Here in NB, I noted the new DoD MARS announcement over WWV/WWVH yesterday (20 April) evening at 22:10 UTC from WWV on 10 MHz. The current announcement is for the upcoming Wisconsin Army National Guard exercise SIMCOM Vital Connect Wisconsin 2019 (SIMCOM-VC 2019). This specific Web page has been set up for reception reports (and a survey of WWV/WWVH use):
The main page, www.dodmars.org, is announced during the broadcast.
Some information on the DoD MARS broadcasts is now on the WWV/WWVH Web page:
