2KA

2KA was an Australian radio station, licensed to Katoomba, New South Wales, and serving the Blue Mountains area of western Sydney. It was launched on 7 September 1935.

In December 1937 the station moved from 1160kHz to 780kHz. A repeater station on 1480 kHz was added in 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.
