I've been a member for awhile but silently for sure. I'm trying to understand the whole satellite communications chains and then want to drill down from there. Is this forum appropriate to do so or is there a better place to go? Is there any written materials to know things like: How many sat's are above us to serve the western region of the USA? How many channels can one satellite handle? etc. etc. I'm sure as the answers are revealed it will generate many more. I'm a DISH Network customer and want to understand more.
