Replace over-air time by Internet time About twenty years ago I recycled and modernised a vintage clock with Nixie tubes built by my father in the nineteen seventies. I replaced the digital logic by a microcontroller and used a DCF77 receiver module instead of the original 50-Hz derived timebase.

About twenty years ago I recycled and modernised a vintage clock with Nixie tubes built by my father in the nineteen seventies. I replaced the digital logic by a microcontroller and used a DCF77 receiver module instead of the original 50-Hz derived timebase. Over many years the clock has worked fine, but recently DCF77 reception in my house has worsened due to electromagnetic interference created by modern switching power supplies, I suppose. So I decided to replace the DCF77 receiver by some form of Network Time Protocol (NTP) client.
