I plugged in the unit and the radio is unusable. In AM mode it buzzes so loud, I can't hear a single station. FM buzzes less loud but still unusable. I tried it at a friend's house and it had the same loud buzz. I called Scott's 800 number and they said they are aware of the problem with their remaining stock and to NOT SEND IT IN to them since they would just send me another buzzing unit.ps - the unit does change automatically for daylight savings time apparently, but will now do so on the wrong dates since it is hardwired with the old change dates from years ago!!
