WC0EM callsign genealogy
Currently held by Marx, Gregory G
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 WC0EM's current licensee, walking backwards.
Successor callsigns
Callsigns held now by people who previously held WC0EM.
