Many Mathematical models have been proposed to predict the quality of radio links or station coverage maps or coverage radii. One well-respected model for predicting VHF\/UHF\/Microwave communications is the ITS-Irregular Terrain Model, or Longley-Rice Model. <\/p>\n\n\n\n
Roger Coud’e (VE2DBE) has developed a software package called Radio Mobile that uses this model in a user friendly way. It connects with on-line Terrain, Land Cover and map databases and allows easy entry of your station parameters (location, radio and antenna specs). It can predict pretty accurately, performance of a link between sites or map your station’s coverage to mobile or hand held users based on statistical success criteria you can set.<\/p>\n\n\n\n
I plan to share my screen while I go through the process of entering the required parameters into Radio Mobile and we investigate some point-to-point paths between members’ QTH’s and other members and\/or repeaters. We will also generate coverage maps that take into account available terrain elevation data that is relatively fine-grained (on 30 foot spacing grids). I hope it will be fun and introduce you to a very useful tool that some may not have known about before.<\/p>\n\n\n\n
