[aprssig] Filter question help

[David Huff]

I am trying to setup a filter for my UI-view station, and looking for a
little help. 
I am trying to get only the NWS objects near me, if I use the "filter
t/n" I will get EVERY NWS object.  If I use the budlist "b/K0DMX" I get
the positions but not NWS warnings.  Anybody out there have any ideas?
Hopefully when I get this filter set right, I will gate only those
objects Inet to RF.
