[TenTec] Values of filter capacitors?

[Dr. Gerald N. Johnson, electrical engineer]

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
