Yes, I concur for at least the US. A 60KHz will get us US, something in England, and Japan (decoding software needs to be different, but not the radio parts). Maybe that's good enough. > The company used to be called "Temic", not sure if they are > still called that. I've found two: http://www.mas-oy.com/archive/da9180.pdf This looks like the winning solution. Here is the TEMIC: http://www.ortodoxism.ro/datasheets/Temic/mXyzuryv.pdf This seems to not be as well supported. If anybody knows any more, please let me know. I have disassembled several WWVB watches. Of course, they are all COB (chip on board), but just from the chip dimensions, I know the chips they use (and the WWVB part seems to be separate from the watch logic otherwise) aren't either one of the above. Strange. Must be a high volume bare die house somewhere that is doing this. Our concept might well benefit from COB due to our volumes (>10,000, perhaps millions). -- Mike Ciholas (812) 476-2721 x101 CIHOLAS Enterprises (812) 476-2881 fax 255 S.
