POTATO Shortwave PLL AM Transceiver Kit CW Transceiver Telegraph Radio DIY10M

Description: Potato POTATO shortwave AM transceiver kit walkie talkie 10 meter radio amplitude modulation radio CB machine NOTE : the item is diy kit All kits in our store require buyers to complete welding and debugging themselves; The installation of B kit carries risks. Buyers should evaluate their technical level and instrument equipment correctly to avoid unsuccessful kit installation and adjustment; The C kit manual (electronic version) needs to be downloaded from the online storage and obtained from the store owner after purchasing the kit; Due to malicious plagiarism, the kit does not provide circuit diagrams for pre soldered modules, nor does it provide source code or firmware for microcontrollers; The E-kit is shipped with scattered electronic components. The finished product pictures displayed in our store are for reference only when purchasing; If there are missing parts in the F kit, please do not panic. Contact our store and we will send a replacement after verification. The kit was originally developed by our store and is designed for beginner shortwave enthusiasts to get started. It has the following features: 1. Using STC8H1K17 microcontroller as the main control, with built-in PLL local oscillator and built-in frequency indicator circuit (using seven segment LED digital tubes, display unit is 1KHz, photo has color difference, actual color is red), working frequency covers 28.400-29.300MHz, supports AM mode. 2. The reception adopts a frequency conversion circuit, with TA2003 performing reception mixing, intermediate amplifier, and AM detection. The output audio signal is adjusted by a digital potentiometer to adjust the sound size, and then sent to LM386 for amplification. 3. The transmission adopts Class E amplification with an average power of 5W. 4. Relay switching is used for transmitting and receiving, and the machine is equipped with a microphone. 5. Our original code, onboard CNC volume potentiometer, supports automatic configuration saving, supports intermediate frequency calibration, and crystal oscillator frequency calibration. 6. Powered by 12V, with a PCB board size of 71 * 100mm, it can be easily placed in an aluminum chassis of 76 * 35 * 100mm for use. 7. This kit comes with a handheld microphone. Main indicators Power supply: 12V Working current: receiving ≈ 130mA @ 12V; Emission ≈ 1300mA @ 12V Frequency range: 28.400-29.300MHz, 10KHz/1KHz stepper Working mode: AM transceiver
