Signal & Systems
Systems built in the field and in the business. Project documentation by William A. Atkins, KR4JSQ.
I build scalable systems that help organizations grow. This site documents the systems I build outside the boardroom too: field software, vehicle upfits, radio and emergency communications, and the business frameworks behind growth and revenue operations. Every project is written up in enough detail that you can learn from it or reuse it.
