re: #78 Sherlock Hound

The receiver works once a day at local midnight, and receives at a very low frequency. You may have trouble if it’s not near a window. I had one, and it received when it felt like it—I have a bad location for any radio signal.

That’s because WWVL transmits at 60 khz, which a lot of watches and clocks use as their time source. Cellphone towers (and some hideously expensive watches) have GPS receivers and use those as their time syncs. PC’s use NTP servers.
