>> The packet system in the Columbus module started to act up late last week, sending only a beacon. The ARISS team requested a power recycle by the crew, and with that power recycle, the packet system appears to have stop functioning completely. Note that this unit has been on-orbit for 17 years. It was launched on the STS-106 Space Shuttle Atlantis mission in September 2000 and was built, tested and certified for flight about 20 years ago.

As far as I am aware, there are none operating in SA. Igates are available on the west cost of the continent, and in the east from VK3KAW - there may be others. Playing around with Igate locations in Orbitron reveals that ideal passes for my SA station are much more limited than might be first thought, confirmed by quite a few years of casual, and at times intense experimenting. I have speculated about setting up my own Igate, but lack of accurate and specific information, along with my only having Windose XP computer(s) free for the exercise has meant that it hasn't progressed beyond an initial more or less successful experiment some months back.
