A Radio Frequency Interference survey covering 10 MHz – 18 GHz was conducted at Chajnantor, Chile,
the site of the ALMA project, on 2002 December 6 – 9. The survey provides a “snapshot” view of
existing RF activity in the area. The detected signals fell into these categories: noise from nearby
electronic equipment, broadcast TV and FM radio, and terrestrial and satellite radio services.
