"NIST has developed, tested and is now beginning to implement the new phase-modulation WWVB signal... "This change significantly improves signal reception and overall performance of new products that are designed to utilize this new protocol. Legacy clocks and watches will still continue to function as they have because the amplitude modulation remains the same, but they will not benefit from the increased performance of the new phase modulation protocol, Lowe said. "These new products and non-networked systems will be able to take advantage of the improved NIST broadcast format thanks to next generation receiver chips that will begin entering the marketplace in 2013."
