Video of VO-52 Downlink Over Europe

Dimitrios Pallis SW1JGW has made available a video of the downlink of the amateur radio satellite VO-52 over Europe on May 27, 2012.

Among the stations heard in the downlink is Domenico I8CVS. His interest in satellites first started in 1960 when he built a VHF converter and yagi antenna to succesfully receive the 108.000 and 108.030 MHz beacons from the passive communication satellites ECHO-I and ECHO-II.

Dimitrios SW1JGW made the recording with a G59 SDR and Ten Tec 1012 Transverter.

How to work the SSB amateur radio satellites such as VO-52
