This would be wrong. Why does everyone think that 61.5 is for the east coast only? Remember VOOM used this slot when it was a DBS company, most of the USA could see it including most of California and Wasington state.
Again wrong. New uplinks are inplace and existing uplinks have been updated. There are FCC filings on this.
I doubt it, and if it was true someone should notify Sea Launch who is currently gassing it up to go.
I can get 61.5 in Southeastern Idaho pretty easily. My Dish was pretty low to the ground though...
Please don't mix encryption and compression algos. When MPEG-4/AVC/H.264 compression of HD video is common for both providers. encryption is the key.
Nagravision against in-house DTV/NDS.
Bandstacked signals from a single orbital slot only requires a power passing splitter. No Diseqc commands involved at all.
I was correcting a previous assumption that had the radius of the Clarke Belt at 22,236. The center point of the radius would be the Earth's core, not the Earth's surface. Your 22,236 is not the radius either.
Okay SMith , What ever. I really don't know the difference between encryption or compression , but the point is that both providers use different platforms and in order for both providers to share locals they would have to be on a common alike platform. IF they could do this for locals it would be great but I don't see them doing this unless all mpeg 2 receivers were upgraded to mpeg 4. Then the 4 year time frame for all 210 dmas to have hd locals would make sense. THey could then pick a common satellite to use like 110 or 119 that both companies share and use if just for locals in hd. THey could then do all locals in the dma in hd or digital like the fcc wants.
Sounds good, we are only 581 feet apart. Pretty good for that distance.
Try 26,199 for the radius. Earth's diameter is 7,926, so the radius is 3,963. So 22,236 + 3,963 = 26,199. I don't know trig so it would be interesting to see what the answer is with the new radius.
Co-incidentally: 68.588743 miles (~68.59
) Trig works pretty well with a small angle at satellite distances.I don't see why it can't see the entire USA. The Damn thing is right under us over South America.
I think your formula should actually be:
tan(0.15) * 26,236 = 68.7 miles. (The two distances are at right angles to each other.)
For that small of an angle, though, the sin and tan are almost identical, so your formula still worked. Good way to solve the problem, though.

Alaska and Hawaii are below the horizon. The NW also has a problem with it being low to the horizon, making a lot of locations unable to see the satellite. It is very far east.
The elevation in the SF Bay Area is 14 so it's very low in the horizon. I got lucky and was able to get it with very strong readings but not everybody in the West coast is lucky enough to get 61.5.
I see! Question though? Why can't they move it more west on the equator? Then it could serve the entire lower 48 ? Right?
I need to feed a 622 and a 722 from 61.5. What's the easiest way to do that with a single LNBF?
Vegas is right! A power passing high frequency splitter is all that's needed to feed 2 dual tuners from a DP Dual LNB (two outputs). Like he said, there are no Diseqc commands involved for a single orbital location so a splitter would do.
Now my question for Vegas is, will the splitter need power passing on both legs, just one leg or it doesn't really matter?

The license is for 61.5 degrees west on the equator. 110/119 are their slots that will cover the entire US. But, too many old receivers point to 110/119 for them to do anything dramatic like change them to MPEG-4. So, the experiment (I mean strategy) is going to be on 61.5.
Dish has DBS satellites at 61.5, 110, 119, 129 and 148
The have licenses for 86.5 and 77 provided they do not interfere with Canada. They have a satellite at 77 pointed at Mexico.
Dish's problem throughout the the years is that they have not had a single plan to provide service. They are constantly changing their minds and what happens on satellites. Who knows if the 61.5 project will work out completely or if they will change it mid stream or end up abandoning it. With Dish you never know.
Ideally they would have spot beam satellites at 77 and 86.5 to provide HD locals without interfering with Canada DBS providers, and use 61.5 for all the national channels. This would give them most of the lower 48. But, they bought the spot beam satellite at 61.5, so they are putting spots there.
They could change 110/119 over to MPEG-4 but then they would have to spend billions to update all the receivers.
DIRECTV built new satellites for new slots. Those wanting to see the new satellites have to upgrade the receivers. The existing receivers continue to sell the old slots. DIRECTV appears much more organized with a single dish solution able to see all their satellites.
Thank you. You hit it right on the head. I think what they are doing is very needed and exciting and eventually all will benefit. But for a lot of people north of SF the results will come sometime after the benefits to the rest of the country.
