This was part of a project to apply for funding for a network. I had the Latitude and Longitude and elevation for each of the radio towers and made propagation maps in Radio Mobile (running on VirtualBox). The maps then went through Photoshop and were plopped into an Illustrator map. General coverage areas overlay the exact coverage areas so when the whole thing is printed out as a poster the client can view the network in general or detail.
