K4CYX HAM

✅ Never issued — K4CYX 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 11, 2003 as choice 4: not granted, that applicant got K1MAE instead.
The FCC has no record of K4CYX ever being issued.
K4CYX 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.
