    40m came alive in the last hour, as we started to get close to evening, and as 20m was frankly played out.I was going to plug my rig into battery, but then saw in the rules that your computer has to be on battery power as well, and I didn't have a way to plug my shack computer into battery, so I didn't bother running the rig off battery.Then when I went to submit my log, I saw that actually your logging computer can be mains powered, so the rules must have been about the computer you are using for digital modes. Which I wasn't. I did all CW, no multi-mode multipliers for me!So I could have gotten another multiplier for my 2-point CW QSOs for my solar-charged battery, as well as the 4x QRP multiplier. I could have had 510 points instead of 408 points. Which doesn't matter at all because I'm not actually in any form of contention for anything; I worked only about five hours thanks to all the winter storm prep. And even if I'd worked the whole time I still wouldn't be competitive. I only hunted, I didn't run.And running only 5W, I didn't even make the antenna wire warm enough to melt the ice that was covering it.Maybe next year I'll run instead of hunting. But probably still QRP, and maybe actually in the field...#WinterFieldDay #HamRadio

    Today I released version 0.7 of my print-in place single-paddle Morse code key.

    Today I released version 0.7 of my print-in place single-paddle Morse code key.This will function as release notes:The most important practical change is that the slot in the lever for the stabilizer bar is taller, so that it doesn't bind. Previously, it sometimes bound depending on luck, and when it didn't bind, needed to be greased with a light lubricant.The most important user-facing change is updated build instructions, now with pictures. Previously, the instructions were just text.The most important developer-facing change is that it was rebuilt with FreeCAD 1.1RC, and all recalculation errors and warnings were removed. previously, it had quit building correctly due to changes in FreeCAD.The side contacts are better aligned with the common/ground screw in the lever when using thin ring terminals. (It was previously optimized for thick terminals.)The rear stabilizing bar was never necessary and was just extra weight and ugly complexity, so it has been removed.The spring radius is no longer an explicit parameter.I added more links to sources for hardware.This is getting close to what I would consider a polished, 1.0 release.As always, I crave feedback. If you build this, I want to hear what went well and what, if anything did not.#MorseCode #HamRadio

    We had a surprise opportunity to go to the beach this weekend, near Southport NC.

    We had a surprise opportunity to go to the beach this weekend, near Southport NC. I have the weird preference to sling my hammock under the house, between the clotheslines, instead of sleeping indoors. Half camping? I use a big rubbermaid box as my "suitcase" and put my shoes on it overnight... It was cold at night, but an underquilt and reflecting bubble insulation in the hammock, with an inflatable mattress on top of my down sleeping bag, kept me cozy.My wife and I went to Fort Fisher State Recreation Area and set up a pair of #HamRadio transceivers. Because this weekend was SSB CQ World Wide DX contest, she couldn't find an empty space to call CQ, and had trouble breaking through pileups, so after a few QSOs she decided it wasn't fun any more and read a book. It was not the CW CQ DX contest weekend, so I successfully activated US-3842 with Morse code. Then back at the beach house, I kept ducking out onto the porch to hunt #POTA operators using CW, with a 33' random wire antenna hanging from a spiderbeam pole, connected to the 9:1 port on my tiny little homebrew QRP dual-port unun. One of those QSOs was with the ham who sold me my KX3 that I used to make the contact! ๐ŸŽ‰I gave the random wire a workout with QSOs on 40, 30, 20, 17, and 15 meters. Tried hunting with no luck on 80, 12, and 10 meters.The wind eventually broke the antenna wire off the terminal, so I'll want to fix that before going out again. But at the beach, it was easy to bodge that by stripping back a bit of insulation and screwing the bare wires in the terminal.

    In order to 3d print a little amplified speaker box to use for #HamRadio SSB 2-operator POTA with my wife, I want to model components and then model the box to go around them.

    In order to 3d print a little amplified speaker box to use for #HamRadio SSB 2-operator POTA with my wife, I want to model components and then model the box to go around them. I found a speaker on grabcad that is only a few mm different from the speaker I found in my bin. Just different enough that I need to start over to create a good basis for my box model. I didn't bother constraining everything perfectly when modeling the steps in the metal shell, and I didn't model the cone accurately because those really don't matter that much. It's good enough to check for interference.I have barrel and XT60 power connectors already modeled from my last project to choose from here, but I need to add models for the 3.5" phono jacks and the TDA2050 amplifier board I bought from Amazon. Trying to decide whether to use that completely as-is or desolder the potentiometer for the volume control and use wires to re-route it to a more convenient place. A model might help answer that question.Not quite #FreeCADFriday unless you give me about 22 hours of grace. ๐Ÿ˜€
