Hi Andrey
already with the synthesizer in operation when I want to calibrate the SI 5131 using the option in the corresponding menu when pressing the VFO key it returns to the menu without being able to calibrate.
Am I making a mistake or skipping a step?
in the link is a video showing the problem

thanks

Try next modification in module menu.h
Code:
void ShowSiCalibrationMenu()
{
  const char* MenuItems[] = {NULL};
...............
...............
...............
#ifdef VFO_SI570
  vfo570.out_calibrate_freq();
#endif
  while (keypad.Read() != cmdNone) ; // <<--- insert this line
  while (keypad.Read() == cmdNone) ;
}

You need measure frequency at Si5351/Si570 output and write measured values in config_hw.h here:
Code:
#define SI5351_CALIBRATION       26000000
#define SI5351_2_CALIBRATION     26000000
#define SI570_CALIBRATION        56319832
