7-7.3MHz POPLAR Shortwave CW Transceiver Kit Telegraph Machine Shortwave Radio Station Kit for DIY
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.
Description:
This kit is originally developed by our store and is designed for beginner shortwave enthusiasts.
Key Features:
1. Advanced Microcontroller Control:
* Uses STC8H1K17 microcontroller as the main controller.
* Built-in PLL local oscillator with frequency display (7-segment LED display, unit: 100Hz, actual color: red).
* Working frequency covers 7.000-7.300MHz. It supports CW mode with 100Hz/1KHz/10KHz tuning steps.
2. Superheterodyne Receiver Circuit:
* TA2003 for receiving mixing, outputting 10.7MHz intermediate frequency to the crystal filter. Then, the signal goes to the MC3361 for multiplying detection before being amplified by the LM386.
3. E-Class Amplifier for Transmission:
* Features an E-Class amplifier circuit with 5W power output for transmission.
4. User-Friendly Design:
* Original custom code developed by our store.
* Onboard digital volume potentiometer.
* Supports automatic configuration saving, side tone frequency and volume adjustment, and crystal frequency calibration.
5. Power & Dimensions:
* 12V power supply.
* PCB size: 71mm x 100mm.
* Easily fits into a 76mm x 35mm x 100mm aluminum enclosure.
Main Specifications:
1. Operating Current:
