For the digital TV challenged, what means "Any DVB-S Decoder which can decode a 1.3 MSym/s TV signal"? How would I know if I have such a thing, or what I would need to get if I don't.

HAMTV stream will be transmitted at 1.3 MSym/s or at 2.0 MSym/s. Technical specs of the set-top box indicate the range of the decoded stream. Generally this range is from 2 to 45 MSym/s, therefore if you need to buy it, you should select one that can guarantee a range from 1 to 45 MSym/s.

Hi Emanuele,
Right. But what is that in terms of what normally gets described? For example, I have a Digital TV card for my computer (Pinnacle PCTV HD). It says it does "ATSC digital TV (HDTV up to 1080i, and SDTV)" and "Clear QAM (unencrypted digital cable)".
Am I even close?

Hi Greg, I believe that your Pinnacle PC Card is not for DVB-S (Satellite networks) but for DVB-T (terrestrial networks). Please check on the web or give me the model of your card, so that I will check it. Emanuele I0ELE

Ah, that is probably right. Model is PCTV-800i; it's definitely aimed at terrestrial stuff. Now I know what "-S" means...
Would there, by chance, be a decoder for the FunCube Dongle (or other USB thingie)?
Thanks for the help,

I would like to know how often this is even going to be in operation before I make myself crazy trying to piece something together.

Hi Dave, this will be normally used on the occasion of ARISS school contacts. However ARISS intention is to have the video on for long periods with still or live video material. Emanuele I0ELE

Thanks Emanuele,
The last part of your message is actually the most important part. Watching the ISS astronauts talking to schools and having a video feed is great. However, looking at schedules and available downlinks for NA and or Europe, they are limited and might not really much worth of an investment for most ham operators. On the other hand having a more or less constant feed like the APRS would be outstanding. In addition, it would be even better to have the system connected to an outside pointing camera to get constant feeds on the earth while the ISS is flying overhead. That's a huge incentive, at least for me. Hope that is in the plans somehow.

If the feed is only active for schools contacts it's going to be an expensive ham activity as most of the equipment needed is going to be fully dedicated for this and the schedule is going to be VERY limited.
Even if it sounds very attractive ... if there is not a permanent feed, I will have to see the videos on YouTube :-/
