Hi Larry, The XFIL control rotates through the roofing filters. When you manually select a filter, its default center and passband are used. This is described on p5 of the Owner's Manual.
Try reading the section "Filter Presets (I/II)", to understand the I and II filter presets, and how they operate. You can also use NORM 1 and NORM 2, desribed in the "Filter Normalization" section. Any of these methods allow customization on a per-mode bases while you're operating. In a way, XFIL is a holdover from the K2. It does allow changing the filter in use, but it just changes to the default center and passband for that filter. 73, matt Matt Zilmer, W6NIA www.elecraft.com 831-763-4211 x129 Skype: matt.zilmer On Sat, 11 Jan 2014 12:39:57 +0000, you wrote: > >Please excuse me people because I am very new to the Elecraft world.
