From FB comment to Bill Sherman’s atomic clock’s damaged LCD
At our computer club one of our members talked about this. Over 3 years ago NIST added phase modulation to WWVB. Only one of the makers of ‘atomic clocks’ has just come out with a clock that demodulates this phase modulation. LaCrosse has a wall clock, and he showed us the one he bought. It’s a hundred times more sensitive than the older clocks, so it will receive the signal even when the clock is on an inside wall. His house has the attic insulation with a layer of aluminum foil, and his other clocks won’t pick up the signal unless they are on an exterior wall. But this new clock works anywhere.
