How can you measure what frequency your radio is on?

Foundations of Amateur Radio The frequency you listen and transmit on in a
modern radio is derived from a crystal master oscillator, in my case 22.625
MHz. That master frequency is multiplied and divided to determine the final
frequency.

Not with PLL.


No, the article is accurate. With a PLL, the master oscillator is
divided (and sometimes multiplied) to provide a reference frequency for
the PLL. The final output frequency is dependent on that reference
frequency.
