You may also enjoy the Nova "Secrets of the Sun" show which can be viewed
below. This is a 54 minute long show that does a great job of explaining how the sun works and the new field of helioscience. http://video.pbs.org/video/2226474716/ 73, Bob, WB4SON ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

No even not outside the US, you need to tell the organization in what
STATE you live, so US only and no helioscience for us. And I always thought that science is truly international. Luckily the NASA movie IS visible for the world... 73, Peter, PA0PJE Op 2013-02-26 17:32 schreef David Ferrington, M0XDF: > Looks like it might be very interesting, but not available in the UK:-( ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Hi Ron, the link to the SME works fine, it's the second link (http://video.pbs.org/video/2226474716/) that doesn't.

THanks for the explanation Ron - looks like that link doesn't work in the Uk either.
Oh well, some distant time in future when everything is available. 73 de David, M0XDF For disappearing acts, it's hard to beat what happens to the eight hours supposedly left after eight of sleep and eight of work. -Doug Larson On 26 Feb 2013, at 23:12, Ron D'Eau Claire wrote: > Aha!

Interesting aside...
I worked for an In-Flight Entertainment development firm, and our premier product line was a series of Ku-band sat receivers for EchoStar (Dish). The EchoStar footprint drops off severely at US borders. Dish had a similar restriction to the one that Ron found re PBS. In addition to the signal level problem at the borders, the sats' antennas "hotspot" metro areas, so that smaller dishes may be used in population centers. In the middle of flyover country, a bit more of a ground station antenna is needed to maintain link margin. Link margin and antenna budget being what they are in that business, we developed a steerable airborne antenna based on an array of Luneberg Lenses and it worked well. At least it worked well away from borders and in metro areas... Unfortunately, the System Engineer that developed the antenna specs lived in a city, and far from borders. The EchoStar spec said nothing about the contour of the signal, and how it varied. Link margin as-designed was 1.5 dB (a reasonable margin, so I'm told). So far so good. US air carriers sometimes stray into Canadian airspace, and this depends on the flight plan. US carriers also fly right over the center of the country. We designed with an affordable ink margin, but not enough to cover the contour dips at borders and in flyover country. We got into big trouble with the airlines because of LOS occurring in these two circumstances. This involved a lot of penalty money changing hands, and a lot of free flights for our engineering staff to try to work out the problems (which is when we figured out the variable link margin problem). The amount of trouble we got into when Dish found out about airline passengers viewing US-licensed live content in Canadian airspace cause the earlier problem to fade to complete obscurity however. Live and learn.

I missed the second link. That is not a NASA link. It's a link to a video produced by the US Public Broadcasting System (that's the pbs in the URL).

PBS is legally obligated to ensure each program does not exceed its granted rights, which unfortunately eliminates international streaming ability for some PBS programs in Canada and elsewhere.

The internationally available collection link goes to www.video.pds.org I don't know if that will open for you, or if they program is in there. I suspect that it is not or the other link would have worked. I have the same problem with BBS broadcasts here. Some of the on line stuff is blocked in the US, especially the classical music on line.

Interesting, but let's end this OT thread at this time.
