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, which takes no longer than 3 seconds. |

As a service to all Radio Amateurs,
the science and technology community and for the general public, this site was created by me on 1st
September 2000 and has been maintained and updated since,
voluntarily in my own spare time, for the benefit of all. It is also
intended to enhance Britain's reputation and to help generate new
scientific innovations. |
