That’s an equation that just about everyone in the electronics world strives to achieve: optimum power transfer! Power in equals power out.<\/p>\n

High SWR? We don’t need no steenking high SWR!<\/p><\/div>\n

After two Saturdays of troubleshooting this issue (I’m an essential worker nowadays) this old hound thinks it’s safe to say we have a problem up top. Because of recent heavy rain it could just be water in the balun or coax, as was the case with the 80 m dipole coax that I fixed last week.<\/p>\n

For now our mighty, mighty beam has been disconnected and replaced by a multi-band Alpha Delta wire antenna, generously donated by WW5XX a while ago. (thanks James, you’re a visionary!).<\/p>\n
