Looking for #AmateurRadio antenna feedline common-mode choke advice.
I'm currently running a 40m EFHW for 40m, 20m, 15m, and 10m, and my noise floor is high, especially north of 40m. Someone in my local club suggested 25' of coax wrapped around a 4" PVC pipe, but http://www.karinya.net/g3txq/chokes/ makes it look like air core CM chokes are fairly narrow bandwidth and high in reactive impedance, so not obviously best for a single EFHW working those bands.
It looks like a line of 10 FB-31-1020 ferrites would give me >1k primarily resistive impedance over that swath of the HF spectrum, and so be a good match for the antenna I'm using.
Any #HamRadio folks have thoughts on that? Am I crazy? Do I misunderstand? I'm just a baby ham... 😀

Trump will be the oldest president ever and is already showing cognitive decline. Yes, he'll be in the White House, but probably not in the driver's seat. I think that's why Elon Musk worked so hard to elect Trump and to position himself within the administration.

- Screenshot of student's "work". Ethical considerations of using AI for homework Using AI for homework raises ethical concerns about academic integrity and personal responsibility. While AI can help with learning, leaning too heavily on it without actively engaging with the information can hamper comprehension. Ethically, it is critical to employ AI to support learning rather than replace personal effort or undermine academic integrity. (remote)

18 November 1942 | 44 Poles transported by Germans from a Pawiak prison in Warsaw were registered in the Auschwitz camp. Number 75886 was given to a 20-year-old Wiktor Tołkin. He was released from the camp in February 1944 thanks to his family efforts.
After the war, Wiktor Tołkin became an architect and a sculpture. He is best known for his monumental sculptures built in memory of the victims of the German concentration camps in Stutthof and Majdanek.

“One day, a student noticed something strange: One of the rats in the group trained to expect positive experiences had its tail straight up with a crook at the end, resembling the handle of an old-fashioned umbrella.
I had never seen this in my decades of working with rats. Reviewing the video footage, we found that the rats trained to anticipate positive experiences were more likely to hold their tails high than untrained rats. But what, exactly, did this mean?”

“Curious, I posted a picture of the behavior on social media. Fellow neuroscientists identified this as a gentler form of what's called Straub tail, typically seen in rats given the opioid morphine. This S-shaped curl is also linked to dopamine. When dopamine is blocked, the Straub tail behavior subsides.” [2/2]

@dymaxion @futurebird @whknott Where I wish people understood calculus is in *political* discussions, particularly involving economics. Not any of the techniques, just the basic idea of a function, its derivative and its integral being different things.
And maybe the idea that if you have a function of multiple variables, its rate of change is going to depend on which specific things you're holding constant.
But that last one is a HARD idea. It doesn't even really show up in AP Calculus, it's a later class. It trips people up when they're studying college-level thermodynamics.
