1) How do I change my username? The site owner, Mr. Lindsay Blanton, is the only person who may do this. You must email him privately at webmaster @ radioreference.com. Be ready to give a good reason why it needs to be changed. Generally usernames are changed because of an amateur radio callsign grant - or change - or you later decide your username should have not contained your true name. All else will undoubtedly be denied.
