The most distant Australian MW radio station transmitter from Fish Hoek, South Africa is 4TI Thursday Island, Queensland on 1062 kHz (a distance of 7 640 miles / 12 296 kilometres).
The 2 kw signal made it through to Fish Hoek on the 21st March 2006 at 1918 UTC with a dramatic on-location report of cyclone damage in Innisfail. Station identification was heard at 1929 UTC as "ABC Far North" (heard via the FRG7 and 160 metre BOG).
Communications Officer, ABC Transmission Public Relations, Jo Lindsay kindly responded to my reception report with a detailed email verification.
