I know that I can get HD locals with an off-air antenna combined with the directv HD receiver. Can I also get local digital weather stations through the HD receiver? I know a couple of them are broadcast in SD digitally. For example, if 6.1 is the local HD ABC, can I get 6.2 which is the SD weather station. I can get several of the local stations in HD via directv but I really want to have the local weather stations.
