Try using the 145.975 MHz uplink. According to Chris Jackson the
other one gets deaf when the onboard temperature exceeds a certain
threshold. UO-22 is currently in a dawn-dusk orbit that leads to
increased temperatures.
This is rather unfortunate for the Stanford University/KE6JAB-1 WX,
which was deployed in Antarctica during January 2001. UO-22 relayed
its data to the SANAE IV base (also in Antarctica) until it became deaf a few
days ago.
You should of course appreciate that UO-22 has far exceeded its
design life. It wasn't designed for such an unfavourable orbit.
