I hope I'm not hijacking this post, but I am seeing what I'd consider "strange position reports".

What I see here is that several station icons are grouped around (but strangely not on top of) a digipeater's (W7MOT-3) location atop the White Tank Mtns, west of town. There, I see my N7UV-5 icon, my ARSTRA icon, and the KE7NEA-1 icon.?
This is a frequent issue, and I never resolved it myself, and perhaps that's why I wasn't using YAAC. In other s/w, like APRSIS32, and certainly in the aprs.fi server, the positions for these stations are shown correctly, so it seems to be an interpretation issue for YAAC, not a fundamental problem with the location packet.
Any ideas? I searched the listserv and this was the only msg that seemed to fit.
