Crisp on the outside, thoughtful on the inside. A keeper.
Summary
This article explores the historical context of radio frequency interference (RFI) and how the FCC's crackdown on computer emissions in the 1970s-80s was largely driven by the CB radio craze. It traces how amateur radio operators and CB enthusiasts created widespread interference problems that led to strict FCC regulations, which then created significant challenges for early PC manufacturers who had to comply with new electromagnetic emission standards. The piece connects the dots between popular radio culture and the regulatory environment that shaped early computing hardware.
