the government was under increasing pressure from businesses and amateurs, both to introduce higher power broadcasting in australia and to relax licensing requirements for wireless experimenters. a way forward with high power broadcasting was problematic with the interests of numerous parties, particularly awa, to be considered. the wireless regulations failed to address these but enabled ready broadcasting by wireless experimenters as an interim measure. during 1922 and 1923, a large number of experimenters were licensed and commenced to provide low power broadcasting to their local area. this partly satisfied the public's appetite for broadcasting, with the newspapers of the day carrying extensive coverage of the wireless boom taking place in the us and elsewhere. a number of amateurs commenced broadcasting music in 1920 and 1921. these included 2cm, sydney; 2yg, sydney; 2xy, newcastle; 3me, melbourne; 3dp, melbourne; 4cm, brisbane; 4ae, brisbane; 4ch, brisbane; 5ac, adelaide; 5ad, adelaide (not associated with 5ad which commenced in 1930); 5bg, adelaide; 7aa, hobart; 7ab, hobart. many other amateurs soon followed.
