CW QRP Shortwave Radio Kit - CW Transceiver Shortwave Radio Kit

The patch device of the main control board has been pre welded and connected to the base plate in the form of stamp hole. The single chip microcomputer adopts pic16f1938, builtin PLL local oscillator, supports crystal oscillator calibration setting, and has its own frequency indication circuit (Seven Segment LED nixie tube is used, the display unit is 1kHz, the photo has color difference, and the actual color is red. The working frequency covers 7.000-7.100mhz, 1kHz or 100Hz steps )..
Ta2003 mixer is used for reception, and crystal filter is used for if. After ta2003 multiplication detection, the sound size is adjusted by digital potentiometer and sent to audio active filter circuit. Finally, LM386 drives speaker, and if frequency supports calibration setting..
Use 3 bs170 parallel outputs, class E amplification, 12V power supply, output power 5W! Relay switching is used for transceiver, with the function of transmitting delay adjustment to avoid frequent relay switching and improve the isolation of transceiver channel..
It has the function of automatically sending call signs, which is very convenient to use. The MCU uses the original code of our store, which can adjust the code speed, sidetone frequency and sidetone size. It can input the call sign by ....
