3-23MHz R10 PLL Shortwave Receiver Kit High-Sensitivity AM Radio Shortwave Broadcast Receiver

Purchase Instructions:
- This kit requires buyers to complete the soldering themselves (SMD components are pre-soldered) and perform debugging.
- Assembly involves risks. Buyers should assess their technical skills and available equipment to avoid installation failure.
- After purchase, contact customer service to obtain the instruction manual (electronic version).
- The kit includes all circuit diagrams but does not provide PCB design files, microcontroller source code, or firmware.
- The kit is shipped as individual electronic components. The assembled product images shown are for reference only.
- If any components are missing, please contact customer service.

Features:
- It utilizes the STC8H1K17 microcontroller as the main control, with a built-in PLL local oscillator covering 3-23MHz. It includes a frequency display circuit (using a 7-segment digital tube, displaying units in 1KHz. The photo has color differences; the actual display is red). Step increments support 1KHz/10KHz/100KHz.
- TA2003 for mixing + TA7613 for intermediate/low-frequency amplification. With a superheterodyne architecture and an IF of 10.7MHz. It supports automatic station searching.
- Original code by our store. Features an onboard digital control volume potentiometer, supports configuration auto-save, and allows adjustment of IF frequency and crystal oscillator frequency.
- Powered by 12V. The PCB size is 71mm x 100mm. The board can be conveniently placed into a 76mm x 35mm x 100mm aluminum enclosure for use.
