Navigazione Generale Italiana
Wireless telegraphy was first established on Antarctica at Cape Denison, Adelie Land, in 1912 as part of the Australasian Antarctic Expedition. The callsign allocated by the PMG Department was MAL, which was a duplicate with that for the SS Liguria of the Navigazione Generale Italiana (such duplication was common prior to implementation of the 1912 London agreement).
