Recommended Practices for Manufacturers and Consumers of WWVB Radio Controlled Clocks



Michael A. Lombardi, Andrew N. Novick, John P. Lowe, Matthew J. Deutch, Gerald Nelson, Douglas D. Sutton, William C. Yates, D. W. Hanson


This document serves as a recommended practice guide intended to benefit WWVB radio controlled clock (RCC) manufacturers and consumers. It recommends key features to manufacturers that their products should include, and key specifications that their products should meet. It is hoped that compliance with these recommended practices will lead to the development of more reliable and usable clocks, increasing consumer confidence in WWVB RCCs, and at the same time increasing the size of the commercial RCC marketplace in the United States. It is also hoped that this guide will be useful to consumers of WWVB RCCs, by providing information that helps them select RCC products and troubleshoot RCC reception problems.
