 Telecom Tower, a broadcasting facility atop Black Mountain opened on 15 May 1980 and quickly became a major Canberra landmark.A vital link for television and telephone connections between Sydney and Melbourne, the tower also became the transmission site for CTC's primary VHF 7 signal alongside ABC on VHF 3 and ABC FM 101.9.CTC's original studio building was demolished to make way for the tower and the station produced a 12-minute film on the construction of Telecom Tower which was shown at the visitor's centre.
