I didn't need a search engine to figure out what the uplink reports were. From reading a few of them, I could determine that the reports are comparisons between a list of channels, transponders and satellites that Dish currently has configured. Each time there are changes to the satellite configurations, a new report is generated detailing those changes. From deduction, I determined that there are multiple satellites at different geostationary orbits (measured in degrees West of the meridian), there are multiple transponders transmitting signals from each satellite, and there is a difference between a spotbeam (pointed at a particular city/area) and CONUS beam (covering the entire continental US).
Looking into further detail of each report, I also determined that Package Flags indicate which programming package a particular channel is offered in, Available or N/A tells whether a subscribed customer can see that channel, and Free Preview is when a channel is viewable to all subscribers regardless of which programming package they subscribe to.
If you have any more questions, let us know.
