[Elecraft] [K3] Noise Clicks...still!

I've always found that if you have a loud CW signal present, and you start narrowing down the passband width just adjacent to them, you get clicks.. That's just codes little way of knocking at the door of the filter... Until you get narrow enough, or far enough away from their transmission your going to hear them.  If the signal is an S4 of S5 you probably wont here them nearly as close as say someone at S9 or 20 over S9.  That's what I've found anyhow.  This has ALWAYS been the case.  Perhaps it has something to do with the fact I have Filters in my rig, and not just depending on the DSP???
