I live in Erie, PA (16508), which D* does not carry locals in my area, but I currently receive Cleveland locals (D* thinks I live @ 44123), and wanted to know if I bought the AM21 in late Feb if I would be able to pick up the OTA SD/HD channels for the Erie DMA, even though the HR20 (which I assume acts like a AM21) does not "scan" for channels over the air. I guess my question is, does the HR20 only look for OTA locals in the DMA where your D* account thinks you live, or do you have an option of scanning or even entering the zipcode you want to receive OTA locals from?
