[Yaesu] Difference between Yaesu YF and XF Filter markings ?

[Richard G3XVF]

Hello All,

I have just bought new the following Yaesu Filters,
does anyone know why Yaesu optional filters are advertised in catalogue
with the first two characters starting with  YF  these letters are also on the filter
boxes,  but the top of the filters are marked with XF are the specifications
the same for both filters or are they designed for different transceivers ?

YF-144SN    filter marked    XF-114SN
YF-114CN          "              XF-114CN
YF-110SN          "              XF- 110SN
YF-110CN          "              XF- 110CN
YF-115C            "               XF-115C


Thanks,

73 Richard G3XVF
