Anyone that follows my ramblings know my Lets talk about series. It's master index can be found here:

Wikipedia has a marvelous article on WWV.For those whom are unaware WWV is broadcast at 10Mhz as an AM signal with lots of sidebands, and the broadcast carrier signal is derived from an atomic clock. The National Institute of Time Standards (AKA NITS) provides the service as a public service and is sponsored by the federal government There was a rumor its funding had been cut but it seems to be just a rumor. If you are wanting to know more see "Is WWV going away?". We could theoretically use the 10Mhz signal to fine tune a time base to an atomic clock. How cool is that? I will attempt to design a circuit along with a 10Mhz time base to be used in things like home brewed freq counter. Notice I am not talking about using WWV as a time base.. Being a shortwave signal, Reception is spotty pretty much anywhere you live unless you happen to live close to Ft. Collins, Colorado. in which case you could probably use it as an excellent time base as is.
BTW, the internet web site is pretty cool too.
I am going to do something a little different on this article, While I will post my ideas and show how I would do this, this thread is open to anyone to show how they would accomplish this. So lets get started!
Since I just started this thread. It will take a couple of hours/days to develop and draw my ideas.
