In winter, we don't usually get the temperatures necessary to produce inversions which create tropospheric ducting conditions that can carry #2mSSB #hamradio signals further than my 80km radio horizon. There's almost always some jets queueing to land at SYD which cross the radio path between me and Canberra. which produce very brief band openings over this 220km path.
