RE: social.makerforums.info/@mcdan
This morning, I heard the first report of someone passing their US ham radio exam by using Open Ham Prep …

Screenshot showing the first 6 of 16 lessons covering the US ham radio Technician class exam material, starting with "Welcome to Amateur Radio". Because I have passed all the quizzes associated with topic 2, "Your Identity on the Air", it is marked as completed. Two other topics are marked as partially complete because I have passed some but not all of the associated quizzes.
Screenshot showing the first six of 57 topics, starting with "The Transceiver - Your Voice to the World". Because I've taken the quiz for the first topic, it is marked as "Completed"
Screenshot showing the result of successfully answering all the questions in a quiz, and that you can always review questions for a topic by re-taking the quiz.
Screenshot of dashboard, showing that answering only a few questions does not demonstrate that I'm ready to take the test, even though I answered all of those few 100% correctly.

Mikroplastik mindert die CO2-Aufnahme der Meere
Forschende warnen: Mikroplastik schwächt die Fähigkeit des Ozeans, die Temperatur der Erde zu regulieren und weltweit das Klima zu stabilisieren.

Oceans struggle to absorb Earth's carbon dioxide as microplastics invade their waters
A new study reveals that microplastics are impairing the oceans' ability to absorb carbon dioxide, a process scientists find crucial for regulating Earth's temperature.

Solar Opposites looks so much like a Rick & Morty look-alike trying to get onto the bandwagon. I'm not sure if I should watch it. Is it good?

Happy #FreeCADFriday! This week I've been working on re-modelling the case for the Morserino M32 Pocket. At least four different people had worked on the case. It was initially made in FreeCAD, but then was modified with other software, and the current case that QRP Labs is shipping was edited in s…

Screen shot of a basic case with no integrated paddles at all. The case is rendered transparent in order to show the internal display frame and the base, as well as some of the internal structure. There is a knob placed where the actual physical knob sits on the assembled device. The internal components are not modeled.
Screen shot that is like the other image, except that the case is the version with the default integrated paddles as shipped by QRP Labs.

Einbau in Waschmaschinen: Filter nach Fischmaul-Vorbild entfernt Großteil an Mikroplastik
Mikroplastik gelangt immer häufiger auch in den Körper von Menschen. Ein Großteil davon kommt vom Waschen und fließt ins Abwasser. Wie die Kleinstpartikel erfolgreich herausgefiltert werden können, schaut sich ein Forschungsteam in der Natur ab.

I finally got out and did a #POTA activation using only my QMX. Most of this was on a 20m EFHW, and then I did a few QSOs on a random wire through a tuner.
It didn't start out well. I couldn't figure out why no one was responding to me. I finally discovered that when I last used the QMX I was showing it to someone at a ham club gathering and had put the CW keyer in practice mode. 🤡 I …
