I cannot get philly to scan anything at all after downloading from radioreference using ARCXT. I have never had a problem before, I usually tune into montgomery county and Philadelphia County. When I look on ARCXT it shows all of the frequencys in there for philly but my scanner is silent when trying to tune into philly. I wish I could give more detail but I have no idea why it would not scan. I live in montgomery county but had everything loaded for philly when I was in town and nothing came over the scanner. I have tried re-loading but that did not work. Has there been any recent changes to the Philadelphia frequencys that may have caused my scanner to work correctly? Thanks in advance for any help.
