Phase 2 Hardware

Phase 2 Hardware comprises two multiband transceivers supporting 2 meter (144-146 MHz) and 70 cm (435-438 MHz) transmit/receive and L-band uplink operation. HF operation will also be provided. Power output is 10-25 Watts.

Together with an RF tuning unit, power supplies and a computer, the transceivers are mounted on a Velcro-backed table.

This equipment is located in the Service Module, the crew's living quarters.

Four antennas were deployed by EVA (space walk) and clamped on handrails outboard the Service Module. One of the antennas is 2.5 meters long and supports HF operation.

A documented description of the Phase 2 Hardware is available as a downloadable pdf file: Phase 2 document
