Yeah, I kinda did that years ago. The X simply means that the channel should be present with a OTA antenna. I added the "S" later to indicate channels that are also available via Satellite. I guess its a mess now and should be cleaned up. I"m hoping to rebuild those grids using the "table" feature of the site one day. I tried it a few weeks ago with the other part of the grid and had mixed results.
