What a relief to find this topic. I noticed this noise friday eve. It sounds similar to the drone of a microlight aircraft. I timed it running for 5 minutes, with a spin up and spin down followed by a rest period and then repeats.
At 3:30am I was driving around trying to find the source...its not the mill which emits a white noise...i ended up at Cape Brick which has a loud vibrator but the noise is not a long drone and they have been running for years according to shift worker. Any clues, railyard, docks? -- You received this message because you are subscribed to the Google Groups "The Observatory Neighbourhood watch" group.
