[Elecraft] Origin of 8-pole Filter Plots

[Mike Downs]

Does anyone know how the 8-pole filter plots on Elecraft's web site were generated? Are they from a test jig in a laboratory setting, or are they from crystals filters that were installed in a K3 when they were tested? If they were tested in a K3 what test setup/protocol was used to generate the plots? Thanks in advance for any insight that can be offered.
