the arc server filters the spots to other nodes???  and you said before that there is some kind of mode filter outside of contests...  how can i get the complete unfiltered rbn feed both in and out of contests??

The reason for the RBN's transmission of duplicate spots is simply to 
permit users to make their own decisions about which spots to use. Both 
of the RBN Telnet servers provide filtering by spotter location, and the 
ARC server employs a "Unique>2" filter that does not forward a spot 
unless at least 3 Skimmers have heard it; taken together with spotter 
location, this seems to work well to keep the volume actually arriving 
at the user's computer to a manageable level.

> The CQ only spots from VE7CC are partially filtered to remove duplicates. You will never see a spot for the same station twice in a row. This is the most common type of duplicate the RBN sends out. VE7CC's Skimmer spots are intended to provide complete coverage without requiring user's computers to do all the duplicate filtering.
