Hey guys, I am thinking about adding a couple filters to my 746, I already have a 9mhz INRAD 400hz cw filter, but, was wondering if it worth it to get a 455hz slot, 400hz cw filter cascaded, and was thinking about a 9mhz, 1.9 SSB filter---is this worth the $$? I do a lot of contesting, & some DXing. 73-Chuck KI9A
