I am still fiddling with the 570 and I may have to do the unthinkable and
hunt up the book. When I go to menu 46 and select no filter I can still hit
the filter button and change the band width. When I select the filter
option in menu 46 and hit the dreaded filter button absolutely nothing seems
to change. Either there is a problem with the cw filter which is doubtful
or I'm leaving out a very basic step.
