Here are a few charts from VK4 to DL, OH, JA, W6 and W2 in August this year.
As you see I do not expect too much for EU and East coast of NA. In Sept 2010 I operated JA1NLX/VK4 at Dunk Island, OC-171. I found very limited opening for EU around 17z on 14MHz and almost no opening for NA. The location was not good for NA though.
Your comment and advise will be very much appreciated.
