WWV/H Scientific Modulation
Welcome to the WWV/H Scientific Modulation Working Group page!
For more information about scientific modulation on WWV, email firstname.lastname@example.org.
HamSCI's WWV/H Scientific Modulation Working Group is exploring possibilities for additions to WWV and WWVH's modulation that can be used for science purposes. For updates on this project, join the Google Group here: https://groups.google.com/g/wwv-h_scie
Thanks KE0KA for this fantastic presentation of our characterization signal:
The Test Signal
Aidan KB3UMD has ported the signal generation code to Python (note that the pseudorandom sequences are not the same): https://github.com/aidanmontare-edu/wwv-h-characterization-signal-ports
TAPR DCC Presentation, 18 September 2021:
WW0WWV has written an excellent report on the TAPR presentation, which you can read here: WWV/WWVH Scientific Modulation Working Group | WWVARC
1 November 2021: An announcement about the characterization signal has been added to WWV and WWVH! The signal is scheduled to begin at Minute 8 on WWV and Minute 48 on WWVH, starting on November 15.

If you would like to make recordings using your SDR: We recommend making I/Q recordings, centered on a WWV frequency (2.5, 5, 10, 15, 20 MHz), with a sampling rate above 20 kS/sec.
If you have a KiwiSDR that you are willing to let us use for remote recording, please email email@example.com.
