I'm sure a major reason W8JI leaves everything connected is because it would take him about 4 hours to disconnect it all!  :^) Jim, you have chosen to take the risk of leaving everything connected. Good for you; it shows your confidence in your own engineering. But surely you'll agree that it

As a broadcaster in South Florida with tall towers, 50' masts on mobile units and satellite uplinks, we encountered lightning strikes many times a day during the rainy seasons. Our experience is that all equipment can be damaged by the high voltage and/or current, no matter how much protection you

Peter, Mike, I think Elecraft does a reasonable job at protecting equipment inputs. For lightning protection, there is much literature on methods and practices. A principle to keep in mind is protect at the “point of entry”, the desk setup, the entry to the house/shack, etc. Another is

Lightning is like wildfires which burn some houses or land but not others.  There is no rhyme or reason why some devices are not damaged and other are.  I suspect that most items were damaged but not made inoperable. Couldn't the argument be made that the computer or USB hub should do more
