As a ham we've all at some point heard and used WWV and WWVH for setting our clocks, guessing propagation, and getting solar info. There are even non-hams that use WWV without realizing it. They may have a self-setting clock that will listed for the time signal at least once a day and set their clock. And chances are your computer goes out to the NIST website and auto-set's your clock (if you're on XP and above, or OS X).
Right now they're conducting a survey online that might be beneficial to all of us hams out there.
Help make WWV and WWVH a little better by filling out the survey today!
