. 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.
