Welcome to DesertHail.com! Over the years I've written a lot of software, usually to fulfil a specific personal need. I created this page to share a little bit of it with the world. Everything here is available to download, use, and re-distribute freely for any purpose. It is my hope that you find something useful. Cheers!

RadioWORKS
RadioWORKS is a tool for calculating various items related to radio waves and radio wave propagation. Get detailed information about a frequency, such as the free-space wavelength, band classification, propagation methods, common transmitter configurations, etc. Calculate antenna lengths or frequencies. View a 3D coverage map by providing a latitude / longitude coordinate and transmitter height. View a 2D representation of line of sight coverage between two latitude / longitude points, including compensation for TX/RX height, adjustment for Earth curvature, and first Fresnel zone calculation. Look up the elevation of a latitude / longitude coordinate. Calculate path loss using the Free-Space, ITU Terrain, Hata Urban, Hata Suburban, Hata Open Area, COST 231 Hata Extended, Weissberger, or Empirical COST-Walfisch-Ikegami (Also known as 'COST 231 Empirical') non Line-of-Sight (n-LoS) and Line-of-Sight (LoS) mathematical models -- OR -- run the models backwards to get the matching distance for a given path loss value. Use the Distance and Power change prediction calculator to predict how a proposed transmitter power change, whether an increase or a decrease, will affect your usable range -- OR -- how a proposed range requirement change, whether an increase or a decrease, will affect your transmitter power requirements, while factoring in the signal decay rate observed in your current system. All path loss & distance / power change prediction calculations can also be displayed graphically. Calculate the beamwidth, gain, and far-field distance of a dish antenna. Context-sensitive help is available to guide with the usage of the various features. Additionally, all mathematical formulas used by the application are on display, including explanations and usage information.
