I have a 301 that is currently using a dishpro lnb. I think the lnb is bad, as I all of a sudden can't get anything off of 110. I have an old legacy setup that I was going to try, with the SW21s to go with it. I remeber reading something long ago about having to clear the 301 to do this and avoid burnig the legacy lnbs because of voltage or something. I searched the forum to find how to do this, but couldn't find it. Any help would be appreciated. Thanks from a long time lurker.
