Short Description UTC (Coordinated Universal Time) time standard transmission from NIST (National Institute of Standards and Technology) stations WWV in Fort Collins, Colorado USA and WWVH in Kauai, Hawaii.
I/Q Raw Recording
Audio Sample
UTC (Coordinated Universal Time) time standard transmission from NIST (National Institute of Standards and Technology) stations WWV in Fort Collins, Colorado USA and WWVH in Kauai, Hawaii. Transmission consists of voice and time coded reference markers. Used for time reference. Also used by NOAA to broadcast marine storm warnings and geophysical alerts at 18 minutes (WWV) and 45 minutes (WWVH) after the hour. Please note that the 25 Mhz transmission is experimental.

Antennas[edit]

There are five antennas total, one for each frequency. Each antenna is a half-wave vertical to radiate in an omni-directional pattern.
