I have entered all the sites and the radii in which I want to listen to them. I used MapSource because it is the map program used with my Garmin GPS's (is plural gpii ?). If you happen to have Mapsource I can send the file, then you could change the radii, show only sites of interest to you, and add new sites. Otherwise I can do a screen print and send the image.Is there a site map out there that shows where the sites are located and their coverage with out clicking on each one individually?
