ISS Packet Turned Off?


The packet is turned off primarily as a safety measure to ensure that the 
ham radio systems do not interfere with the electronics embedded in the 
space suit.  As you can well imagine, interference of this nature could 
have disastrous effects.  While this would be highly unlikely, the space 
agencies and the ham radio community mutually agreed that the ham radio 
community would not be too effected by a shutdown during the short time 
that these EVAs occur.

Also, FYI, we shut down during docking maneuvers.

I'm not expert, but I'd assume it's because of the potential for
interference with the numerous other transmitters and receivers in
use during EVA's.  Basically it probably bottom-lines at "Why risk
it?".  It's an untested and unknown configuration and no one in space
in a suit would probably appreciate it much if a ham radio
transmitter caused problems for them while they're in a very tenuous
