Something like a FT240-43 toroid should work for 80m to 10m.

That is to make a common-mode choke on your feedline. You can always try to improve the RFI emissions from devices in your house by snapping on some ferrite on wall warts etc.

They're mainly doing it to deny India and Bangladesh access to their largest river. It's not like people need fresh water to live, right?

The main job of the unun is to match the impedance of the wire to the 50ohm feedline. You may or may not need a common mode choke to prevent RFI, but I had a lot of RF problems with my 40-10 EFHW. My radio was fine but my computer started to glitch out when was transmitting. That all disappeared once I looped my feedline through some ferrite.

Awesome! If you do plan on transmitting (on 10m), I recommend a common-mode choke on the feedline between your radio and the EFHW. All you need is a ferrite toroid and loop the feedline a few times through it. This can prevent RF going into your shack, which is kind of a thing with EFHW antennas. Otherwise EFHWs can work very well. Have fun and enjoy your new radio.

FWIW I have never been bothered by a little cosmetic wear.

And people pay extra these days to get a "relic"ed guitar. Make of that what you will.

This particular money has its own Wikipedia page: https://en.wikipedia.org/wiki/Siege_money_(Newark)

Do you really believe the US Senate cares about 75 Nobel Laureates?

The continued existence of police forces in the US depends on their role as protector of the wealthy. They know they must perform their duty or risk losing the protection of their patrons.

I unfollowed Alec on Fedi because every other post would be him complaining about his interactions on there. Reply guys. Trolls. Lack of algorithms which raise some of the better comments out of the drek. Insufficient moderation. Etc. This got boring and depressing to read about honestly.

However I think he's totally right. Mastodon/Fedi works well for certain kinds of people. People with limited engagement, people posting mostly uncontroversial things, and perhaps people who just don't give a shit. But for high-visibility folks like Alec the old-school unfiltered discourse seems really uncomfortable.

It has little to do with federation itself, I think. But if Mastodon ever added the choice for users to enable "modern social media algorithms" for their view of their feed I suspect it would work a lot better for many people.

The same thing we do every night, Pinky: Try to take over the world!

Seeing this photo made me think "Man, execution by hanging is still pretty harsh"

"Rudolf Heinrich Suttrop, SS-Obersturmführer, Adjutant of the camp commander, Dachau"

Oh.
