K6ISI HAM

✅ Never issued — K6ISI isn't in the FCC's public license data (which starts in 1999) or the 1993–2003 callbooks, and nothing in it blocks a vanity request. Calls like this are usually granted when requested.

1x3 call: Technician, General, Advanced and Amateur Extra licensees can request it. No pending applications list it.
Last requested Sep 4, 2012 as choice 3: not granted, that applicant got K2ISI instead.

The FCC has no record of K6ISI ever being issued.

K6ISI 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.
