[Elecraft] K3 filters

[Alan Bloom]

Keith,

An 8-pole filter should have more ringing than a 5-pole filter of the
same bandwidth and ripple.  That's because the loaded Q of each pole
(crystal) is higher (bandwidth of each pole is narrower).  You can think
of it as each crystal covering 1/8 of the bandwidth rather than 1/5,
although that's an oversimplification.
