I'll check the battery first , didn't think of that, thanks!... unfortunately everything is packed up for my move down south... That will be one of the first things I attack once I arrive at the new QTH. I love that receiver!... needs a decent AM filter installed. not a hard radio to fix but I know a good source of parts and help. Check the battery. gewingerd@netzero.net tell him I sent you.
