  • Same, man. I like it, from the meditation-like state when you take it serious to the gun goes bang part when you are just messing around. But some of the people, man... Where do I start.

    I think I should go again regardless, if everyone with wane opinions leaves, that would be surrendering.

  • Seid ihrauf 145.5 MHz QRV?
  • Zuhause in der Regel nicht, da bin ich höchstens auf dem lokalen Repeater und der OV-Frequenz. Im Urlaub und unterwegs versuch ich eigentlich, mit einem channel in 145.5 qrv zu sein. Hab aber nicht viel Aktivität beobachten können, leider.

  • New radio day
  • As a rule of thumb, everything Japanese is expensive but rock-solid. Chinese stuff is hit or miss, don't buy if you are not willing to put in some research. So, great beginner radio.

  • What seemingly backwards solutions have worked for you in life?
  • I found a bug by slacking off.

    Without details, there was a product that we were supposed to test before it hit mass market. It had an annoying bug where it would forget certain configuration items, seemingly at random. Nobody could reproduce it.

    Until me and my friends decided that this was the perfect opportunity to slack off, and took a >1h lunch break ("can't be online on teams, I'm testing..."). As it turns out, the product goes into deep standby after >30 minutes. Official break time was 30 minutes. So if you take the break on the dot, it will never go to deep standby, and never forget its configuration.

    So, we figured out the bug by taking a long-ass lunch break.

  • What's your best tip or hack for camping?
  • Mine is a small mokka/Turkish coffee pot with a removable handle. On a recent trip, someone bought a portable espresso thingy and it was a really nice alternative to the bottom-of-the-shelf cheap instant coffee we had otherwise. But to be honest, non-terrible instant coffee is fine for me, just don't get the ultra cheap crap.

    At the end (or rather beginning) of the day I settle for "hot, caffeinated, does not make me want to spit it out". I'd rather drink the shitty cheapest possible instant coffee on a cool trip with nice people than the other way round.

  • What's your best tip or hack for camping?
  • Coffee. If you are a coffee drinker, get a way to make half-decent coffee.

    Or tea, or hot chocolate if you hate caffeine. Nothing beats the feeling of a hot cup of something after a short, noisy, miserable night.

  • What was the worst apartment you've ever lived in?
  • Oh wow. Yeah, that is on another level. I remember a court case that basically ruled " you cannot really get rid of the fuckers, having a few of them in an old building is not considered damage ". But 50, holy fuck.

  • ❓ ANC-Kopfhörer?

    Servus, mein Bose QC25 hat nach jahrelangem (fast 10!), heldenhaften, fast täglichen Geräuschunterdrücken den Geist aufgegeben. Und jetzt suche ich nach einem Ersatz. Hat jemand von euch gute/schlechte Erfahrungen gemacht?

    ANC, Tragekomfort, Klang und Lebensdauer sind mir wichtig, der Rest ist mir ziemlich egal. Preislich <500, weniger ist natürlich besser :)

    Bonus-Points für gute Teileverfügbarkeit, Reparaturfreundlichkeit und ggf. das ein Teil vom Geld nicht ausschießlich in China landet.

    Flugfunk auf 27 MHz??

    Hallöle, ich hab da mal ne Frage.

    vielleicht weiß ja hier wer weiter. Ich hab mit einem von diesen Quansheng K5 im Auto mal den CB-Bereich gescannt.

    Wer die nicht kennt, das ist so ein China-Walkietalkie a la Baofeng, aber dafür gibt es custom Firmware, und dann kann das plötzlich auch zB CB-Funk hören.

    Jedenfalls, auf 27.144 MHz AM hatte ich in NRW auf einmal statt Truckern Piloten im Ohr. Den ATC hab ich leider nicht gut gehört, aber die Flugzeug-Callsigns passten zu denen, die laut flightradar24 gerade über mir waren.

    Jetzt frage ich mich, warum ist da Flugfunk mitten im 11m-Band? Oder spinnt mein Quansheng und die sind eigentlich bei 27*5=135 MHz oder so?

    Testing a weird antenna in the park

    > How do you test your antenna idea? Well, our approach was to get a portable network analyzer that can show received dBm, put a commercial antenna on it, and strap the whole thing to a PVC pipe (for insulation and to get repeatable height). Then, zip-tie a cough drop to the PTT of a walkie talkie set to low power, so that it transmits continuously. > > Now you can walk around your contraption with your Drain Pipe of RF measuring, and get a (rough qualitative) idea of how the pattern looks like. Much to my surprise, it actually worked.

    Technically, it didn't count as a SOTA :(

    Picture from a hike back in January. I need to go outside more often ;)

    My first magnetic loop for 2m :)

    Really simple construction: bent ca. 2mm brass pipe soldered directly to the outside of an SMA plug, inside of the plug soldered to the red wire as "input coil". Tunable by squeezing the ends more or less close together.

    SWR of <1.2 at resonance, not bad. Impedance is at roughly 44+j2 Ohm, also not bad for totally eyeballing it without any prior calculations.

    I can reach the nearest 2m relais just fine at 2W, although to be fair I can do the same with a short whip antenna. More testing to follow. Holy shit, this actually works!

    Pick some unrelated lectures, they said.

    It will widen your horizon, they said. And here I was, foolishly thinking I could get away with half-assing statistics during my degree.

    Based on a true story

    Turns out the status quo of Linux memory management somehow works pretty damn okay, nobody seems to really know why, and nobody cares.

    A human on earth. Ask me about weird tech. Bonus points if it radiates.
