May be a moot point if you're just doing this for the heckuvit but
there's nothing to listen to per se at WWVB since the time is encoded
with pulse width modulation, ie no voice.

I'm hoping that what I build will at least give me some idea of
the WWVB signal strength. I started out being curious about the
various "Atomic clocks" and thought about building a dedicated
60kHz WWVB receiver, but one of the problems one runs into with
an idea like that is that "debugging" can be exremely frustrating
without some piece of equipment that can offer a "second opinion".


For $14 you can buy a decent converter- and put it on a decent receiver.

WWVB may be strong, but you may never know with your idea, - not knowing
your converted receiver's sensitivity, immunity to overload, images and the
ability to have a decent antenna.
