[TenTec] Values of filter capacitors?

[John Lockhart]

Hi Tom,

Aren't the crystal frequencies in the CW filters much different than those
in the SSB filter?  I always thought that the crystal frequencies were the
main determinants of the bandwidth.

The spare 217 filter here has 8 crystals and a ceramic disc capacitor on
each end (coupling cap?) labeled "151J N750".  Moving in from one end to the
other, the ceramic disc caps are labeled 360, 510, 271 in parallel with 271,
271 in parallel with 271, 271 in parallel with 271, 510 and 360 (all N750).

73,

John W0DC
