I have had local interference on a couple of my clocks before, usually after 24 hours and a nighttime period it syncs up just fine. Computer noise can be a problem on those receivers.
If they defund WWV I don’t think they realize that most of that staff still needs to be there for the atomic clock and the GPS system anyway so it wouldn’t be a huge savings other than maybe a transmitter tech or two and the electric bill reduction. I think it was probably an ill-advised suggestion for a cut until they realized how many systems rely on that signal.

No worries about that signal. I thought it was 60 KHz. In any event you can pick it up almost everywhere. You should not have to wait more than a half hour for a clock to lock on. You might have a bad clock or something in the environment making the signal a bit weaker. I was doing a solar panel tracker a few years ago and was wanting to use this signal to get RTC info. Turns out the only receiver chip manufacturer had stopped making the chip. Reason was, an antenna, capacitor and perhaps a transistor is all you need to feed the raw RF directly into a MCU chip. It is pretty strong.

But I did a couple Google searches, and was the federal government actually planning about a year ago to defund WWV and take it off the air? Seriously? And that didn’t happen, right, WWVB is still transmitting? I was a little surprised to realize there is just the one transmitter site in Colorado, and that WWVB transmits on such a low frequency (50 kHz) and sends 1 bit per second of data. _____ -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com
