4:00 the sun is rising. I'm working on incorporating the last last-minute changes.
The birds just started singing oustide.
3:01 ... 6h into the final tweaks on my master thesis. I see little moving withe spots in my peripheral field of vision. Also I'm running out of clubmate.
6h remain until I'll have to print the final version.
Found my observation for the fourth image.

Software only becomes 'enterprise grade' if, when its behavior is described to an outsider flatly and precisely, the outsider assumes the description is some kind of elaborate joke.
This weird feeling when you know something will be a really close call, but you also clearly see that you can make it and narrowly avoid the catastrophe. And at the same time you also know that there will be no rest until it's over and you'll have to fight through every second of it. That's when I feel alive. That's when I come up with the real awesome stuff.
Not to bad considering I only pointed the antenna in roughly the right direction and used my smartphone to decode the noises coming out the speaker ...
Waiting for the ISS to come back around...
Also if you managed to receive something stop by at https://ariss.pzk.org.pl/sstv/
where you can get an award that entitles you to some #hamradio bragging rights.

Stripped out most of the noise for your listening pleasure: https://files.zenerdio.de/satnogs/satnogs_24393_2018-06-27T10-31-30_clean.ogg
Seems like my SatNOGS station also recorded a part of todays ARISS contact:

Big thanks to fredy for scheduling it after I forgot about it.
You can't convince me this isn't the best way to browse Mastodon.
I'm thinking about buying yet another #rtlsdr to hack it for direct sampling. My idea was to use diplexer similar to http://www.g8jnj.net/softwaredefinedradio.htm#webs-bin-59a6831ae4b09e327b7e5c9b because I'd like to have a stick with a single input that covers everything from a few kiloherz up to 1.8Ghz.
Anyone ever modified one of the cheap sticks?
Is it worth the work or should I just pay a few € more and get a one of those "RTL-SDR Blog V3" sticks which directly come with a diplexer?
Next step is implementing WSPR with the Si5351 and the I might need to find a place to hang a few meters of wire.
After rewinding half my inductors with the correct number of turns, my little 250mW QRP transmitter works.
7.165MHz an no harmonics, at least none the show up on the scope.
Found it ... it was running of the wrong PLL, resulting in one multisynth divider value getting to small and some undefined behaviour.
