JS8Call im Notfunk – wir suchen 3–4 Funkamateure, die diese digitale Betriebsart für die überregionale Notfunkkommunikation (Distrikt/Bund/international) testen und bewerten. Auch auf IARU-R1-Ebene wird JS8Call für EMCOMM diskutiert – wir wollen anschlussfähig sein. Interesse? → [email protected]

As someone on whom considerable amounts of energy have been spent to make him somewhat intelligent, I can now claim I can offer AGI at 1 ‰ of the financial effort that OpenAI and Microsoft need:

The moment someone gives me 100 mio. dollar, I'm fulfilling my definition of having reached general intelligence.

Considering this is a 99.9 % more efficient approach than Altman offers, I'm expecting VC offerings to absolutely annihilate my inbox the moment this post goes live.

So far, I've only really been involved in SSB, FM, and CW, but from now on, I'm going to make it a rule to boycott proprietary modes. Amateur radio should be open.

And I also consider modes whose developers disregard the GPL and do not publish the source code to be proprietary, just saying. #hamradio #foss

A half-wave dipole for 20 m also covers 30 and 40 m with a tuner. Use it for 60 or 80 m? Bad things start to happen.

Short dipoles are attractive for city dwellers like myself! But to feed them, high voltages AND fairly high currents are required. Losses become an issue.

I developed FLOSS Python code to run nec2 antenna simulations automatically. I showcased it studying relevant aspects of dipoles as they become shorter and shorter.

Good fun. I learned a thing or two.
