erecting first 70cm stack some hours ago and now running after some problems.

@f5len tnx. Looking forward to work you.

@DM7Agang @dh5fs @dm3jan GL!

This year @dh5fs and @dm3jan from @DM7Agang will join #OK2A in October U/SHF-Contest. QRV on 70/23/6/3cm with high power. First impression from building up 23cm today:

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

DM7A is running in marconi contest from JO60OM. (4x5el. + 4x5el. + 15el JXX + legal limit)

Laser decapping is beautiful to watch

New open source tool for LTE, GSM and 3G mobile radio monitoring and protocol analysis in Python: QCsuper labs.p1sec.com/2019/07/09/pre… #LTE #GSM #Security #MobileRadio

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

@dh5ym Ist zufällig noch meine Regenjacke dabei?

Last hours at work. Packing, sleeping and night driving 500km to JO70UR for the contest with SN7L team. Are you ready for subregional field day VHF+ contest this weekend ? @Sq3Swf @DR9A_team @sp5xmu @Team_SN7L

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.
