** The amateur radio station located in the Columbus module is currently operational with the UHF Ericsson transceiver and packet system using the frequency of 437.550 MHz.
To utilize the the packet system, operators need to set the UNPROTO path to ARISS (the id is RS0ISS) for digi relay or they may connect to the BBS using the callsign RS0ISS-1.
The packet beacon is set for 2 minute intervals so it may not appear to be active over many parts of the world but keep listening and mind the Doppler shift (+ or – 10 KHz).
