The U.S. National Institute of Standards and Technology (NIST) was founded in 1901 and is now part of the U.S. Department of Commerce. NIST is one of the nation's oldest physical science laboratories. Congress established the agency to remove a major challenge to U.S. industrial competitiveness at the time—a second-rate measurement infrastructure that lagged behind the capabilities of the United Kingdom, Germany, and other economic rivals.

Since their inception, they have studied a wide variety of topics and have produced many research papers on the subjects. Many of the papers have been archived and are available online at the NIST Digital Archive.

Below is a sampling of the research papers related to radio. There are far more than the below list and this is a only a sample to get started. Click on the NIST Digital Archive link above to do your own searching.
