We thought, why not build a temporary 1x4 array out of F9FT 9 Element Yagi Antennas for fun @dk0tu. This is our result. Together with @DL7LL and DM4GO.

Thank you @SatNOGS team for our hackathon during @fosdem last week in Brussels. Even if there's still a lot to improve, we managed to integrate @SALSATmission ~5 months prior to its scheduled launch in June. We're looking forward to test it on other @TUBspace-crafts until then.

Life is too short for QRP, that's why I designed a 100W PA for the Hermes-Lite 2, based on the @NXP MRF-101 :) Still some work to do left (heat sink, case), but so far it's looking promising!
