hi! I want to know that the relationship between the real REF input and the rf I set in the code. thank u!!!!

The setrf(ref frequency) should be set to the REF frequency, in Hz. so if you use a 10 Mhz reference frequency, then set this to 10000000UL (unsigned long).

sets the reference frequency to 10 Mhz if ( vfo.setrf(10000000UL) == 0 )

sets the reference frequency sets the incoming reference frequency to the ADF4351 chip, based on your OXCO or other freqeuncy reference source value. Checks for min and max settings @param f reference frequency @return success (True or False)

int setrf(uint32_t f) ;  // set reference freq`
