Andre Kuipers ISS contact
On the 12th April about 20:00 pm 2012 I had a brief contact with Andre Kuipers in the ISS. Although my AZ-EL rotator of Alpha-Spid was not working at the moment I could reach him in the ISS. I had to adjust the frequency manually to compensate for the doppler effect. That is why he could not understand me in the beginning of the QSO. My callsign at that time was PD5DP.
