Call signs in Antarctica

Call signs may also be issued by a local Antarctic authority (i.e. base commander) who chooses from a block reserved by their national body for that purpose.

[citation needed] The International Telecommunication Union does not assign call letter blocks to Antarctica[5] since there is no single government there which can send delegates to ITU conferences.

[6] In some cases the assignment of call letters is made locally at an Antarctic base and the relevant national body is notified.

The Worldwide Antarctic Program keeps a list of special event call signs issued from various countries at various times.
