    Circuit that would meet this requirement.
    . A radio needs to be tuned to a range of values between 526.5 -
    1606.5 kHz. Choose a combination of inductor and variable
    capacitor values within a tuned circuit that would meet this
    requirement. Choose practical components from standard vendor
    web sites (e.g. Maplin/RS) if possible and provide full item
    description.

    I have done the working out but I'm not sure if its correct.

    L = 100uH

    XI = 6.28*526.5*10ᶺ3*100*10 ᶺ-6=

    330.642 Ohms = Xc

    C = 1/6 .28*F*Xc =

    1/6.28*526.5*10 ᶺ 3*330.642 = 0.00091uF

    = 910 pF. at 526.5kHz

    XI = 6.28*1606.5 ᶺ10 ᶺ3*100*10 ᶺ-6=

    1,009.4 Ohms = Xc

    C = 1/ (6.28*1606.5*10 ᶺ 3*100*10 ᶺ -6) =

    9.9*10 ᶺ-4 uF = 990 Pf

    C = 910 pF to 990 pF.
