✅ Available for a vanity request — KA1ESF was last held in the 1990s (license expired May 5, 1997), before the FCC's online records begin, so the two-year wait is long over. Confirm in the FCC's vanity system before applying.
2x3 call: any licensee can request it.
No pending applications list it.
Not in the FCC's online records (1999 → now), but held before then: see below.

KA1ESF 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.

KA1ESF in the Printed Callbooks, 1909–1997
From scanned copies of the printed callbooks (government lists from 1913, then the Radio Amateur Callbook to 1997), read by OCR, so names and streets can carry typos. Each line is one or more editions in a row showing the same name at the same address.
