[Hallicrafters] OT Atomic Watch

[Duane Fischer, W8DBF]

Hi All,

Question: What powers the so called "Atomic Watch"? Is it solar powered? Or?

Supposedly it calibrates itself when placed in a window overnight once a 
week. Is it using a WWV signal or is it using some GPS signal?

Nobody seems sure exactly what powers these things! Does anyone know for 
sure?

Thanks.

Duane, W8DBF
