Switching to Broadcast Cable -- will I lose the PBS "sub-channels"?

You can check with them, but from what I have seen, switching down from basic cable will cause you to lose most of the sub-channels on each broadcast channel. I switched down from basic, and now have PBS 2, converted to og and 2.1 (digital only.) However, I do get 7, 7.1, and 7.2...If you are not in the 'boonies'..you might consider an AMPLIFIED digital antenna, which will give you all the local channels and all the sub-channels..(As long as you are not too far from the broadcast towers.)
