    Isn't a direct path for DC through the inductor?

    Hello,

    Yes, you are right.
    All current wil flow through the inductor.
    A capacitor between the varicap and the tuned circuit will solve the problem.
    The value of the capacitor will influence the total capacity of the combination.
    The total value will be the capacitor in series with the varicap capacitance.
