KD4JAJ HAM
✅ Available for a vanity request — KD4JAJ was last held in the 1990s (license expired Jan 21, 2002), 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.
Held Before 1999
KD4JAJ 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.
