N4PTU callsign genealogy

Currently held by MUSE, EDWARD I

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 N4PTU's current licensee, walking backwards.

The current licensee has not held any other callsign on record.

Successor callsigns

Callsigns held now by people who previously held N4PTU.
