Wwvb Signal Map

Wwvb Signal Map. Simulated coverage area for the legacy WWVB broadcast at 0800 UTC Red indicates areas where signal levels are 100 microvolts per meter or greater Signal strength varies throughout the day, depends if you're inside/outside, surroundings, interference, etc

Signal strength varies throughout the day, depends if you're inside/outside, surroundings, interference, etc The top graph shows the measured field strength of WWVB at the monitoring site

PIC based WWVB clock

Computer-generated estimates of WWVB signal strength under typical conditions show coverage at two-hour intervals over the course of a day with WWVB operating at 50 kW radiated power The WWVB signal is continuously decoded at each of these sites to determine the current signal conditions for radio controlled clocks (RCCs) The WWVB time code is sent at the very slow rate of 1 bit per second

WWVB The source of the Atomic Signal in North America WatchCrunch. Red indicates areas where signal levels are 100 microvolts per meter or greater The shaded areas indicate those areas where signal levels are 100 microvolts per meter or greater.

WWVB DX Virgin No More. [1] Most radio-controlled clocks in North America [2] use WWVB's transmissions to set the correct time. In fact, some receivers have much better sensitivity (20 or 30 microvolts per meter)
