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.

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,

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.

Thanks, Dan. That helps a lot.
Is there something about the DVB-S modulation that makes it astoundingly better
for this application? For something that is intended to be widely received,
they sure are making it difficult...

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

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?
Greg KO6T
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.
Ema
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.
