In the ladder filter that Tentec uses, the crystal frequencies determine
the center frequency, while the capacitors determine the bandwidth. The
larger the capacitors, the smaller the bandwidth. There can be a little
shuffling of crystal frequency to refine the filter response curve.
151 is 150 pf
360 is 36 pf
510 is 51 pf
271 is 270 pf
