Picard engineering tip: Use the metric system.

How do folk refer to computers in their house?
We've always called them machines, as in

"Has anyone seen my machine?"
"The machine needs rebooting"

This terminology goes back to the huge clunkers the kids used right up to modern sleek fondle blocks.

Borrowed my climbing partner’s rack last week, and I love the way my closet looked! 🤩

#NanoVNA-saver - how to enable values (indexes, labels, whatever you call them) on the lines on the Smith chart?

Lowest SWR or resonance?

(Given that a resonant 1/4 vertical has 36 ohm impedance)

Now I am a nanoVNA wrangler I can tune the elements on my DX Commander for resonance, but around 1:5 SWR; or under 1.1 SWR, but not resonant.

Which is best?

Why Maidenhead Grid Squares?

Google maps doesn't know about them.

What's wrong with plain old Lat Long.

At least you can eyeball Lat Long and get some idea where it is.

I can't find for sale anywhere a 1:4 #balun for HF. It is for a low height 40m inverted V #NVIS #antenna. Military versions such as #AS-2259 use the custom coax support pole as an impedance transformer.

To be clear, I mean 12.5 ohm balanced antenna side to 50 ohm unbalanced coax side. The ones for sale on eBay/Amazon seem to be mislabeled 4:1 ones.

Making one isn't an option: my hands don't work properly.

Anyone any ideas.

Picard management tip: It takes hard work to become a master at single-tasking.
Perhaps the top person at The Atlantic was added to the Signal chat because those on the chat believed there was a person in charge of the Atlantic.

I wonder if they respond to Signal's "please donate" messages

"The Atlantic magazine's Jeffrey Goldberg reported that he had been added to a Signal message group which apparently included Vice-President JD Vance and Defence Secretary Pete Hegseth."
