CADA (call sign: 2ONE) is a music radio station based in outer Sydney, Australia, but licensed to Katoomba.

[2] 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 new frequency, 1476 kHz, enabled programmers to extend the audience reach to Penrith, and draw revenue from businesses in the area.

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 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).

[6] Although licensed to Katoomba/Blue Mountains/Penrith, its signal, at 5 kW located at Wentworth Falls, is enough to cover most of the Sydney basin subject to local interference.

[8] To coincide with the new look, The Edge unveiled a new brand and logo to emphasise its place as the Hip Hop and R'n'B radio station.

While the previous tagline of "Live Sexy" described the lifestyle associated with The Edge, the new philosophy of "Hits That Move You" was believed to direct listeners to what they will hear on the station.

"[15] CADA will provide a new avenue for both local and international Hip Hop and R'n'B artists to showcase their music on a station with national multi-platform reach.
