I live in the Washington DC metro area, and even here there are signal problems even in the inner suburbs like Suitland. On Pennsylvania Ave, near Penn-Mar, the signal blanks out. On 301, going from the Brandywine Costco to Upper Marlboro, it blanked out for several miles. It also tends to be weak in the Bowie area. Lots of times, you can't change channels. Going to Gettysburg, it went dead for 15 minutes. It's not my antenna or radio. XM's signal is weak and seems to be getting worse. If it's this bad where their headquarters is, how bad is it elsewhere?
