I spent quite a few evening hours this past week modeling the production Morserino M32 Pocket case in FreeCAD. The original had basically been forked in a mesh editor, which made it hard to work from. Hans (of QRP Labs) kindly released his STLs, which made this work easier and the resulting objects better.
If you want a different color, or different plastic, or to make a modification to the design, you…

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…

I just finished¹ building a QRP Labs QMX this weekend, and after a few tests, tonight I got on the air with it and made my first QSO with it. All the way to the Kansas City, MO area, with AK0A Ken. Using a radio about the size of a deck of playing cards. The radio is smaller than the USB power bank I was using for power. 🤯
¹It triggers SWR protection transmitting into a dummy load, so I guess "finished" is modulo taking it apart and rewinding the transformer that senses SWR. But also I…

The case for my 28g QRP dual-ported (9:1 and 49:1) unun cracked from tightening one of the terminal screws too tight, and from having printed the box with too few perimeters, so it wasn't really strong enough. I had designed it so that the coax was integrated into the case, so I had to cut the case apart to remove the still-functional electrical components for re-use.
At least this gave me a chance to confirm that I hadn't blown up the ferrite from overheating it!
