Another possibility:

If the filters are easily switchable from position to position, try
swapping a couple and see if the fault follows the filter or remains

Thanks, Guys - these are fine ideas. I checked inside last night; the
filter in question is hard-soldered into the CB; if it were just
inserted, I guess I could have just plopped another similar filter I
have (15 kHz) into place to try it out.

I've also already spoken with Kiwa, and this morning I'll give Icom a
call.
