Overview
AM FM Radio Kit for Soldering HX218 with CXA1691BM Chip 88–108 MHz and 530–1600 kHz Red Box with Antenna for Electronics Education

The HX218 radio kit is a soldering set from which you can assemble a functional portable receiver for both FM and AM bands. The core of the entire circuit is the integrated circuit CXA1691BM, which handles signal reception, processing, and sound amplification for the speaker. The radio covers the range of FM 88–108 MHz and AM 530–1600 kHz, allowing it to capture common radio stations on both very short and medium waves. All components fit into a plastic box with a scale and a retractable telescopic antenna after soldering. The kit is suitable for electronics education in schools, in technical clubs, and for DIY enthusiasts who want to try soldering on a real product.

On the printed circuit board, resistors, ceramic and electrolytic capacitors, coils, ceramic filters, a tuning capacitor, and the chip itself are gradually installed. The ferrite antenna with a wound coil is used for receiving medium waves, while the telescopic antenna on the top of the box is designated for the FM band. Stations are tuned using a rotary knob, the second knob controls the volume, and switching between FM and AM is done with a sliding switch on the back. The circuit operates with a power supply voltage of 3 V, the operation of the radio is indicated by an LED, and sound comes from the speaker or the headphone jack. The circuit is built around a single chip, making it easy to see what each part of the circuit does.

  • Type – AM and FM radio kit for soldering
  • Model – HX218
  • Integrated Circuit – CXA1691BM
  • FM Band – 88–108 MHz
  • AM Band – 530–1600 kHz
  • Power Supply Voltage – 3 V
  • Controls – tuning knob, volume knob, and FM/AM switch
  • Sound Output – built-in speaker and headphone jack
  • Antennae – telescopic for FM and ferrite for AM
  • Box – red plastic with frequency scale
  • Package Contents – red plastic box with telescopic antenna, printed circuit board, CXA1691BM chip, speaker, tuning capacitor with knobs, volume potentiometer, ferrite antenna with coil, coils and ceramic filters, resistors, capacitors, LED, headphone jack, battery contacts, and connecting wires

When assembling, it is advisable to proceed carefully and install components from the lowest to the highest, starting with resistors and small capacitors, then coils, filters, and electrolytic capacitors, and finally the chip, potentiometer, and tuning capacitor. A standard soldering iron with a fine tip and solder suitable for electronics will suffice for soldering. Before placing the board into the box, it is worth checking the orientation of the electrolytic capacitors, LED, and chip. Store the finished radio in a dry place and clean the box only with a dry or slightly damp cloth.

The HX218 kit combines practical soldering practice with an understanding of how a radio receiver for two bands works. The result is not just a practice board, but a usable radio housed in a red plastic box that can be used for listening. The kit is suitable as an educational tool for pupils and students, as a project for an electronics club, and as a gift for budding DIY enthusiasts. With the reception of both AM and FM stations, one can try both the most widespread methods of radio broadcasting on a single product. The set of components, including the box and speaker, allows you to assemble a complete receiver ready for listening.
