I also noticed Melbourne Centre frequency out that way has changed as well from 125.7 to 132.32. Anyone know why? Is there some sort of magnetic interference out that way on the lower frequencies?
That changed late last year by NOTAM to
134.325.
RAPAC were informed that at Mt Macedon there is a lot of transmitting equipment operating on a wide variety of frequencies. Interference was occurring to 125.7 when certain combinations of the other equipment were transmitting. 132.325 was selected as a frequency not affected by any combination of transmitters.
