... Well, it would be if it worked. The clock synchronizes with WWVB every night, and I had it working on my engineering bench. But with it mounted on my air studio wall, it won't sync. I've tried three different positions -- mounted flat on west, north and east walls. In each position, I left it there for about a week to see if it would sync. I'm in Atlanta, so WWVB is generally west from me. I don't know how the internal antenna element is oriented, but I assume it's parallel to the big flat dimension of the clock, so either east or west should have worked best. Obviously the building is attenuating the signal, but I really want it to work in that room, so I've got to find a way to improve the signal reception without moving the clock much from where it's at. There are some hints at the NIST website. I live in Florida and the nighttime signal is much better than the daytime signal. This is also true for Atlanta, but not as much variation as at my location. One thing that helps (sometimes) is to move the clock away from TV receivers and monitors. A 60 kHz antenna is a large beast, so there is nothing simple that you can do in that department. I have two of those "atomic" clocks, one at home and one at work. Both came with admonitions in the instruction sheet to keep them at least 10 feet away from any computers, monitors or TV sets. Naturally, all of these items generate intense EMI fields around them and would swamp the weak 60KHz signal from WWVB. Unless you can satisfy these criteria, or provide an external antenna that you could couple to the internal antenna of your "atomic" clock, then I'm afraid you've a couple of boat anchors on your hands. Your clocks can only syncronize if they have a signal that is strong enough to allow it to receive the coded information that it needs to set the clock. Antenna placement is critical for these clocks. -- Tweetldee Tweetldee at att dot net (Just subsitute the appropriate characters in the address) Time is what keeps everything from happening all at once. |
