The FL54 is a 455khz ,270hz filter. However all the places I have looked, I do not see a mention of the FL54. The narrow filter is always FL53a at 250hz..

The FL53a works in the IC 775,765,738,736,737,718,707,and 703. But I dont know about the FL54.

Does anyone know if the FL54 works in any of the rigs above but expecially the IC 718?

I found the answer to my question. The FL54 is: FL54 ICOM CLOSEOUT 270 HZ 9.0115MHz CW FILTER FOR IC740 OR 745. As a result it cannot be used in a IC 718 as a 455khz filter
