August 29, 2005. Hurricane Katrina slammed the Gulf Coast, the levees failed, and the water swallowed entire neighborhoods. Phones went dead. Power grids collapsed. Families were cut off and 911 calls were rerouted anywhere a signal could land.

In the middle of that chaos were volunteers — amateur radio operators who carried their share of the load when the systems failed.

One of them was Carl, KB5WMY (Silent Key). In 2015, he sat down with me to share his story of working at the Bossier Parish 911 center after Katrina. Carl spoke openly about the calls he could help, the ones he couldn’t, and the weight of serving in those days.

Now, on the 20th anniversary of Katrina, we honor Carl’s memory and service by replaying that full conversation. It’s a behind-the-scenes look at how ordinary people with radios made a difference when everything else went silent. vist www.prepcomms.com for more including the bonus audio material
