The Chebychev Filter Calculator. Nice to bookmark.
« on: July 10, 2025, 1949 UTC »
I came across this bookmark, after forgetting about it for the last few years, and it does get you into the ballpark in calculating L & C values for a Chebychev Filter.  http://www.calculatoredge.com/electronics/ch%20pi%20low%20pass.htm  Get those harmonics and spurs under control.

“I am often asked how radio works. Well, you see, wire telegraphy
is like a very long cat. You yank his tail in New York and he
meows in Los Angeles. Do you understand this? Now, radio is
exactly the same, except that there is no cat.”
-Attributed to Albert Einstein, but I ripped it from the latest Splatter .PDF March 2025 issue.

'It's better to give than receive' so why Rx when you can Tx!

Better?

Actually, yes. I prefer the one you posted. More topology choices and variable termination impedances wins me over. I see it used a lot in professional areas too.
