Es Propagation in 2010

[ka5dwi]

Good Morning and Happy Canada Day,
I have been compiling 10-Meter Es activity for 6 years thanks to an ad-hoc group of Hams called PropNET; http://www.propnet.org.

Using the Central Limit Theorem of Statistics, I have produced a 5-Year study of the Spring/Summer Es season. The study will be published soon, but I have already presented key points on the PropNET Studies Blog: http://propnet-studies.blogspot.com/ The data was calculated from over 60K PropNET captures received here in the Dallas/Fort Worth Texas area from 2005-2009.

Currently, I am updating and comparing 2010 results with the averages of the 5-year study. So far it is a very good year. We have averaged about 3 to 4 more hours of Es activity every day. I am sure our continued low levels of solar activity have influenced these numbers.

I am in no way trying to explain the causes of Es, nor am I trying to say when I can QSO directly with you on 10 Meters. But what I have done is to clearly show the trends and characteristics of Es. All I can say is that Es are NOT sporadic all you have to do to max results is work with the Sun.

I update the blog every 2 weeks or sooner if need be. I will do a 2010 recap of the season by mid-September. I also invite you to view our real-time maps on the PropNET Homepage.

I always entertain comments and questions. You can post them (please be respectful) on the blog or you can Email me direct to ka5dwi at sbcglobal.net
