There was a software problem with the announcement. The database
actually contains 175333 master callsigns.
This list used to contain over 230K callsigns:
http://dx4win.ad1c.us/data/calldata.html#Master
Club Log was using an inadequate filter which allowed many busted
callsigns to "make the cut". Now, a callsign must appear in the Club
Log database at least 40 times, previously it only required 20 QSOs.
The Club Log "super check partial" database also contained a few dozen
duplicate calls, which have now since been eliminated, once I reported
the problem. Finally, my software eliminated another 8K of bad
callsigns which it determined through several different heuristics.
The new list is much cleaner now.
