[ICOM] IC-745

[Dave Martin]

Hello to all.  I'm thinking about adding filters, for cw, to a 745 I've used for SWLing. Currently the radio does not have filters in it except the basic ceramic. I'm wondering if I need to add a 9MC filter in addition to a 455KC cw filter to get the most out of the passband tuning. Icom's manual says that when both 9MC and 455KC filters are present you can narrow the passband to almost 0. The problem is that they don't say which filters are needed. Has anyone done this sort of thing with their 745? Any info will be of great help. One other question, when changing from one band to another and back to the original band the frequency always returns to the same spot, regardless of the frequency you were on before the band change. Hope that makes sense. Is this normal for the 745?  Thanks.
