EVA for ISS Ham Radio System


One of the ISS Ham radio antennas are expected to be deployed tomorrow, 
Friday January 25.  The antenna that we expect to be deployed is designated 
WA4.  If you look at the end of the Service Module, this antenna is located 
in the 2 O'clock position, where 6 O'clock is down (Earth Pointing) and 12 
O'clock is up.

Cosmonaut Yuri Onufrienko and astronaut Dan Bursch will participate in the EVA.

I have provided the detailed timeline for the EVA on the amsat.org web page:


Also, an on-orbit photo of the antenna to be deployed is shown at:


The following paper has some great pictures and diagrams which depict the 
entire ISS Ham system, including the antenna systems.  This paper is 
probably big for some that have low bandwidth internet capabilities.  The 
file is about 800K.


The EVA is scheduled to begin at around 15:35 UTC on January 25.  The 
antenna system is tentatively scheduled for mechanical deployment around 
17:38 UTC.  Cable routing, RF connection and photo documentation 
tentatively scheduled to occur around 20:29 UTC.  Please note that the EVA 
schedules are very fluid, so if you want to view the deployment on NASA TV, 
you need to stay attentive during the entire EVA activity.

It is not very often that ham radio participates in an EVA so ENJOY!
