Even as a #radio enthusiast, I've had massive problems really understanding the notion of #impedance. I can do the math, but it doesn't really internalize, and I'm always thinking about it in a manner similar to having to use tongs to do a jigsaw puzzle.

Until yesterday, when someone describing why an explosion in the air doesn't move into water easily, and the same for an explosion in water:

It's an impedance mismatch.

And the scales fell from my eyes.

This is the RF choke I made a while back, thought I'd share it. It's attached to the bottom of my homemade fan dipole.

I'm actually really proud of it, it's the first one I've had, I made it by hand and it works great- has done for a year now, on all bands from 80 to 10.

I want a 3D printer.

I don't really NEED one, mind you.

I do want one, though.

The Duke is my supervisor for my radio activities.

An #introduction- I'm Corey, a ham from Washington State.

I restore old tube rigs and SWL sets as a hobby, along with fixing up newer solid state gear.

I run a TS-820S and a TS-130 at the moment, and can usually be heard in the evenings at 530 PT on the WARTS net at 3975 on 80m.
