[Elecraft] K3 Filter Plots

[Jack Smith]

Jerry:

I've not seen any setup corruption from the K3 Filter program, but I 
have not tried all my K3's functions after running the filter program.

I hope to add a web page with some details on how to use the filter 
program, but my project list is expanding faster than the  time 
available to complete them, so I can't promise it will be done soon.
