IMPORTANT NOTICE FOR WWVB RADIO STATION USERS
Radio Station WWVB will be conducting a test of a new broadcast format from Monday, March 5th, 2012 at 5 p.m. MST through Saturday, March 10th at noon MST.

During the test, Station WWVB will be broadcasting amplitude modulation and phase modulation simultaneously.

This test may affect WWVB timing equipment, but consumer radio-controlled clocks should work fine during this test.

You are encouraged to direct your questions to the Broadcast Manager John Lowe: 303-497-5453 or [email protected]

NIST radio station, WWVB, is located on the same site as WWV near Fort Collins, Colorado. WWVB broadcasts are used by consumer electronic products like wall clocks, clock radios, and wristwatches which sync to its unique time code broadcast stream. WWVB is also used for high level applications such as network time synchronization and frequency calibrations.

Though the tests are being conducted over 5 days, timing may be less than desirable considering the pending solar flare.
