- Super Check Partial Database Files
- The Super Check Partial database files provide a list of callsigns used by active contesters. The data comes from Cabrillo logs contributed by contesters themselves. Contributed logs from the past 24 months are used to create the database. These logs are combined and filtered so that they result in a fairly good (but not perfect) list. The files do not contain any QSO data, such as state, CQ zone, Maidenhead Grid Locator, etc.
The dta files can be used with CT, WriteLog, TRlog, SD, N1MM Logger, NA, Win-Test, and others
