Re: [Elecraft] PLL Reference Oscillator out of spec
Mike; That is way out of spec. Make sure you all of the components installed in the correct location. Double check that you go the varactor diodes in the right location; this circuit uses two different types. Also check the DC voltage on the varactor diodes to make sure it varies from 0 to 8 volts. If everything checks out okay, ask Gary to send you a new crystal and check that one out. -John KI6WX - Original Message - From: "Mike KL7R" <[EMAIL PROTECTED]> I have completed Allignment and Test, Part II I need help with the PLL Reference Oscillator Range Test: Ref High Freq 12098.1 Ref Low Freq 12092.56 Range (kHz) 6.35 Which is out of spec.
