jimbert The part number on the box that mine came says FJ3538, so probably manufactured by Fanju. It is advertised here as having an atomic clock, but the manual does not mention it and after being on for a couple days, it is still 40 seconds off. My other atomic clocks update successfully, so I know that the WWV radio signals reach my location. I agree that the temperature and humidity are not very accurate. They both appear to be about 5 deg F and 5% high, respectively, compared to my other sources which I think are correct. It is possible to calibrate the barometric pressure if relative mode is selected. Too bad the temperature and humidity can't be calibrated. It needs to be hacked by someone to make that possible.
