Should WWVB go off the air (and it's far from certain that it will), there might be a market for a USB dongle that plugs into a PC that outputs the correct code on 60 kHz. I'm sure there is an FCC Part 15 specification that is lenient enough to prevent the transmitter doesn't run afoul of intentional radiator rules but that still allows clocks in an average house to see the signal. The problem with marketing that product is that while there are (say) 10 million WWVB clocks in US homes, there are only 27 people (not counting time-nuts subscribers and employees of NIST) who know that those clocks are disciplined by a government radio station. When they stop receiving the signal, most of those 10 million clocks will be discarded because the owners will assume that "the atoms in the atomic clock finally ran out" ("Ah never did think Mildred was too smart bringin' in that atomic clock what with the radon and all.") I'm not certain a product with a potential market of 27 people (plus time-nuts subscribers and the still-employed NIST employees) is enough to make it worthwhile. But if WWVB does go dark, I would like one of the dongles so my mantel clock will keep good time. -- Peter Laws | N5UWY | plaws plaws net | Travel by Train! _______________________________________________ time-nuts mailing list -- time-nuts@lists.febo.com To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
