After the log submission deadline, our autonomous Robot performs strict cross-checking. Here is what the UBN statuses mean:

• VALID: Legitimate contact. Logged Callsign and Serial Number match on both ends.
• UNIQUE: The contacted callsign appears only once across all submitted logs in the database. This is usually indicative of a typo in the callsign.
• BUSTED: Fatal error. You incorrectly logged the other station's callsign, or the serial number you logged does not match what they sent.
• NIL (Not In Log): You claimed a contact with a station, but that station does not have your callsign in their log.

• Log Format: Cabrillo format only. No paper logs.
• Deadline: All logs must be uploaded within 7 days after the contest ends. Late logs will be treated as Checklog.
• Self-spotting is allowed.
• Time difference tolerance between logs is 15 minutes.
• Only one transmitted signal is allowed per band at any time.
• The YB DX Contest Committee decisions are absolute and final.
