[1000mp] Filter Identification

[Jim Gerke]

Larry,

In the case of the YF-115C, the filter itself is the XF-115C. The entire plug-in
PCB assembly with the filter mounted on it is the YF-115C. Confusing, eh?

Even worse, they (Yaesu) aren't even consistent. For example, the Yaesu filters
used in their FT-817/857/897 are labled XF-119S (SSB) or XF-119C (CW) but the
plug-in assemblies are called YF-122S and YF-122C!
