HRWB 237 - Remote Operating The K4 With Eric From Elecraft

In this episode we meet Roger Coude, VE2DBE, the author of Radio Mobile.  This amazing software package allows the user to create a cross sectional plot of a radio path between two points on Earth.  The software includes a terrain database so the path includes obstructions and the curvature of the Earth.  This software can be used to determine link paths, repeater coverage, simplex point to point link budgets and more. Roger has developed this software many years and makes it freely available to ham radio operators.  A truly generous gift to the ham radio community.
