Forgot to add, I have the Murata CFJ455K5 from a TS 830 for sale also. It fits any of the Kenwood 455 IF slots where the ceramic filter goes and it has somewhat narrower bandwidth than most, I believe it is at 2.4 KHz for the 3 db points (rather than the wider K12's at 2.7 KHz). I'd like 20ドル to ship this in the US. Clark WA3JPG
