The SAREX hardware will be flown in configuration B, voice-only,
battery operation, since no shuttle power could be spared for SAREX
on this mission. The SAREX equipment aboard STS-83 includes the
Motorola 2-meter FM hand-held transceiver, 15 spare batteries, the
window antenna, SAREX headset assembly, personal recorder and the
required interconnecting cables.

The SAREX team is also flying the Heathkit packet radio TNC for
possible use later in the flight. If power conservation measures are
successful, the mission control team will advise SAREX and the
astronauts to initiate use of the packet radio system, which also
includes one of the Shuttle Laptop computers.
