Special Features

  • Due to malicious plagiarism, the kit does not provide circuit diagrams of pre-soldered modules, nor does it provide microcontroller source code or firmware
  • The manual of the C suite (electronic version) needs to be downloaded from the network disk and obtained from the store owner after purchasing the suite
  • 12V power supply, the size of the PCB board is 70*100mm, which can be easily put into the aluminum case of 74*29*100mm.
  • Using STC8H1K08 microcontroller as the main control, built-in PLL local oscillator, built-in frequency indicator circuit (using a seven-segment LED digital tube, the display unit is 1KHz, the photo has color difference, the actual color is red), the operating frequency covers 7.000-7.100MHz, support CW mode, 1KHz step
  • The transmitter adopts class E amplifier circuit, 5W power output

Description

1. Use STC8H1K17 microcontroller as the main control, built-in PLL local oscillator, and built-in frequency indication circuit (using a seven-segment LED digital tube, the display unit is 1KHz, the photo has color difference, the actual color is red), the working frequency covers 28.400-29.300MHz, supports AM mode.
2. The reception uses a primary frequency conversion circuit, with TA2003 doing the receiving mixing, mid-amplification, and AM detection. The output audio signal is adjusted by a digital potentiometer to adjust the sound volume, and then sent to the LM386 for amplification.
3. The transmission adopts Class E amplification, with an average power of 5W.
4. Relay switching is used for sending and receiving, and the machine is equipped with a hand microphone.
5. Our store's original code, on-board digitally controlled volume potentiometer, supports automatic saving of configuration, supports intermediate frequency calibration, and supports crystal oscillator frequency calibration.
6. 12V power supply, PCB board size is 71*100mm, which can be easily placed into a 76*35*100mm aluminum chassis for use.
7. This kit comes with a hand microphone.
