Oscar 10 Satellite Operation 1984 - 1985

These are some impressions from my OSCAR 10 SAT-Operation between 1984-1985. I used the ICOM IC-211 E for 2m (10 Watt) for the Downlink and the KENWOOD TR-9500 70cm (10 Watts) with a Home-Made Amplifier (50W) for the Uplink. I used the 14-element Yagi antenna from Tonna for (2m) and the 23-element Yagi for (70cm).

A self developed Commodore C64 application was managing my home built automatic SAT Antenna-Moving solution which was able to follow the OSCAR 10 at any time. A home made Pre-Amp controller unit for 20m and 70cm was managing the RX/TX flow for SAT operation.
