Start Problem with atomic clock updating

Problem with atomic clock updating

This is mainly a problem for the wall clock in my garage workshop.

New changes to the NIST WWVB time signal, broadcast at 60 KHz., are visible on this oscilloscope.

Changes in the overall height of the wave are amplitude modulations, the method WWVB has always used to encode time information.

To understand that, you need to know about the amplitude-shift modulation scheme used to send the time signal.
