Anybody using "Viewshed" in Google Earth to determine repeater coverage??

Is anyone using the "Viewshed" tool in Google Earth to graphically show a repeater's coverage map?   I know the tool is limited to a 6-ish mile radius - but IF something like this tool was available on the GMRS map - it would be fantastic!

To use the tool on Google Earth, you first pin or "Placemark" the repeater location - then right-click for the Viewshed tool (you can also adjust the placemark above ground).  This shows the Line-Of-Sight all around that location...

It works great - but the Viewshed radius is too limited for my uses.

I have used it to optomize repeater tower placement for a project that required local in building coverage and there were tall pine trees throughout. It helped me in placing the tower where it could best serve.

A commercial product, Comstudy, has been doing this for more than 20 years. At one popint, all the Part 90.20 coordinators used the software until they invested the resources to develop their own products.
