Hi Frank,
I did some Googeling last night and found several articles that did
specifically mention WWVB as one of the stations being shutdown. I must
have overlooked that earlier.
I guess there will be some disappointed people (to say the least) when they
find out their expensive radio controlled clocks or wristwatches no longer
automatically synchronize.
