Solar activity continues to drop - good 11 MHz signals

As at March 17 2011, the 10.7 cm solar flux had dropped to 95, and the daily
SSN to 41. These are very low levels, even though solar cycle 24 is
progressing slowly!

So not much action above 12 MHz for multi-hop long-haul transmissions over
darkness paths.

I did some research in the 11 MHz band yesterday in the Warrandyte State
Park, 30 mins from here, 20 km east of central Melbourne. This was at the
eastern end of the Pound Bend Picnic area, next to the Yarra. The Eton E5
and a 3 m random antenna yielded many signals in the mid afternoon window,
0430 to 0500, with longpath dominating from Europe, Africa, and the Middle
East and shortpath from Asia and the Americas.
