The www.HAMRADIOGUIDE.net team has developed (with a little 'hard work) an updated table that shows all the information related to amateur radio prefixes. In particular, they have been cataloged all prefixes amateur ITU and non-ITU that we were able to collect the scores and ranking of most wanted in January 2017. For most of prefixes we have classified as "aliases", or the alternative prefixes always official. The table is available on the website under WWW.HAMRADIOGUIDE.NET Hampedia.
