If there was a problem with the VCO, it wouldn't change freq with the can. You can test the varactor by connecting a 10k resistor to ground at TP1. It will cut the varactor voltage in half and you should see a freq change that way too.

edit: posted too late, your post just came through
Right you are good sir, glad to have you on my side.

  • @ ShadowDelaware:
    Hambones the entire amp section would have to be retuned, and the rf transformers re wrapped.
