Please do not attempt to connect to the old International Space Station Packet BBS system, callsign RS0ISS-11, as you will block the whole 8 minute pass for all other European stations who can digipeat only if the BBS is not being used. The BBS was established many years ago before the advent of e-mail, the crew DO NOT READ IT, and in order to obtain a QSL card from the ISS you only now have to now digipeat once through the ISS using the callsign RS0ISS-4, which takes no longer than 3 seconds.
