ABOARD THE INTERNATIONAL SPACE STATION (ISS)
The current ham equipment (summer 2005) consists of two Ericsson HT's: the M-PA VHF , M-PA UHF and a Kenwood TM-D700E. They also have packet capability with a Pico-packet TNC.
For ham operation, the redundant "Sirius" antenna was used initially (originally used in the 147 MHz segment for launch telemetry). They now have dedicated ham antennas installed.
