Re: Reasonable call prefilter

You may also want to add unique = 3 to your filter.
This makes sure that the call is heard at least three nodes.
Sounds simplistic, but if only one skimmer copies WC2L, then it will not be sent to your system.
It can be as simple as SET DX FILTER NOT SKIMBUSTED AND UNIQUE=3

Here's the RBN? definition of the difference between SKIMVALID and NOT SKIMBUSTED:
?
"Skimvalid looks back to see if there are two or more spots of the same call, on the same frequency (+/- 0.2 KHz) before marking the spot as "Valid". Obviously, that will help with single busts. Skimbusted works by looking back to see if there is a similar but different spot, already determined to be Valid and posted on the same frequency (+/- 0.1 KHz). A similar call is one that can be transformed into the new call by character insertion, deletion, or substitution."

In practice, I use NOT SKIMBUSTED because it is is faster - often I get to the spot before the station has even finished CQing. In the long run, I spend less wasted time in established pileups and the occasional busted call is just one wasted click.
