AM detector in SPICE

Here I am using 100 MHz. The sim is slow.

I changed it to 10 MHz and it sped things up a bit. So click the link and adjust the components, even remove some to see the results. I used the values from Morgan's book for boys. Simply short or remove the parts declared to be unnecessary and see the effects.

I used LTspiceIV it will work in later versions. Look at L1, C2 and C3 voltage and current. These reading will explain a lot about what is happening in the circuit.
