This DIY PLL radio receiver kit measures 71mm x 100mm and is designed for FM broadcast (88-108 MHz) and aviation bands (118-136 MHz). Powered by a 12V DC supply, it features an STC8H1K17 microcontroller with built-in PLL local oscillator, a digital frequency display with 7-segment indicators supporting 10KHz/100KHz steps, and a superheterodyne architecture with single frequency conversion at 10.7MHz IF. The kit includes TA2003 mixer and TA7613 amplifiers, noise squelch, automatic frequency saving, and adjustable frequencies for crystal and IF. Its rugged design supports high-gain antennas, making it suitable for long-distance reception. Assembly requires basic electronic skills and tools like a soldering iron and multimeter.
