Office of Spectrum Management (OSM) is responsible for managing the Federal Government's use of the radio frequency spectrum." There are many informative features on the OSM Web site, most notably a collection of studies and reports about federal policies and regulations. Included in these reports is a long-range plan for accommodating the growing spectrum requirements of the government. Another interesting document is a detailed chart of frequency allocation in the US, which shows the range of frequencies reserved for specific radio services. The site is updated often with national and international news and hot topics.
