Your United States weather satellites (and other's, I'd imagine,) downlink
in
the 137MHz range, actually. Using some software and the audio from one
of these passes, you can view the snapshots that you'll see later on your
local news satellite imagery :)

That's the ones in low orbit. The ones in geostationary orbit are
around 1600 MHz, I think. A typical Ku dish might be big enough to
get a signal since the information content isn't high as television
(it's more like a fax, until they go digital soon) but I suspect the
LNBF for that band would be pretty awkward to attach to one.

Also note that it may take 10-15 minutes to get one image (for the 137-138MHz
ones). A while ago, someone made a radio-RS232 converter (and software) to
receive such images. Check the usual amateur radio supply stores.

They are below C band. 1600-1700 MHZ or so.
Typically they use a six foot mesh with an LNA that looks like a
coffee can with a probe in it
