Hello Operators Todays discussion, operating a portable ham radio station off grid, during winter field day 2021. Like many other ham radio operators, I operated an off grid portable ham radio station for the Winter Field Day 2021 event. Winter Field Day is a a great way to gain valuable deployment experience, in less than optimal conditions. I set up a winter camp, operating on batteries and solar power, in below freezing temperatures. I hope you enjoy my WFD2021, After Action Report. 73 Julian oh8stn
