KA4KRM HAM
✅ Never issued — KA4KRM 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.
2x3 call: any licensee can request it.
No pending applications list it.
The FCC has no record of KA4KRM ever being issued.
KA4KRM 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.
