[time-nuts] WWVB SDR discussion

[Mike Feher]

So far I have only put batteries into one of them Tom and I agree with you. It is ever so slightly off. However, it is so small it is barely visible on the minute hand. The second hand seems right on. To use as is, as a clock, it is more than fine for my 75 year old eyes 😊 . Nice hearing from you. It has probably been about 20 years since you got those HP journals from me and I got some nixies from you. I am no longer concerned about picoseconds as days and years go by way too fast. Stay Healthy - Regards - Mike

Mike,

I've used that seller a lot; no worries. They have 800+ items for sale, mostly clock and weather products by La Crosse Technology [1]. It looks like this eBay seller is their online retail store, as well as an outlet for their overstock and refurbished items:

https://www.ebay.com/itm/274056463528
Seller: greatbigoutlet
Item location: La Crosse, Wisconsin, United States
Condition: Manufacturer refurbished

One of the complaints that I had about the La Crosse 404-1235UA-SS UltrAtomic clock was that several of the ones I bought had misaligned hands [2]. If you're into Lavet stepper motor watch movements using optical feedback it's something you can fix yourself. The other solution is to return it to the factory. It wouldn't surprise me that La Crosse has a pile of these refurbished clocks for sale. Or maybe 1235UA just never sold well; or maybe there's a new model coming; who knows.

And, yes, this is a deal for $35. They are so much better than older WWVB clocks. AFAIK it is still the only LF radio clock that uses the new eWWVB PM format. The smaller clocks and watches all use the legacy WWVB AM format.
