HamTV - Houston Power Point slides http://www.amsat.org/amsat/ariss/Meetings/2011_Houston/Presentations/11%20Pr...
Some addition information plus a video of a presentation given by AMSAT-Italia (video in Italian) is on the ESA website at http://www.esa.int/About_Us/ESRIN/Radio_hams_at_ESRIN_with_AMSAT_Italia/%28p...
I understand the HamTV equipment will be carried to the ISS on the ATV 4 spacecraft currently planned to launch on June 5.
BTW Italy also has an Astronaut Luca Parmitano KF5KDP heading to the ISS. Luca is planned to launch from Baikonur in Kazhakstan to the ISS on May 28 and is also mentioned in his post - USA High School Student’s RocketHub Project http://amsat-uk.org/2013/05/11/high-school-students-rockethub-project/

The HamTV.pdf gives the link budget, looks like there's 7dB of coax/connector losses to overcome between the ISS transmitter and the antenna. That document indicates a 90cm dish should be sufficient.
I believe that it's going up on ATV 4 which is currently slated for June 5.
