During 1996, a group of amateur radio operators involved in the communications with the MIR Space Station, decided to join into the "Mir Fan Club". In a very short time over 1200 enthusiasts from all over the world asked to participate, including Cosmonaut Valery Korzun, while leading crew #22. Nowdays MIR is not flying anymore, but here we are again with the same spirit and the same enthusiasm for the ISS, the new International Space Station.
Looks like they ran the first session on Thursday (April 14) in PD180 starting about 15:00 UTC and ending at 18:00 UTC. The second session is scheduled to start about 14:00 UTC and end about 19:00 UTC on Friday (April 15). Looks like we will have to wait and see if they stick with PD180 or change to PD290.
