The part I'm a little unclear on is, in my case, I also have to move
my antenna to scan a second market.  I watch almost entirely NY
channels but also get Philly stations.  There are no frequency
conflicts between the two.  I believe that all I did when I originally
setup was to just do a second full scan facing towards Philly, just
making sure that the existing channel treatment isn't set to do
