Baby's first unun!
My #AmateurRadio journey continues with making some of my own equipment...
I wanted to be able to connect either an EFHW or an EFRW to my KX3, but move the actual antenna away from the radio, so that I can POTA with other people close enough to talk, while keeping the antennas for the different out of each others' near field so they don't interere. To …

Partially-assembled unun. A nut on the upper right is connected to the coax shield, and is connected to a brass screw on the right for a counterpoise connection. A blue 100pf capacitor is in the upper left of a purple 3d-printed box, connected between ground and the center terminal of the input. At the bottom, the 6th turn is tapped and run to another brass screw which provides the 9:1 random wire connection. A strand of red magnet wire goes up to the upper left over the blue capacitor; it conn…
The internals of the unun with kapton tape covering the torroid, and the 49:1 antenna connection brass screw in the lid at the upper left.
The assembled unun with two wires attached. At the top is a wire next to a ground symbol on the side of the 3d-printed box. This wire is the counterpoise. On the lower right is another wire connected to the side of the box. This is the random wire connected to the 9:1 antenna connection. At the lower left, in the middle of the lid, is the antenna connection for an end-fed half-wave antenna.

Each of the terminals uses a heat-set insert as a finger nut to connect the antennas.

"That is the real reason why Starship was doomed to fail from the beginning. It’s not trying to revolutionise the space industry; if it were, its concept, design, and testing plan would be totally different. Instead, the entire project is optimised to fleece as much money from the US taxpayer as possible, and as such, that is all it will ever do."
Wow, this is an interesting piece..

Whatever you do, do not call the number and recount the story of the time you were working commercial towing and a co-worker’s indigestion turned out to be a chest bursting health hazard that should have been nuked from space. 👽

uspolitics, trump
I keep seeing smart people writing stuff like
> [the US] kept peace through strength balanced with restraint, and wielded influence through culture, values, and diplomacy
I understand that #Trump is terrible and some people feel tempted to idealize what they had before him, but we should be more discerning, or otherwise it becomes impossible to understand how this happened in the first place.
Let's start with some questions:
- peace where? and for who? was it true peace, or "Pax Romana"?
- are we going to take seriously that statement on "restraint"? after all the lies, internal witch hunting, sanctions, coups, wars, invasions, genocides, and last but not least, 2 unnecessary nuclear strikes on Japan?
Now, on "culture, values, and diplomacy". Sure. Why not. Not everything was going to be bad, right?
But the thing is, abusive husbands aren't bad all the time either. From time to time they know how to be sweet and seem to care: one present here, flowers the next day, a little bit of gaslighting, and fake apologies after that "accidental" slap.
Given enough time (if the wife is still alive), at some point the victim decides to leave, and then all hell breaks loose. Trump is the manifestation of that moment. He does not represent a change in #USA's nature, but a hidden side that was "always" there, just waiting to play its role.
Others believe this is because #US citizens have been intentionally dumbed down by a combination of propaganda and a disfunctional education system, and I'm sure it's partly true... But let's see what many of their most brilliant and educated citizens are choosing to do with their lives today: sfstandard.com/2025/03/12/stan
So, all I'm asking is: please drop the act. It was always a clusterfuck.

Momentan halte ich das für ein Gerücht, aber sollte es sich als wahr herausstellen, chapeau!

PVV-minister wilde op ‘Trump-achtige’ wijze weer overal naar 130 kilometer per uur | Politiek | AD.nl
ad.nl/article/~a1e4e24b/
Ahh ... Van die 1e, 2e en 3e prioriteit om overal weer (eventjes) 130 km/u te mogen rijden is ook al vrijwel niets terecht gekomen... 😂

Eerste, tweede en derde prioriteit’
PVV-minister Madlener maakte meteen na zijn aantreden vorig jaar intern een groot punt van de verhoging van de maximumsnelheid, blijkt uit de stukken. Zo schreef een ambtenaar dat de minister ‘informeel heeft aangegeven dat de snelheidsverhoging zijn eerste, tweede en derde prioriteit is’.

Gegen 20:30 Uhr soll in #Coburg ein ganz heftiges Gewitter vorüberziehen.
Woher ich das weiß?
Ich sag mal so, ich steh gerade unter einer Außen-Dusche in Coburg in einem Garten und da spürt man das irgendwie.
