The Women's March on Washington was a (pardon the expression) HUGE event the day after President Trump's inauguration. While it was politically charged, it was also an event that needed communications assistance to keep participants safe. The cell phone system worked, but it was so overloaded that even the usually reliable text messaging slowed to a crawl.
Our guests Arthur Feller W4ART and Christine Axsmith KC3CIF put together an ad-hoc group of about 30 hams, drawn partly from the group that provides communications for the Marine Corps Marathon each year. They tell us their fascinating story, including many real-world lessons for hams participating in any large-scale event.
