La Crosse Technology WT-3102B 10-Inch Atomic Analog Clock

I own 8 atomic clocks 5 of which are these LaCrosse brand clocks. Unfortunately, the only problems I've experienced are with the LaCrosse. The others have been problem free. Although I am very close to the Colorado transmitting station (Utah), some of my LaCrosse clocks have had a hard time picking up the atomic signal. I'd wake up in the morning or come home from work in the evening and notice several clocks were WAY off the correct time. (Sigh) I've had to reposition the clocks several times and ended up locating them in areas I really didn't want them. But I finally got all of the LaCrosse clocks to work at least.

Some of the LaCrosse clocks tick loud enough to disrupt sleeping. Others don't which is odd because they are all the SAME model. I've had to rotate clocks around until I found one quiet enough to put in my bedroom. But the quiet one has a signal receiving problem, so I had to put it on a different wall and move the artwork to a different place. It looks...Read more

I purchased this clock which is advertised as Model # WT-3102B. The clock that I received is Model # WT-3102. I do not know what the difference is between the two model numbers but my clock does not work properly with the new daylight saving time rules. I tried to call LaCrosse technical support and the line has been busy for several days. When I finally got through the most you can do is leave a message in voice mail for them to call you back and they have not called me back. Although LaCrosse advetises that all of their clocks are compatible with the new daylight saving time rules, this clock is not. Based on this and the lack of technical support I cannot recommend this clock.

I bought 4 of these recently, and found that while they picked up the timing signal perfectly from WWVB in Ft. Collins, CO, they did NOT 'spring forward' for DST. Since the DST indicator bit is part of the time-code signal, this was very confusing. I just got off the phone with LaCrosse technical support, and they acknowledged that this is a known-issue (just confirmed in the last couple days), and the WWVB receiver IC used in any of the movements with a red sticker on the back IGNORES the DST bit sent on WWVB (and uses the pre-2007 DST date algorithm instead.) LaCrosse is taking names and numbers and will supposedly be contacting everyone in late April with instruction on how to exchange the product for a working one.
