[Elecraft] K3 LoCut/HiCut

[n6lrv at cox.net]

Would someone please explain the purpose and function of the low cut and high cut controls on the K3? There doesn't seem to be any explanation I can find in the current user's manual and I'd like to make sure I'm understanding their function correctly because the response I see on the P3 passband icon contridicts what I expected to see occur when increasing or decreasing either setting. Thanks very much.
