AB5SQ HAM

✅ Available for a vanity request — AB5SQ was last held in the 1990s (license expired Jan 25, 2004), before the FCC's online records begin, so the two-year wait is long over. Confirm in the FCC's vanity system before applying.
2x2 call: only Amateur Extra licensees can request it. No pending applications list it.

Not in the FCC's online records (1999 → now), but held before then: see below.

Held Before 1999

AB5SQ in the 1993–2003 Callbooks
From the FCC amateur database as published on the QRZ! callsign CD-ROMs, 1993–2003, before and alongside the FCC's online records (which start in 1999). "Seen" dates are the first and last disc showing that record; the issue date is the FCC's, so it can be a renewal of an even older license.
