Jim, Thanks for the reply.? I understand your reasoning, but I'm just trying to understand why it doesnt work at all. Then I could worry about whether it was on frequency.? I already have a tiny SA, so I don't really need to build this, I'm just trying to get components to work that others have done before me. When Ashar Farhan builds one out of a junk box and makes it work, I wonder why I can't.? Also Wes Hayward sent me a schematic for his (similar) butler oscillator (5th overtone) with junkbox crystals and showed how the oscillator worked slightly off with just a resistor. (I built that and acheived 100 mhz).? Then he inserted the 20 MHz crystal and forced it into the correct frequency SHAPE as shown on his spectrum analyzer with the variable cap.? Again a fairly simple circuit.? However I could not get mine to oscillate with the crystals I have even though the thing will oscillate at 100 Mhz with a resistor.
Andy
