What Closing a Government Radio Station Would Mean for Your Clocks (opens in new tab)

I have a digital clock that I received from my mom just before she passed. It uses WWV for time/date sync. It has never drifted off time. If they shut down those stations, I will have to create my own NTP to shortwave low powered SDR unlicensed transmitter.

Does anyone already happen to have any code that will use system time to generate the audio signals and time code that would replicate WWV?

Edit: I think I found two [1] [2]

How can we access the risks of turning off WWV? I know it use to be tied into all sorts of long running industrial, transportation and remote location applications. And was considered the ultimate fall back because it was so simple. Many of these uses may be even forgotten.

I remember helping to set up a LAN in the late 1980’s. They had a WWV receiver with a serial interface to set network’s time. I thought that was super cool. Not too many years before micro computers need to have their clocks set manually with every reboot.
