I use that station to calibrate all my electronic signal generators. I use a commercial synthesized receiver going from 10kHz to 30Mhz for that to heterodyne and listen/look for zero beat frequency re WWV and let's say the time bases of my generators. Once there is zero beat the oscillators are dead on. No household has a cesium frequency standard - way too expensive. It is a nice 19" rack mount box though! Hewlett Packard builds them among others.<br><b>References : </b><br> That would be WWV in Boulder, Colorado operating on 5, 10 and 20Mhz.

There is a radio station in Colorado that broadcasts a standard time signal that can be picked up in most of the US. The clock receives that radio signal and synchronizes to it. Can't get it in New England, however. .<br><b>References : </b><br> Nothing to do with a PC.
