It's probably those Chinese long-range cordless phones that operate right in the 2-meter satellite sub-band..... unfortunately, thanks to eBay, they are even popping up here in the States, where they are illegal to even import, let alone sell.

Here is a 2 minute audio clip from the second pass over Australia which I mention in my previous post. Shortly after the start, when the signal gets near full quieting you can hear a tick-tick-tick sound repeated at regular intervals, followed by other random noises. My call can just be heard among the hash.
