Overview
FM Radio Kit 76-108 MHz with Automatic Station Search Soldering Set with Holder for 2 AA Batteries for Electronics Education

The FM radio kit is a practical electronic set from which you can assemble a functional radio broadcast receiver with your own hands. Once completed, it will capture stations in the range of 76-108 MHz and automatically search for them at the press of a button. The kit contains 25 components including a double-sided printed circuit board, integrated circuit, buttons, and a battery holder. It is suitable for students, electronics clubs, and home DIY enthusiasts who want to practice soldering and understand how a radio receiver works. The finished module can be listened to through headphones, so it does not disturb the surroundings in the classroom or at home.

Assembly includes soldering classic leaded components as well as one surface mount chip, allowing you to try both common techniques. The control consists of five buttons: power on, volume increase and decrease, and station search up or down. The cable of the connected headphones serves as an antenna, and an external antenna can also be connected via a jumper on the four-pin header. The radio is powered by 2 AA batteries with a total voltage of 3 V, and its operation is indicated by a yellow LED.

  • Type – FM receiver kit for soldering

  • Antennas – headphone cable or external antenna selected via jumper
  • Power Supply – 2 AA 1.5 V batteries (not included)
  • Indication – yellow 3 mm LED
  • Board – double-sided printed circuit board with component markings
  • Assembly – leaded components and one SOIC chip for surface mount
  • Required Tools – soldering iron, solder, wire cutters, and tweezers (not included)
  • Package Contents – printed circuit board, 4 resistors, 2 electrolytic capacitors 100 µF, 2 ceramic capacitors 100 nF, ceramic capacitor 33 pF, inductor 10 µH, 2 diodes 1N4148, transistor SS8050, receiver integrated circuit, 32 kHz crystal, yellow 3 mm LED, 3.5 mm audio connector, four-pin header with jumper, 5 buttons, and holder for 2 AA batteries

Before soldering, it is advisable to lay out and check the components according to the markings on the board. We recommend soldering the surface mount integrated circuit first with a flat soldering tip, and only then install the resistors, capacitors, diodes, and other leaded parts. After completion, clean the board of any residual flux, insert the batteries, connect the headphones, and turn on the radio with the power button. Solder in a well-ventilated room and place the hot soldering tip in a stand.

The FM radio kit combines fun with learning, and after assembly, it becomes a small pocket receiver for everyday listening. Thanks to the range of 76-108 MHz, it will capture regular radio stations as well as local broadcasts. It is suitable as a tool for physics and electronics lessons, for technical clubs, or as a gift for a budding electronics enthusiast. The combination of leaded components and the SOIC surface mount chip makes it a good soldering training exercise for beginners and intermediate users. The entire assembly can be completed with standard tools in one afternoon.
