"The larger dishes especially are useful for receiving free-to-air satellite TV. One of the main satellites is Galaxy 28, which has programming from all around the world. There's also live "newsfeeds" and sports feeds. You'll need a free-to-air DVB receiver for these, ideally today one with HDTV capability (feeds are often in HD now)."
Yes!! That is what I have done for the last few years now. Found the dish at a flea market (now out of business

( and two LNBF's at a hamfest the weekend after. The PS dish *works* for C-band, but is far, far from optimal, being designed primarily for K-band reception--you'll likely need a BUD if you want to do any serious kind of C-band reception.
As for the Primestar box itself....................................hmmmm....................................................... *scratches head*
"Now DCII (even with updates through the years) seems to be going out of fashion in favor of more universal MPEG-2 / MPEG-4 formats."
I can see why--as I understand it, the ATSC system is based in a large part on DCII technology...ergo, most of the DCII standard that was at one time proprietary is now pretty much public knowledge. Why would anybody want to use a supposedly proprietary scrambling system that even an amateur with a really decent grasp of the ATSC's underlying technology might compromise?
Yeah--software-based CAMs are awesome ;o) *sinister laughing*
