The FCC publishes a previous_call_sign on
every amateur license — a self-link to the licensee's prior callsign.
Following those links produces the chain below.
Previous callsigns
Older callsigns held by N3GKR's current licensee, walking backwards.
The current licensee has not held any other callsign on record.
Successor callsigns
