My Ham Radio Talk on MeshCore Doubled as a Real-World Test of My AI Note-Taker

I started my RARS talk with a radio conversation.

I brought up MeshCore, sent a message over the air, and made contacts with Tony, Finn, and Av. There was no internet in the middle of it. Then I showed a portable repeater built from off-the-shelf parts, tucked into a 3D-printed case with a LiPo battery.

Only after that did I start the slides.

That was the evening’s subject in miniature. MeshCore is interesting as a protocol, but RDUMesh is interesting because people are actually putting the pieces somewhere, powering them, maintaining them, and making the network useful.
