Can anyone identify a Yaesu 455 kHz, 2.0 kHz Crystal Filter labeled as an XF-110SN. I believe it is a 2.0 kHz 3rd IF Filter for the FT-1000 series but the current and recent listing for this filter shows it as a YF-110SN so I'm wondering if the XF-110SN is an older version. Thanks for any info! Bob Wilson - W4BW Email: contesting at w4bw.net
