[Elecraft] OT: Nixie clock

[Walter Underwood]

According to the assembly manual, it uses the power line 60Hz as a frequency reference. Last I heard, the utilities actually manage the frequency so the long-term average is very close to 60Hz.

If you want real-time data on power line frequency, check out the FNET measurement network. It looks like my grid is currently at 59.990.
