not think it is pointless to construct such a radio - if the point is to learn. It is not a replacement for a good design that has been well constructed and the performance will be poor at best. I meaned, if it only picks up the signal from tv station but not radio station. But it`s good to try it. I`m going to try since it is not a complicated circuit. I meaned, if it only picks up the signal from tv station but not radio station. But it`s good to try it. I`m going to try since it is not a complicated circuit. It has a variable capacitor for you to tune the frequency it receives. It will pickup airplane transmissions, FM radio or TV...
