ISS On-Board Hardware



Those that want more information on the Phase 2 system on ISS are welcome 
to copy the paper at:

http://www.amsat.org/amsat/ariss/Papers/Phase%202%20AGM03Final.pdf

As Dave Taylor mentioned, the Kenwood D700 is running 10 watts.  The 
feedline is Russian built and space certified. The feedthroughs, feedline, 
cable and antenna clamps, and EVA responsibilities are a part of the 
overall contribution of the Russian team to the antenna system development.

Enjoy the system and thanks for all your interest in the ARISS program.
