Maidenhead Map
Every ham transmits from somewhere, but where exactly is that somewhere? Maidenhead can help. Instead of a series of Lat and Lon numbers, Maidenhead is a series of squares, divided into another series of squares, each time getting smaller and smaller and, consequently, more accurate. Maidenhead locators are typically named using four or six characters (the more characters, the more accurate.  Visit the link below to find your own Maidenhead coordinate down to 10 characters!

Line-of-sight Profiler

Follow this link below (or click on the image), then click on the map for your first location followed by a click on your second location. The site will then display a projected line-of-sight profile between the two points. If you want to include the height of a tower at one or both ends, click the "(XXX Ft)" numbers listed to the right of the coordinates of the site you want to change. Then enter the height above the ground level (take into account the roof and tower height) with a "+" in front of it. For example, if my roof is 14 from the ground and I have a 15 foot tower mounted on top of it, I would enter "+19" in the box and the profile will recalculate.
