[SADXA] UPDATE: 40m Solar Noon DX Challange

[Jerry Wothe]

Bill:
A fast and easy way  to conduct your research on the propagation any time any band is by pointing your antenna, if you have a point-able antenna, anywhere and calling CQ on CW and after a few CQs go to the reverse beacon web site and see who heard you. There are receivers on that network all over the world and from that will give you a very good map of the propagation. Using that system you do not have to depend on a station being on some place you may or may not hear depending on if he has a big enough signal for you to hear. 
Here is the Reverse Beacon website. http://www.reversebeacon.net/srch.php
