I think I'm finally starting to understand the reactance part of #impedance . You can increase the reactance by adding an inductor (X = jωL; ω = 2πf) and lower it by adding a capacitor (X = 1/(jωC)). You can use networks of variable capacitors and inductors if you want to adjust that (which affects SWR) while transmitting at the frequencies you want. :3c
And once you're done, you can replace those with fixed capacitors and inductors because you'll know what works! :D

And it's friday again, time for #newstodon. Established by @gbhnews and promoted by @TexasObserver to promote great work from newsrooms here in Mastodon.
This time with an article from @ghonsel:
Longer life for used batteries
Many old batteries can be saved by replacing individual cells. A new process makes it possible to assess more quickly whether this is worthwhile.
