It is the flagship station in the ABC Local Radio network and broadcasts on 702 kHz on the AM dial.

The station transmits with a power (CMF) of 3,110V, which is equivalent to 50 kW (the maximum permissible in Australia) from a site 30 kilometres (19 mi) west of the Sydney CBD.

[1] Its first callsign was 2SB where 2 denotes the State of New South Wales and SB stood for Sydney Broadcasters Limited.

In 1963, it swapped formats with 2FC and assumed that station's old role as flagship of the Interstate Programme, which eventually evolved into Local Radio.

[14] Mornings with Sarah Macdonald was the first program to broadcast from Parramatta after the facility was officially opened by Kim Williams, David Anderson and Andrew Charlton.
