Re: [time-nuts] WWVB sync
Not to beat the topic to death, I did have an occasion to repeat the WWVB signal. Although the signals here in Utah are very strong (3-5 millivolts/meter, maybe) they weren't strong enough to find their way into a noisy office building, so about a decade ago I built a system for a friend of mine that works there http://ka7oei.blogspot.com/2012/08/receiving-wwvb-indoors-so-that-your.html Apparently, its been duplicated elsewhere for DCF77, etc. It may be possible to carefully null the MSF signal without also taking WWVB out too much, but Murphy says that anywhere it's needed, MSF and WWVB will be exactly 180 degrees apart! * * * There are also some passive booster systems, such as this: http://newdwf.com/viewtopic.php?f=59t=4736 This is just a large-ish resonant ferrite antenna circuit into which one places the watch (or whatever). This passive device may not help with QRM from MSF or something local like a switching supply, but it ought to work in cases of weak signal. 73, Clint KA7OEI David McGaw, N1HAC wrote: Guys this is just silly build a 10' square loop and preamp.

Re: [time-nuts] WWVB sync
Bob wrote: Some of these clocks and watches seem to like midnight as the magic time to synchronize. That's certainly what the Casio's do. Mine (it's a Brookstone, I don't know who manufactured it) will go a few days without a successful sync, then it switches to trying every two hours until it successfully synchronizes. I think it will then use that time every day until you intervene manually or it has to do it again. It also seems to adjust the local XO when it has daily success -- after running awhile with daily sync, it has outstanding holdover performance. I'm in a low-signal area, but even here signal strength does not seem to be a problem. Local interference at 60 kHz, however, is a big problem. NIST Special Publication 960-14 (2009) gives recommended practices for WWVB-disciplined clock manufacturers and consumers.

Re: [time-nuts] LORAN C still on the air 24 hours SRS 700 looking good
There isn't anyone who can give you that. Lots of variables. Now since you are in Co maybe you live on a 1000 acre ranch so no other noise sources around you. But just suppose you lived in a typical RF nasty subdivision. Well your noise floors going to be much worse and I mean by an order or two of junk. I do indeed rcv LORAN C on occasion from Europe with a typical boat preamp and stick antenna. That is over water but about the same distance. So that said I did build a 10' square loop for WWVB and that system improved my reception greatly. Day 20uv to 80-100 Night 400-600uv.

Re: [time-nuts] WWVB sync
Interference can come from unexpected sources. For a couple of months I was cursing an on-off wide band noise that extended from VLF to about 5 MHz. I started tracing it with a transistor radio and found it was coming from a battery charger in my own woodworking shop. Now I turn off that plug strip unless I am actually charging a battery.
