That sucks. Hopefully you can get 119 but no HD feed. Amc3 is somewhat marginal for me. I get ThisTV about 50%Q so Nasa should be doable with the 3/4 fec.

They'll still stay on 137W as Alaska/Hawaii cant see 87W. Reason for moving is solar issues

It said AMC6 is having solar panel issues and NASA is moving to AMC3 Cband Transponder 15 on 1/16/2010

I trust MrMars...If I remember, he is in the satellite industry ;)

I'm gonna go with they're doing away with two feeds as well. I do agree I wish they'd put a feed up on Ku as well simply to give more people access to their programming. But I'm not paying the bill so my opinion doesn't carry much weight :) I guess we'll wait and see how it all plays out.

Well at least a good channel is only moving instead of totally disappearing for a change. Right now 87w is ok on the six footer. 72W is over the top of the house and I'd have to manually move the 8.5 foot Paraclipse...no fun with it's dead acuator. Blind

Yes. Regular ol' 4:2:0 SD for the four channel mux, and 4:2:0 HD for the occasional HD content (which is 99% of the time only on for the shuttle launches and landings) which is the 5th channel in the mux when it is on. The HD content looks AMAZING, even with it being on a mux. I recorded the most recent shuttle landing on my AZBox and did a little editing on my computer...wow. It looks great even after encoding it into MPEG4. Kinda fun to do once you get the hang of it.

It's not that he is in the industry, he's stealing (or repeating) info originally posted in another satellite forum.

As for AMC-7, I bet it will stay because NASA may not want to disenfranchise AK/HI sites where there is no coverage or the look angle is very very low. If NASA wanted to combine full coverage of the two muxes into one, there are a few options on SES WS birds that could have been considered...

Actually, you are, so it should. But getting them to realize that is another matter entirely. :rant:

.....

It's not that he's stealing anything. He was just kind enough to explain what was discussed in a link that I "tried" to post about a discussion on another forum.

I tried to post a link to a discussion in the satforums forum because it referenced the problems NASA was having with AMC6, which was the reason they were leaving AMC-6. I tried to post the url rather than the info so people would see the original, but I somehow had a typo in the link, and it went to the wrong discussion. Someone replied that for some unknown reason they couldn't view the forum, and I still didn't realize that I had the wrong URL, so I didn't correct it (now it's apparently too late to edit). The person who responded with the info was kind enough to summarize the correct post and was simply re-phrasing what was being discussed at Satforums.
The correct URL should have been:
http://forums.satforums.com/SatForumMaster/common/messages.php?bpr=1&msg=15864.1#15864.1
{somehow I had switched 864 to 862???... hope I got it right this time }

The person who initiated the Satforums discussion is communicating with NASA, and they previously requested help from the people on Satforums with respect to the quality of their sat signal, and that discussion is recommended as a place to find additional information about the transition to AMC3. The link referenced in this thread was posted there a couple days ago.
