11th August 2PM: High frequency (0.1-2.5 GHz) sniffing and spectral
analysis with ap/xxxxx.

A practical examination of wide band, high frequency RF/EM emissions
in a small part of Berlin. Participants will construct a sensitive
high frequency sniffing device based around the tiny Analog Devices's
AD8313 logarithmic detector chip which provides an audio signal
output for recording, ambient use (en route) or spectrum analysis.

Participants will construct a simple, surface mount component-based
board which can then be used as a portable sniffer. We will also
examine further amplification and antenna designs: the famous cantenna
perhaps, or humble dipole. Finally, Baudline software will be used to
analyse local signal spectrum.

Requirements: All tools provided, a Baudline equipped laptop would be
helpful

and embedded code, environmental code, noise, transmission and
reception, and electromysticism. Workshops solely utilise free
software and GNU toolbase.

Practitioners include Julian Oliver (http://selectparks.net/), Derek
