I recently purchased a used uniden homepatrol-2 scanner off of ebay for $289.99. It was described as being in very good condition. The scanner looked fine, but the reception is horrible. The scanner will scan, but cuts out after a few seconds of radio action. I only live 20 minutes away from town. I have taken it into town, and the scanner is no better. Sometimes, it picks up nothing. Is this because it is used? would a new one preform any better? I have also noticed it will not charge and only works when plugged in. My main question is this: Is the scanner a dud, and should I return it and get a new one? would a new one vs a used one preform any better?
