Amateur Radio Ericcson on ISS

There are currently two (2) Ericsson Amateur Radio transceivers on board ISS. One is configured for the 2-meter band (144 - 146 MHz) and the other for UHF (435 - 438 MHz). The 2-meter system is currently being used for FM Voice links and is connected to the Sirius mono-band (147 MHz) antenna mounted on the FBG module. In the near future, some of the Amateur Radio equipment may be re-located into the Service Module with access to the new set of Amateur Radio antennas installed in 2002. Most of the original hardware for this project came from the SAREX/ARISS amateur radio project for the Space Shuttle program. The Ericsson radios were used extensively from 2001 - 2003 as the primary Amateur Radio link for School Schedules and random voice contacts on the Amateur Radio bands. In December 2003 a new Kenwood D700 radio was installed as the primary Voice/Packet Amateur Radio. The Ericsson Radio will still used for other projects in the future, including UHF Slow Scan TV.

Push to Talk button: Controls the Ericsson transceiver	Speaker kit: The existing Phase 1 system does not support an external speaker port. The ISS crew requested a speaker connection so that other crew members can also listen. The new cable adapter (small blue box) will be flown on a future mission. The speakers are already on ISS	VOX SSTV adapter: Sergej Samburov (L) and Lou McFadin are shown holding the new VOX SSTV adapter. This using will allow SSTV and other VOX operations.
