My question is how long does it take to measure 8270.01953125 Hz? Based on my experience, it seems that it would take more than 3 years. Where am I going wrong. consider a "hardware" example: you ca

You don't need anything like 3 years, perhaps only a few seconds. It all depends on having enough S/N ratio, and knowing in advance that you're dealing with a monochromatic sinusoid. Now if you wante

It is good to know the frequency to within 1uHz for VLF amateur radio. A 1uHz error amounts to a 30 degree phase error after one day, enough to significantly affect the stacking of repeats. Fortunate
