On Monday, May 21, Sunita Williams, KD5PLB, was able to restore a few commonly used configurations in the Kenwood radio. One of the modes that was partially restored was the packet system, although the operations will be on 145.825 simplex. Configurations of general voice communications and those used to support school contacts were also saved. A full restoration of the radio is required for a fully functional radio system. This requires access to a computer system and certification of the required software.
