I spent a 26 year software engineering career in real-time software engineering mostly on true real-time operating systems like QNX. I am an Extra Class Radio Amateur. My call sign is K4RHB. I recently started a non-profit corporation named K4RHB Software (). to write custom applications for Amateur Radio and give them away for free. I am learning Visual Studio 2019 and C# on Windows 10.
