There's software under leapsecond.com/tools that you'll find
helpful in this effort (wwvb* tco*). Have a look at:
I also have a version that uses a standard 44.1 kHz sound card
to generate audio at 60kHz/N (for example 60000/11 = 5454 Hz)
and then plays the sound through headphones next to a WWVB
clock. The Nth harmonic of the magnetic coupling between the
headphones and the clock does the trick. It works (but I found
the high pitched sound obnoxious).
