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.
No APRS positions, PSK Reporter reports or WSPR spots for KD4JHN in the last 24 hours. They show up here within seconds of KD4JHN beaconing on APRS, being heard on FT8, FT4 and other digital modes, or sending a WSPR beacon.
