K1OSM HAM
✅ Available for a vanity request — K1OSM was last held in the 1990s (license expired Dec 22, 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.
1x3 call: Technician, General, Advanced and 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
K1OSM 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.
Seen Sep 9, 1993 → Oct 27, 1996 · 7 discs K1OSM
· Amateur Extra · issued Dec 22, 1992, expires Dec 22, 2002
