CADA (call sign: 2ONE) is a music radio station based in outer Sydney, Australia, but licensed to Katoomba. It is operated by the Australian Radio Network. History CADA, formerly known as The Edge, is an Australian radio station licensed to Katoomba, New South Wales, and serving the Blue Mountains area of western Sydney. The radio station was launched on 7 September 1935, as 2KA. In December 1937, 2KA moved from 1160 kHz to 780 kHz. A repeater station on 1480 kHz was added in 1978. From November 1978, the station transmitted on 783 kHz on the AM band, with a translator station on 1476 kHz at Emu Plains. Before the station launched its Emu Plains based translator in the late 1970s, it was exclusively a Blue Mountains based licence. The new frequency, 1476 kHz, enabled programmers to extend the audience reach to Penrith, and draw revenue from businesses in the area. To combat the potential damage to their Sydney audiences at the time, a number of Sydney radio stations bought the licence and experimented with various automated technologies, none of which were seriously designed to draw mass audiences. Australian television personality Mike Walsh bought the licence in 1983 and worked to advance his vision of developing a successful business model and innovative entertainment product. The station, which had been broadcasting from a studio in Borec House, at the corner of Station Street and Henry Street in Penrith, developed a new studio at the intersection of Henry and Lawson Streets. It adjoined a cinema complex, which was also owned by Walsh. The Edge 96.ONE On 26 October 1990 at 13:00 hrs., it converted to the FM band and became One FM, and later 96.1FM. The station had paid just $46,000 dollars to convert to the FM band, which was considered a bargain, noting it covered a considerable area of Sydney, and the record amounts of money being paid by other AM stations to convert to FM. In order to be granted the licence the owners, 'Hayden Nepean Broadcasting', had to agree to comply with regulations regarding local content and the stations overall focus on the local community. The station played Top 40 mainstream CHR (1990–1997, 1999–2005) and Alternative Rock (1998) before its Dance, Hip Hop and R'n'B phase (2006-2022). In 1997 the station was sold by Mike Walsh to Australian Radio Network, which currently owns three Sydney radio stations: CADA, KIIS
