Hello, I got an R7 from a SK's estate, and have verified the measurements and re-erected it. It works on most bands, except it has an extremely high SWR on 30 and 40 meters (according to my ICOM). Yesterday it poured with rain, and I tried it both during and for a time after the rain had stopped, and the SWR was in a workable range (2.0-3.0!!). Today, it is back to very high SWR (in the red, according to my Icom 7300). Would this be due to a leaky trap ? Why would the rain "fix" it ? When I assembled it, I could not see anything wrong with the traps. Ideas?
