i recently signed up with voom. didn't bother to check all the channels before the installer left and found out that i am not receiving pbs (sd and hd). is there a way that i could fix this using any options on the voom set up? called up voom and was told that pbs might not have a strong signal where i'm at. i checked antennaweb.org and based on their street level map i am 11 miles from where the transmission is coming from. hope someone could help me out. thanks.
