Spark Gaps to Spread Spectrum, Crystal Sets to Software Defined Radio


This session will present Ham Radio/Amateur Radio in a context that is relevant and interesting to our fellow hackers/geeks. An introduction to the hobby, its origin, major milestones and an overview of current areas of endeavour will be given.

A practical tour of contemporary areas such as Software Defined Radio (GNURadio), APRS and Amateur Satellites will be provided as well as more traditional operating modes like Morse Code and portable low power (QRP) HF communications.

In addition to the practical demonstrations, relevant Linux/Open Source software will feature prominently in the session as will some photos from the author's respective activities.
