Considering purchasing the HP-1 and wonder if any forum members have experience using one in Delco, PA. I'm a longtime scanner user and ham but have monitored mostly within my county for the last ten years or so. Would like to expand my listening (the easy way) to trunked and digital broadcasts and wonder how this unit performs in my area. Located 10 miles from center city Philly but since I'm told that digital system broadcasts "inward" and might be a tough catch without a roof antenna. Any input on any of this would be appreciated, tnx.
