...I have a great problem with AM-Breaktrough and I have to switch to 8kHz ZF-Shift. So most of my operation time my KXFL3 is not in use :-(

An: "Phil Hystad" <phys...@mac.com> Cc: "Elecraft List" <Elecraft@mailman.qth.net> If all of your operating is casual chatting, on uncrowded bands, with poor antennas, then the KXFL3 won't do much at all for you. Its primary function is to prevent DSP overload from very strong, adjacent signals and you won't experience that much if at all. If much of your operating is serious DXing or contesting on crowded bands with good antennas and active nearby neighbor stations, you will often encounter those strong, close-in signals and the KXFL3 will help a lot. Somewhere between those extremes of strength and crowding is the threshold. I got the filter even though it is often unnecessary. /Rick N6XI On Thu, Apr 10, 2014 at 7:56 AM, Phil Hystad <phys...@mac.com> wrote: > I have a curiosity question.
