Premise: ABC Western Victoria (call sign: 3WV) is an ABC Local Radio station in the Wimmera region of Victoria, Australia. Its primary transmitter is located in Horsham which broadcasts on 594 kHz AM. The station is clearly receivable over most of western Victoria, well beyond the Wimmera. In the past, it was designed to serve this broader region.
