I recently had the following problem with the PLL Reference Oscillator:
When the circuit was oscillating I could see it on a scope at the source of Q19 and at the junction of RFC14 and R20. When it is oscillating (after pushing Band-) the voltage is about 1.3 volts (at RFC14 and R20) and changes to 2.6 volts when Band+ is pushed and then stops oscillating. The source of the problem turned out to be the wrong core used for RFC14. I am posting this problem and cure so that if someone else has a similar problem they will be able to find it here on the reflector with a simple search. I would like to thank Gary, AB7MY, for his help. I would imagine that Gary is such an asset to Elecraft that they reward him by bringing him to work in a stretch limousine and provide him with a scantily clad masseuse for a post lunch massage to ease the stress from dealing with morons like myself.
