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. Emanuele, I0ELE Rome, Italy

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.
