AM Radio Kit for Soldering with Seven Transistors Superheterodyne 530–1600 kHz Box 125 x 75 x 30 mm For Electronics Education
You already have the maximum available quantity in your cart.
The AM radio kit for soldering is an educational set from which you can assemble a functional receiver for medium wave radio reception. The circuit is designed as a superheterodyne with seven silicon transistors, which the manufacturer claims offers stable operation, loud sound, and low power consumption. The receiver operates at low voltage and requires only two AA batteries (3 V). The kit includes a printed circuit board, all electronic components, a speaker, and a plastic box, so after soldering, you will have a compact radio ready for listening. The kit is intended for electronics enthusiasts, students, clubs, and school workshops where soldering and circuit work are taught.
While assembling, you will practically try out fitting components onto the board, soldering leads, connecting the ferrite antenna, tuning capacitor, and intermediate frequency transformers, and finally bringing the receiver to life and fine-tuning it. Tuning stations is done using a rotary knob along a scale in the range of 530–1600 kHz, with volume controlled separately. The finished radio fits into a box measuring 125 x 75 x 30 mm with a speaker grille and a coloured scale on the front. The package includes a circuit diagram that allows you to follow the signal path from the antenna through the mixer and intermediate frequency amplifier to the low-frequency amplifier and speaker.
- Type – medium wave AM receiver kit for soldering
- Circuit – superheterodyne with seven silicon transistors
- Tuning range – 530–1600 kHz according to the scale
- Power supply – 3 V from two AA batteries, batteries not included
- Box dimensions – 125 x 75 x 30 mm
- Control – station tuning and volume adjustment using rotary knobs
- Sound output – built-in speaker
- Purpose – electronics education and soldering practice for beginners and advanced users
- Contents of the package – plastic box, printed circuit board, speaker, ferrite antenna with coil, tuning capacitor with knob, transistors, resistors, capacitors, coils and transformers, LED, battery contacts, connecting wires, and printed instructions with a schematic in Chinese
For assembly, you will need a soldering iron, solder, and basic tools such as wire cutters and a screwdriver. It is recommended to follow the schematic and fit the components gradually from the lowest to the highest to ensure good soldering on the board. Before inserting the batteries, it is advisable to check all connections and the polarity of the electrolytic capacitors and transistors. The colour of the box may vary between different batches, but the components are the same.
This kit is a practical way to understand how a radio receiver works while also practising soldering on a real project. The result is a functional AM radio with a speaker that you can regularly use to listen to medium wave stations. With clear wiring and schematic, it is suitable for teaching as well as for independent home study. The kit makes a great gift for young technicians, radio amateurs, and anyone who wants to learn to work with electronics. Powering from low voltage 3 V makes it easier for beginners to bring it to life and measure.
