During the long Corona time... i start thinking about the QO100. is it interesting for me to work via a space repeater station? How will be the way of operation, just a quick confirmation of signal reports? Well.. me interest in the tracking and working of the LEO satellites came also back after long, long time... so i started to see it as on project to “ Go satellite” ... one antenna system for the LEO and another dish for the QO-100. Maybe i am a user who was more often in Doha very close to the base station than has QSO via the Sat.... but here we go... and lets catch up I had some good recommendations from my old radio friend Charly DK3ZL and some others.

Very positive experience... on a sunny Sunday afternoon we (my radio friend Kevin and myself) installed all the dish and equipment very quick and simple to the sunshade stand and tried.. 155° and some around 30° elevation ...and... I heard the CW signal. Some find adjustment and we heard the first QSO from the QO100... 37.000 km away.. on the first attempt... that was a great motivation! |

I am using the QO-100 equipment by bamatech for the LNB and Kuhne DB6NT for the Up-and down converter technology. The dish is a 85cm Technisat dish. Many thanks to Kevin and Ramona to “customize” the dish for me with my call sign. After connection to the 10MHz reference signal source I had a 100% stability of all down converted frequencies.

My “Ground station” for the QO100 include a IC 705 as receiver and a FT847 as transmitter for the uplink. FT847 goes with 144 MHz into Kuhne and with 2400 into the LNB. On the rood the LNB send 10GHz into the downconverter and 430 down into the shack. |

First day ever on the QO100... and first QSO with Charly DF3ZL who gave me a lot of suggestions and inspirations with his QO-100 tour cross the sub Sahara Africa. Second QSO was with my colleague from the Robert Bosch Ham Radio network, Nina, DL2GRC The ICOM 9700 is just in use for the LEO operation, not for QO-100 |

Great thanks to my friend Michael, DJ2VA, who created a dashboard for the Kuhne converter to have all the parameter under control. My original idea is to install the converter later close to the antennas under my roof. So I would need a tool to control the status. Also many thanks to the good conversations with the team at Kuhne for some hints and support |
