[Brent Gordon]

You're welcome Greg.  I'm glad I could post something useful to this list.

I was exploring the WWVB website last night and discovered the page that 
lets you see WWVB reception in different parts of the country.  For 
anyone interested, here's the gateway page that lets you see reception 
in Boulder, Gaithersburg, LaCrosse, and Santa Clara:
