And IIRC, the downconversion is handled by the LNB (Low Noise Block
Downconverter) mounted at the feedpoint of the dish.

Don't think so.
Most DVB-S receivers require input of 900 to 1600+ MHz or something like
that.

Would the "K5GNA" Transystem downconverters work, the ones left over from
AO-40 (sobsob)? Still have the L & S band stuff in moth balls, just
waiting, waiting & waiting.

Hi Les and all,
I would not jump into any kind of advanced purchase or antenna assembly etc
on the ISS TV program at this point.
1. It will take considerable time to get the equipment up, installed,
tested, verified etc.
2. If the primary use is for ISS school contacts, you are limited to
scheduling, ISS visibility at your location etc.
3. Downconverter options are very limited right now since they have to
match the DVB-S receiver input frequency.
4. Limited choice of 1m+ dishes with LHCP antenna feeds tuned to the
proposed ISS frequencies.
All of this will change over time once more information becomes available
and folks/vendors are starting to look into this and more products/tools
become available. Also, there might be a more permanent feed of video not
just limited to school contacts. We will see.
Will be very interesting to see/hear what info is made available during the
Dayton AMSAT forum by Frank Bauer on ARISS.

First of all congratulations to the entire Fox team. I know that everyone
is excited about the possibility of another FM bird in the near future.
As for Ham-TV, I agree that more information about the ground station
requirements would be most welcome. I just managed to win a TechnoTrend
S2-1600
HDTV satellite PCI Card on ebay ($60 bucks with shipping) so I hope this
is a good start on a complete station.
The next hurdle for me will be assembling a workable antenna and I assume
an AZ/EL rotor with automatic tracking? It does seem like information is
incomplete
considering how close to the go live date we are. I know that this type
of
digital TV is in wide use in Europe, so maybe some of these folks can
lend
the yanks
a hand?
