Once more Triebenberg

I was once more QRV from the Triebenberg in JO61XA. The activity was a bit sobering but at least the wheather was nice. I got 13 QSO with a ODX of around 100km. Surprisingly there were some local stations active in FM on 1297,5MHz. The week before the contest i modified the transverter to solve the thermal problems with the built-in PA. This works quite well now without running away 10kHz anymore. Additionally i repaired an old 16Ele Yagi i got from DG2DWL. This antenna is around 6dB better than my old bi-quad. The biggest surprise came 15 minutes before the end of the contest. A beep from the voltage converter that supplies the antenna rotor told me that my car’s battery was empty. No chance to start the engine anymore. It was the first time i was happy that there are so much people hiking at the Triebenberg (and of course coming by car beeing able to help me starting my own one) ;)

Hear you next time !

Laser justification unit

In order to get the laser communication unit justified for the correct direction it is necessary to have the possibility for fine adjustment of horizontal and vertical angles. I made some progress in building a unit that can be mounted onto a tripod and will cary the laser transceiver in the future. Find some pictures attached below. It’s not finished yet but the horizontal adjustment works fine.
