Simple FM Receiver Pocket FM Radio by BF184

It is a pocket receiver that I built. The idea was to use a simple receiver, but can be used to escape to 3 times viewed. My previous 6-transistor receiver was more complicated and requires 12 volts. This means that 10 AA batteries. I designed and built acircuit board, and built a small aluminum box will hold Comact as possible.

There is nothing wrong with this design. The detector has a simple Colpitts oscillator is of a type often used in other receptor super-regeneration. It’s natural for yourself. The sensitivity for this type of detector is relatively low, but it’s simple and easy to get work. As always, gave me a feedback control to determine the optimum point of operation, ie. maximum sensitivity and minimum SCA / stereo subcarrier beat.

Simple FM Receiver by TDA7000

With the TDA 7000 you can build an FM radio with a minimum of components; most of them so easy to manage…like the ceramic capacitors that do not require polarization…and only two resistors. The components you will employ will be of small dimensions and low cost. Even the integrated circuit itself, the TDA 7000, is not of great cost.
