How to tell how tall a tree is
1) At a distance,bend and look back through your legs
2) Adjust distance until you can barely see the top
3) Height is your distance from the tree

⚠️ Assuming we look through our legs at 45° - accuracy might depend on the observer's flexibility!

3 days left until the launch!
The launch will be streamed live on YouTube and there will be an event at TU Budapest (BME). Stay tuned for the details.

Below is the 4.5m parabolic dish at the Ground Station.📡

@Afelia Dann bleibt aber nur Nuklearenergie übrig. Das ist wenigstens gut fürs Klima.

@XFAB_FOUNDRY We was there too with a #satellite @qo100_sat ground station with @ADI_News #plutosdr transceiver and had a lot of visitors. And we had about 20 QSO to demonstrate our P4A SDR TRX system. Had a lot of fun in the FAB too.

F6BVA S/X band feed for QO100. Next step : measurement.

#QO100 my qo100 mobile tranceiver is nearly ready. Still waiting on AD9851 dds to complete the project.

@ZhaoFen37759626 @f5len Only because he/she is stupid. No more thinking abut that. Just ignore. You have no chance to catch him. Thats why maybe better not to recognise or listen that shit. Just, ignore. Hard but that is your only weapon...

@I0LYL @amsatdl @AmsatUK Sadly not everybody understand that same like you... Simple ignore it. That's the best what we can do.

A demonstration of the conservation of angular momentum using a Hoberman sphere. Angular momentum depends on the rotational velocity of an object, and on its rotational inertia. When an object changes its shape, its angular velocity will also change.

@HAM_DM4DS @MeltdownCore Ich habe davon auch vor 2 Wochen paar gebaut. Ich bin damit sehr zufrieden. Nur ich habe nicht geschafft so schön fräsen wie deine Alugehäuse.

Friday on 08.11.2019 #LangenNachtderWissenschaften @XFAB_FOUNDRY @XFAB_Erfurt with @DARC_eV #x09 we will build a @qo100_sat ground station based on #plutosdr from @ADI_News and amplifier from @skyworksinc 66292 and @AmpleonRF pallet.

[tamas_pap @DO1TAM]

@robinlgetz @amsatdl @skyworksinc @AnalogDevices Thanks Robin. I will test it tomorrow.

[tamas_pap @DO1TAM]

SDR TRX in one case for #p4a #qo100 @amsatdl with OCXOs, @skyworksinc preamp and @AnalogDevices #adalmpluto and 20W PA.
