Hummm.

Its not a bad soution. Only problem is that I don't know if it would work with the US system.

Yep, I mean 60khz:P

Still it is kind of prebuilt though. And I don't know if the huge rise in atomic clocks use a ferite core tuner. From what I have read you don't need that kind of accurcy to read the signal.

My casio wrist watch reads the atomic clock signal, if it can do it while underneath bed sheets and in a bedroom filled with lots of electronic noise, then something tells me you can build it with very minumual parts.
