Numbers stations are shortwave radio broadcasts of coded messages believed to be intended for undercover agents. While the height of their activity was during some of the tensest periods of the twentieth century these stations continue to operate today, transmitting their oblique messages to persons unknown.

Shadows of the State adapts open source research and satellite image interpretation techniques in order to investigate these mysterious broadcasts and to locate the likely transmitter sites of thirty of these stations. These sites are then mapped using high resolution satellite imagery and the signals themselves are made visible to in the form of radio spectrograms alongside recordings and extensive information about each station.

Lewis will present a special Institute of Acoustics focused talk on his research on the history of number stations, triangulation methods, and spectral analysis on signals.
