Here is a link to the main "project" topic that I will update if I EVER get some time:
That info is for Echostar17 Gen4 gateways.
I will have to dig to get more info in Spaceway3 gateways ... rumor is "about" the same but with a few additional.
I'm really weak on 9000 stuff as I skipped that system .. going straight from a DW6000/HN7000s to a HT1100.
Still, save the link to the above because that will be the point of update and that topic gets buried fast due to lack of interest to the average user (until things stop working of course).
I think a "corporate" person needs to be so careful as to what they say .. they are so used to the "product" that something they take for granted very well could be "inside info".
Where as the mumblings of an old twice retired duffer such as myself can be overlooked/ignored as the "musings" of ... an "Old Duffer".
