26.965MHz-27.405MHz 5W POTATO AM Transceiver Kit Shortwave Transceiver CB Radio Kit with Hand Mic
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:
The Potato Transceiver Kit has been updated to operate within the frequency range of 26.965 MHz - 27.405 MHz. Originally developed by our store, this kit is designed for entry-level shortwave enthusiasts.
Features:
* It uses the STC8H1K17 microcontroller as the main control, with a built-in PLL local oscillator. It includes a frequency display circuit (using a 7-segment LED digital tube, displaying units of 1 kHz; the photo has color differences, but the actual display is red). The operating frequency covers 26.965-27.405 MHz and supports AM mode.
* The reception uses a single-conversion circuit, with the TA2003 serving as the receiving mixer, intermediate frequency amplifier, and AM detector. The output audio signal is adjusted in volume by a digital potentiometer and then amplified by the LM386.
* The transmission employs Class E amplification, delivering 5W (average power).
* A relay is used for transmit/receive switching.
* Original code by our store. It includes an onboard digital control volume potentiometer, supports configuration auto-save, allows calibration of the intermediate frequency, and supports crystal oscillator frequency calibration.
* Powered by 12V. The PCB size is 71 mm x 100 mm, and it can be conveniently placed into a 76 mm x 35 mm x 100 mm aluminum enclosure for use.
* This kit includes a hand microphone.
