Sergei was very active over South-America and I heard U5MIR talking with several stations from Argentina and Brazil.
I had a pass with 20 degrees of elevation and after a few calls Sergei replied with: "Claudio are you?" because probably he did not believe to listen my call from another part of the World :)
I think Sergei was very happy to hear so many stations sending congratulations and Feliz Cumple to him.
On the latest pass over Argentina at 20:41 UTC NO Packet and NO Voice heard.
Thanks again for the contacts.

Hello All,

Today many amateurs have send birthday greetings to astronaut Sergey Krikalev via hamradio!
I had a internet audio chat with my Friend PY5RX and I could hear Fabiano talking to Sergey.
You can listen the audio QSO via:

Good luck to all others in the world!

The residents of the International Space Station this week unloaded cargo delivered to them last month by Discovery's astronauts, prepared for the arrival of more supplies and repaired a key component of the outpost's environmental control system.

In the fifth month of their six-month mission, Expedition 11 Commander Sergei Krikalev and NASA Flight Engineer and Science Officer John Phillips completed the unpacking of cargo bags transferred to the Station's Zarya module from the Shuttle Discovery three weeks ago. They planned to unload other bags stowed in the Unity and Zvezda modules in the days ahead. All of the unpacked items were entered into the Station's computerized inventory system.
