[Elecraft] KXFL3 - How to Use It

[Walter Underwood]

It is automatically switched in as the passband width is narrowed. The XFIL icons on the display show which filters are in use.

It won’t change anything inside the passband, but if strong signals outside the passband are causing problems, it will reduce them.

Search for “xfil” or “roofing filters” in the KX3 manual.
