It is now official - Summer has ended and Autumn has commenced!
On the last day of Summer, February 28 2011, I did some propagation research in the 11 MHz band during our Melbourne early afternoon period, with plenty of longpath (darkness) activity from Europe, Africa, and the Middle East, and shortpath from the Americas and Asia.
In fact, there was evidence of multi-path propagation, which occurs during our early Autumn.
This is a summary of key occupancies as monitored from one of my favourite field sites on the Warrandyte State Park, about 20 km from central Melbourne, between 0330 and 0400 using the Eton E5 and a 3m random antenna tossed into a scrubby tree, not far from the Yarra River!

Note: Arnie Coro, Technical Manager of Radio Habana Cuba, has asked me whether there is any propagation from Cuba into Melbourne during this time window on 11 MHz - only two outlets noted on this occasion - 11760 (almost buried under co-channel China), and 12010).
Regards from Melbourne!
