NR4BT HAM

✅ Never issued — NR4BT 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.
2x2 call: Advanced and Amateur Extra licensees can request it. No pending applications list it.
Last requested Apr 3, 2018 as choice 2: not granted, that applicant got KR4BIT instead.
The FCC has no record of NR4BT ever being issued.
