Radvis ("Radiation Visualizer") is a simple simulation suite for designing and visualizing antenna radiation patterns in 3D. It also provides an feedback on the given antenna's efficiency estimate, including SWR plots across any given band. The application is also equipped with a small set of pre-defined antennas for testing, allows multiple elements (both active and …
For a long time I've been addicted to Pileup Runner, the CW pileup simulator application for Windows. Since I didn't want to install it everywhere I go (and being a Linux guy) I decided to create my own version of it which runs entirely in the web browser. The behaviour should be close to identical …
Propagation Simulator is an educational propagation-simulator running entirely in the web browser, without the need of any back-end software. It features interactive 3D modeling to help aspiring operators visualize and comprehend how signals bounce through the ionosphere. By adjusting power, frequency bands, and time, users get an intuitive, visual look at atmospheric radio wave behavior …
