[Dxspider-support] Filtering Issues

Hi,

My node is up and running and successfully connected to wr3d (thanks to Dirk
and all others for the help I have received so far!) I am still having a
problem getting the filtering to work exactly as I would like, however. I
want to limit the spots on my cluster to just regional, so that we don't
have the whole list to look at. I figure that CQ zone 4 is a good compromise
with regard to having somewhat similar propagation characteristics. I want
to limit the list itself, so that a sh/dx only shows zone 4 spots, which is
why a default user filter would not work. Anyway, after some help from Dirk,
I was able to enter the appropriate filter into the system on my cluster:

acc/spot wr3d input by_zone 4

This seemed to reduce the spots down to North America, but was still letting
in some stations on both the west and east coasts (i.e. K1 and W6 stations,
as examples...) it seemed more like the filter was really set to accept
zones 3,4 and 5, although a sh/filter wr3d did not indicate any zone filter
but zone 4. I then tried some of the other versions of this, 

rej/spot wr3d input not by_zone 4

and adding explicit rej filters for zones 3 and 5 to the first filter, etc.
I was clearing the filter each time, but was not actually disconnecting from
wr3d each time. Finally, I executed the rcmd to install the zone 4 filter on
the wr3d end, and did not see any difference in the system behavior - I was
still getting spots that were outside of zone 4, although not from anywhere
outside of the U.S. or Canada. As a last resort, I tried setting some
specific accept filters by state. I still got California spots being
accepted even without CA being on the list of accepted states. I am assuming
I am still not doing something right here...Is this a matter of not
recycling the connect to wr3d, or recycling the system itself, or is there
some other mistake I am making?

Thanks,

KE0MF/Mike
