Dont know if im posting in the right location, sorry in advanced if im not but i just got my HD radio adapter for my D3 and i dont know why the HD2 stations come in and out. for instance if im listening to a regular radio station, it will say HD1 but then i can go over to their HD section of that staion and when i hear the music, it plays, then stops and just keeps going in and out. is this a reception issue or just the HD itself.
