Posted: 25 Nov 2017 09:00 AM PST 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. -- ================== Remove the "x" from my email address Jerry Stuckle ================== |
