N4DXM HAM

✅ Available for a vanity request — N4DXM was last held in the 1990s (license expired Feb 11, 1996), before the FCC's online records begin, so the two-year wait is long over. Confirm in the FCC's vanity system before applying.
1x3 call: Technician, General, Advanced and Amateur Extra licensees can request it. 1 pending application already lists it (first filed Oct 14, 2026) — see requests.

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

Held Before 1999

N4DXM 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.
N4DXM 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.
