Lite ny information om radiokonfigurationen på ISS:

Kenneth, N5VHO, Project Engineer for the ARISS Program, reported this week, "Some short term reconfigurations to the Kenwood radio were attempted on May 21 with limited success."

Kenneth described progress aboard ISS as, "The preset channels that are used for many of the day to day operations are still inaccessible. The good news is that a few of the more commonly used configurations were able to be stored in the radio. One of the modes that was able to be partially restored was the packet system but the operations will be on 145.825 simplex. General voice communication as well as configurations to support school contacts were also saved."

The ARISS team continues to work on a solution for a full restoration of the radio which is required to return full functionality of the radio system. This process will require access to a computer system and certification of the required software. This request is being worked with all necessary international space agencies so it is thought that it will take a significant amount of time to get all parties involved satisfied before the actual restoration can occur.

In summary, the current ISS radio configuration being tested includes:

• 145.825 MHz simplex is for packet operations only.
• Voice frequencies have not changed (144.490 up and 145.800 down for ITU regions 2 & 3 or 145.200 up and 145.800 down for ITU region 1)

In closing, Kenneth wrote, "In the mean time, enjoy the packet operations when the crew is unavailable and keep listening just in case one of the ISS crew decide to give out a ‘CQ’ over your part of the world."
