I am a satellite communication engineer, specialising in spectrum and regulatory engineering, interference analysis and frequency coordination. I have been programming since the mid-1970s (I used to be able to code by hand-punching Hollerith Cards!) but for the past 20-years or so I have really not done much coding at all. I'm trying to remedy that by learning MATLAB!
