Farrell,
HAMTV equipment will be delivered to the ISS in August (TBC) by the
Japanese HTV-4 cargo.
You can check on the web the exact date.
Then we will start the commissioning soon and we will start the
transmissions soon after.
Information on the transmission plan will be delivered on this BB.

Dear Emanuele,
Thanks for the detailed information on the HAMTV stream. Is the
DTV-S equipment aboard the ISS now complete and ready to start
transmissions?
Is there a target date as to when 2.4 GHz transmissions might begin?
Thanks for any information.

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.

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.

Certainly!
You can find the nominal link budget on
http://www.amsat.it/HAMTV_Link-budget-IARU.pdf and all the relevant
information http://www.amsat.it/Amsat-Italia_HamTV_brochure.pdf.
However
* Recommended Antenna gain > 25 dB
* RHCP
* Low noise down converter i.e. Kuhne LNC 25 or LNC 25 TM NF 0.7 dB
* Any DVB-S Decoder which can decode a 1.3 MSym/s TV signal
