	I was curious to see how much difference there is
between the time it takes the audio to go through the phone
versus how long it takes it to bounce off the ionosphere so I
called it while listening to the radio. Surprisingly, the phone
is about 1-tenth of a second behind the radio here in
North-centrral Oklahoma on Suddenlink telephone which is
voice-over-IP.

	Anybody else could have a slightly different experience
depending on one's distance from Ft. Collins and their
long-distance telephone configuration.

	I noticed that if the tone is on, one can clearly hear
the ticks every second and, while you can not directly hear the
100-HZ BCD time code, it is on the input signal WWV feeds in to
the phone line because it kind of mixes with the tone a bit.

	When the tone goes off, the ticks are mushy sounding
probably due to the VOIP codec which is excellent for voice but
not really meant for odd-ball signals like this.

	As a dedicated cheapscate, I am thrilled we have
unlimited long-distance in the United States as I wouldn't have
tried this experiment if it was an added toll call.
