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?
