Byron, Fine on all that, so far so good - next is to check L31, X1, R21, D18, C84 and C85 for good soldering, and make certain D16 and D17 are oriented correctly. If nothing is found awry, I would arbitrarily replace X1 as the first step and after than D16 and D17. Remember that this is just like a VXO circuit, no real 'magic', you add capacitance (that is what the varactors should be doing at lower voltages) and the frequency shifts downward.
