Vanity availability

Unknown

Status unknown

No vanity-slot record on file for W0JU. Either it has never been issued, is currently held by an active license, or hasn't been re-computed since its last freeing event.

Vanity availability dates are computed from FCC §97.19's hold periods: 2 years from the cancellation date for cancelled or terminated licenses, 4 years from the expiration date for expired licenses (2-year renewal grace + 2-year hold).
