Realizing I'm going "where angels fear to tread"; I'll start taking a look at wx_fill_data. I have a bit of spare time now that I'm in my new job and settling down. But, it will probably still be a while before I have anything useful to show.
I'm also gonna check w/Davis and see if they have a copy of that APRS routine for the WMII. Clay N7QNM > Thanks Tom, the patch worked, and the data is coming into Xastir as > expected.
