TERRY,

If these Murata 455 Ceramic Filters interest you, then you may
wish to take a look at this replacement for a 455 kHz IF Filter.

"Channel Guard" RX 455 kHz IF Filter.

* The 455 KHz version is an ultra narrow, 3-pole ceramic filter that
replaces the existing (and broader) 1-pole Murata ceramic filter. (It's
that small black or gray plastic cube soldered into the main CB
chassis.) Just unsolder the old filter, install the 3 CHANNEL GUARD
bare wires into the corresponding empty INPUT/OUTPUT/GROUND holes, and
connect to +8-13 VDC. You are done!
