Have you ever wanted to generate coverage plots of your local VHF/UHF station or a local repeater?  There is a  program called Radio Mobile which is a free download.  Until recently, it has been difficult to set up.  Now, G3TVU has made a self-extracting executable that will set up neary everything for you including an example.  Give it a try.  Fun stuff.  http://www.g3tvu.co.uk/Radio_Mobile.htm
