Watch out for the 440 Hz tones near the top of the hour. You also need a
clock<g>. The schedule is published.
(
http://tf.nist.gov/stations/iform.html). Some minutes have NO tones.
Patience is required.

I connect the computer running Spectrogram and listen to the transmitted
tones - WWV transmits 500 and 600 Hz tones on alternate minutes, and I look
for these tones displayed on the Spectrogram screen - I set markers at 500
Hz and 600 Hz - then adjust the tuning until the tones line up with the
markers. It is easy to get within 10 Hz this way.
