Was bored today so decided to scan the upper freqs on my scanner.
Found some voice on 1004.2875 and 1004.0625.
ACA says it belongs to the Dept of Defense, but the transmissions i heard sounded more like a bus company that drives to the airport etc.
With regards to my posting re:Transfield.......they transport defence personnell and logistics all over WA.....in fact all over Australia......it is quite concievable that they will go past the airport or have an office there....as I said.....just a suggestion...Nick
The Dept of Defense have freqs from 1002.000Mhz to 1006.990MHz all used fron time to time.
Last heard range data on 1005.252MHz from Gingin to LANCELIN Control
