Excellent VHF/UHF Tropo Ducting Website.

Here is the link for William Hepburn's Worldwide Tropospheric Ducting Forcasts.

In the upper left hand corner where it says "SELECT REGION", just click the drop-down menu and click on it to select the region of the world that you might be in.

It's very easy to understand and very helpful if you are a ham radio operator...or even if you're not!

Here's the link:
