While the antennas were being dismantled in JO60OM, another part of the crew visited #F8KID in #JN38. Thanks for the nice tour to the impressive equipment. :) #vhfcontest

Leider wurde die HAM RADIO 2020 wegen der CoVid-19 Pandemie abgesagt. Somit gibt es dieses Jahr auch kein HamCamp 😢. Merkt euch gleich den Termin für die nächste HAM RADIO: 25. bis 27. Juni 2021 @MesseFN @DARC_eV @hamyota #hamr #DARC

Time to test the first 8x8 Butler beamforming network for 435 MHz satellite tracking and other experiments. The antennas will be here in a week. Will build a 64 beam 4x4 array initially. At 1.4m x 1.4m should be easy to transport. #PhasedArray #satellite @amsat #radar

For the German language readers: @MouserElec pulls a captain obvious: "SDR erhöht die Flexibilität der HF-Kommunikation". Who would have thought that? I mean, 20 years ago, that might have been "news". But in 2019? lol.
