DUBUS 06/2017 

During period of DUBUS 10 GHz contest, I was testing setup for EME DX Expedition to Morocco 2017. For comparison with results of DUBUS 2016, I was using same power 30W RF. For expedition I will have new SSPA 52W RF. Main focus was to test new dish 180cm. Comparing with previous dish is new one 1,5dB better. After collimation I have recognize that new dish has only 10mm diameter focus point, what's giving chance to use it also for 24GHz in future. Last test of 10 GHz I will do during short expedition to Poland in weekend 18-20th of August 2017. Follow the page you can see some pictures and changes made in setup. Looking forward to work many of you as CN2R.
