The gr-osmosdr project is looking for maintainers:
I am pleased to serve the next year as the first alternate Director, and plan to do more listening and counseling than activism in that role. While I am a longtime member of AMSAT, I am still newly active in this field and have a lot to learn.
Congratulations to @firstname.lastname@example.org @WD9EWK@twitter.com @email@example.com and @firstname.lastname@example.org for winning seats on the AMSAT-NA Board of Directors. Was humbling to be considered with them, @PRStoetzer@twitter.com @WE4Bravo@twitter.com and AB2S. I am hopeful that all of us will continue to advance the cause as best we can.
Someone made exactly what I’ve been looking for to practice listening to CW! Listened to a bunch of this in the background today.
This little section showing how equations for combining series and parallel conductances can be derived from Kirchhoff's laws together with Ohm's law made a bunch of key relationships click for me:
I really want to know how this was done.
How did we physically draw up and reason about circuit designs before computers could compute SPICE simulations and all that?
Could you please retweet to see if we can reach someone who knows the old techniques?
Me, an RF engineer, hiding under the bed:
Armed robber: Good VSWR means a good antenna
Me, busting out from under the bed: ACTUALLY VSWR is only a measure of impedance match & doesn't account for current flow or field distrib-- aw crap https://twitter.com/JacquelynGill/status/1168906816350314498
