Well Dunno but I have 2 of the big ones digital also displays
indoor and outdoor temp. They are fed by wwvh just one island away from me on Kauai. I have no problem it stays locked right to the second. Once in a while the Kauai WWVH goes down on both 5 and 10 mhz for hours if not days. Then the 2 clocks loose it of course. WWV on the mainland is almost inaudible out here most of the time except if conditions are good the 15mhz sig comes thru fairly well and the clocks sync on it.
