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.

FM Receiver 4 Transistor by BF184
This is a pocket sized receiver I built in 1994. The idea was to make a simple but useable receiver running off 3V. My previous 6 transistor receiver was more bulky, requiring 12V. This meant 10 x ...
FM - AM Regenerative Receiver by 2N2646
The following is a design for a separately quench super regen receiver I first tried in early 1992. It worked far better than any other solid state design, so I built a portable version for us ...
FM Radio TDA7088 Receiver
The electronic diagram of the monophonic FM receiver made with TDA7088T is shown on Pic.4.12. If built with SMD components it can be placed in a matchbox, altogether with two button-type batte ...
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 ...
One Transistor FM Receiver by MPF102
This radio is sensitive enough to tune 20 stations across the FM band, some with volume high enough to drive a small PM speaker. The ability to tune 88.9 MHz and 89.1 MHz is testimony of its s ...
