It’s not a comedy if you’re living through it. Bad news out of Texas gives us an opportunity to look at what can happen when energy policy and weather conspire to pull the grid down. If you live in the upper Midwest USA like me, or New England, or for… Read more »

A curious trend. Just over two weeks ago, traffic to Off Grid Ham exploded. By January 15, OGH racked up more page views and unique visitors than it usually gets in an entire month. At this writing the website has surpassed its previous monthly traffic record by many thousands of… Read more »
