I mean.. This is the first time we have every approached the "technology" aspect of these systems. Now, I have spoken many times to your "bunky" David Ray.. But, this is the first time that we have spoken about this issue.. So I don't understand what you find so tiring... Unless of course, we have spoken about these issues before, and you were using a differnt "moniker"??One of the primary reasons for this is that their three satellite tundra orbit requires much more processing of the single than XM's two satellite system. Well, first of all.. It's called a Molynia orbit which is a highly elyptical orbit. Second of all.. The use of the Molynia Orbit has several cost advantages to the operator. One of that being a higher overall signal level at the higher latitudes than that of a GSO based system. This Molynia orbit can allow SIRI to operate with fewer terrestrial repeaters than that of a GSO based system. So the higher average signal level from the space segment actually decreases the amount of processing or "soft handoff" between the satellites and the terrestrial repeaters. Heck, even your posts the other day stated this: So as you look at our SAC guidance for the year of $110, what you can safely assume is that the SAC associated with our retail products is substantially less than $110 and the SAC associated with our OEM products is higher. " Message 22842735 So if the manufacturing costs were so much larger as you suggested, as defined by the technology issues, then those SAC costs would be much HIGHER. But, your "bunk mate" keeps posting his SIRI self-calculated CPGA numbers in the $200 dollar range. So I am not going to argue that SIRI manufacturing costs may be higher, but that doesn't make up the difference in the apparent delta in the CPGA figures. Especially, since you think that Retail CPGA is lower then OEM. Which just doesn't jive with the numbers presented in the SEC statements. Now if Retail CPGA was higher than OEM.. Then the numbers would make perfect sense. PCSTEL
