[Yaesu] Filter

[NICK.WALLACE]

Hi All, 

I find the nos. on the yaesu filters confusing regarding which radios they go in etc.  Can someone please help with the filter XF 8.2M 202 01. Google didn't help me a lot this time. I think it is for the FT1000 which i have . The only extra filter i have in there is the narrow ssb one. Will this other filter work in cascade with the cw filters that are already in there?

TIA
