Dear all,

 

In the "Roofing Filter Notes from Wayne and Eric" link on the Order page I
see the two sentences: "Add narrower/wider filters as you prefer. I like to
use the 1.0 kHz crystal filter when tuning a crowded band or listening to a
pile up."

 

Can anyone point me to a place that can tell me what "the 1.0 kHz crystal
filter" is, where to obtain one and when it is worth using?
