  • Test of a QO-100 station

    At our meeting last Tuesday we tested the QO-100 station of one of our members.

    On the roof of our station we put up a parabolic antenne (a 50 cm satellite dish) with a tripod facing south. The active part of the antenna system consists on the RX side of a modified satellite LNB that is being fed from a waveguide, and the 13 cm TX antenna is mounted coaxially to it. As no TX capable SDR was available, we focused our efforts on testing the RX side.

    With a HackRF we were successfully able - after some effort - to receive SSB and CW signals with good SNR.

    In the future we wish to put effort into building a permanent QO-100 station with a larger dish to be able to have receive and transmit capabilities at our station.

  • Participation in the university group fair

    On the 2nd of December 2024 we had two stands as part of our efforts at KIT's university group fair:

    One inside stand, with general information about us and about amateur radio, as well as a SDR-Livestream and some antennas; and one outside stand, with a portable HF radio station with an inverted-v antenna.

    We were very happy about the clear resonance at the fair, and hope to soon welcome new members.
