This page contains a list of publications (available in PDF format) containing information about NIST radio stations WWV and WWVH. Since WWV has been on the air since 1923, a large body of literature exists. Although some of these publications contain information that is now obsolete, all contain some unique information that is not available elsewhere, and are made available here as reference material. General reference publications are listed first. The remaining publications are listed in reverse chronological order.

Since 1976, four guides have been published as Special Publication 432. From 1960 until 1974, eleven guides were published as NBS Special Publication (or Misc. Publication) 236. Prior to 1960, NBS issued the guides as "Letter Circulars". A collection of these guides has been made available here as a historical reference. |
