I recently started my freshman year at Kent State University which is northeast of Akron, Ohio. I brought along my Sangean PR-D5 but the AM reception inside my dorm room is terrible. There is this white noise that smothers every frequency allowing only the strongest signals to make it through. I've heard using a longwire helps, but I'm not sure if I can do that because my radio doesn't have any antenna inputs. So far I've just gone outside, but that's not very practical for several reasons. Most obviously is that it will get cold in a few months, but there have also been several muggings on campus so I don't like to go out by myself at night. Any tips here would be great.
