I am wandering, if anybody seen the projects like WWVB simulation 
(transmitter) using GPS/NTP/whatever as a time reference ?
I have something similar, which is generic PIC MCU with connected WWVB 
antenna. This box generate WWVB signal for very short range. However its 
handy for developing/troubleshooting the WWVB receivers. There is no 
fancy parts on that - just an WWVB antenna, which many "travel radio 
clock" has under the hood. Unfortunately those box using internal 
oscillator and every time it needs the time to be setup on it.
The reason to have "GPS-2-WWVB" could be use it to sync. some watches 
without relay on WWVB signal propagation. Sometimes its a challenge to 
get WWVB in big cities because of location and QRM.
