hey jim, I went to Los Angeles this weekend and noticed a huge difference in reception and sound quality. In san diego it usually cuts out under every bridge and even when at a drive up atm or drive through window. In LA it never cut out under bridges, i even got reception in a parking garage! The sound quality improved too. I think there are spots that the satellites are aimed at and everyone else in surrounding areas only gets what they can pick up.Super Doody said:
