I've been breadboarding.

Using a 1MHz square-wave signal generator with a 50Ω output, I'm using the LC values as shown and find that the sine wave output peaks at about 850KHz. Obviously I want to adjust the LC network to bring the maximum output nearer 1MHz, I wonder if anyone knows the magic dot command to allow me to sweep the network in LTspice to view the output and get a closer approximation?
