Synthesizer frequency Si5351 transceiver for shortwave. The development of our UT5QBC UV7QAE and colleagues.
Synthesizer of microcontroller assembled on STM32F100C8T6B, all the information is displayed on the color display size of 1.8 "
Small dimensions of the PCB (85mm x 45mm) allow its use in small constructions transceiver
Output CLK0 - frequency VFO.
