All:

Thanks to everyone who responded to my question regarding crystal filter 
shape factors for the K3S. The plots shown on the Elecraft website are a 
bit fuzzy for my eyes, but I did find the list shown below from a post 
in 2008.

I'm assuming the shape factors are the same for the current batch of 
filters?
