You can piddle around with the value of the .01 capacitor between the
emitter of Q2
and the inductor to change the filter center frequency. If you want a
sharper filter,
you can raise the value of the resistor across the inductor or lower it for
a broader filter. There are several places on the web where you can get a
schematic if you need one. .gif, .jpg, .ps,  etc.
