Gaston's announcement is posted on the AMSAT-NA web under the title,
"Update on HamTV on ISS". For a direct link to the article see:
http://ww2.amsat.org/?p=2177 ... within the posting there is a link
which may help with receiving HAMTV.
Bill Ress, N6GHZ has provided an excellent article, Low Cost DVB-S
Receivers Suitable For HAMTV Reception, in the November/December issue
of the AMSAT Journal. There is a link on the web page (above) where
you may find a copy of this article.
Bill discusses the DVB-S boxes he tested. He includes a short
description of the RF front-end you'll need.

Hi Andy and Graham,
To provide a "visual" understanding of what the HAMTV spectrum will look
like I have included a screen shot of the HAMTV 2.4 GHz test source
using Digilite and built by Kerry N6IZW taken on my spectrum analyzer.
Note the first two spectrum nulls are at +/-1.3 MHz and approximately
-43 dBc. Hence as Graham point out the spectrum BW is over 2 MHz (2.6
MHz between the first nulls). This will be the same spectrum whether a
"black" picture is being sent or a full video scene.
Now to the question of what you will see with a "wideband" SDR like the
NooElec. I have taken screen shots of what you will see using a 2.4 Msps
SDR (I was using SDR# and the NooElec SDR) driven by Kerry's 2.4 Ghz
test source feeding a 2.4 GHz to 144 MHz down converter (the SDR tuned
to 144 MHz) and run at various input signal levels. I'm putting together
the "report" now but the upshot pf the tests indicated that while you
cannot decode any video or audio, you will be able to detect (see) the
HAMTV noise spectrum as shown below.
Hope this helps clarify what the signal will look like.
Test HAMTV Spectrum

HI all,
To anyone who was interested in a gps unit and you don't hear from me in
the next few hours, it's because all 17 are spoken for.
http://www.flickr.com/photos/n3ykf/12188165324/
A pic of my recent trip to Skycraft.
Did get to visit a fellow in Sanford, His business, Avitar unlimited sells
to the general public by appointment and by way of ebay. Picked up some
headers for my project. If you're looking for quality test gear, dc to
daylight, this guy has it. Didn't spend too much time as he looked busy.
73 es happy scrapping

to the output of a 2.4 GHz to 144 MHz down converter, go to my Dropbox
