 Previous: First Australia-US QSO took place 80 years ago |  Next: Fun is the Focus for this Pennsylvania Club |

This week, we go to the net to seek and find predictions of propagation in graphical format.
A few days ago, I received an e-mail asking if I know of any Web sites that forecast HF propagation online in a graphic format. Here is what I know:
Tomas Hood, NW7US, runs the Propagation Resource Center Web pages at HFRadio.org, which have a lot of useful propagation information presented in text, tabular, and graphic format. The site also offers an "eAlert Service" that automatically e-mails you when the solar and/or geomagnetic conditions change so you can stay informed about current conditions.
 On-Line HF Propagation Prediction Web site of Serge Stroobandt, ON4BAA, presents radio propagation data in graphical and textual formats. |
Serge Stroobandt, ON4BAA, maintains the On-Line HF Propagation Prediction Web site, which is another site that graphically represents lots of information. Be sure to check out the Grey Line link, which allows you to open a window containing an Earth globe that displays the current light and dark sides of our planet (courtesy of Chris Bruns' Globeview Java applet).
Serge's site has a link to the Propagation Primer Web page of Geoffrey Noles, AE4RV, which bills itself as "A simple HF propagation primer." This introduction to radio propagation is in Flash format, so if your Web browser does not have a Flash player, you will have to download one from the Macromedia Web Players Web page. (Although this has nothing to do with propagation, after you finish the primer, check out Geoffrey's Virtual Vibroflex Bug; it is neat!)
Finally, for text-only propagation forecasts, you can't beat the old and reliable W1AW Propagation Bulletins.
Until next week, keep on surfin'
Editor's note: Stan Horzepa, WA1LOU, can finally get some sleep because the World Series is over (and his team won). To discuss the World Champion Boston Red Sox, radio propagation, and other passions, write Stan by sending e-mail to wa1lou@arrl.net.
