📖 In the printed callbooks since 1977 as WB5UZP, before the FCC's online records

Callbook Records, 1993–2003
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.
Address history
From FCC database snapshots (2004 → now). "Seen" dates are the first and last snapshot showing that address.
NN4Z 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.

📡 On the Air: APRS, Digital & WSPR Spots

No APRS positions, PSK Reporter reports or WSPR spots for NN4Z in the last 24 hours. They show up here within seconds of NN4Z beaconing on APRS, being heard on FT8, FT4 and other digital modes, or sending a WSPR beacon.
