We went and met Shane and Liza for brunch at Karen's, then Shane and I went to the airport and carried on working on his plane. We had everything set up and working, but it was quiet, so we ass-u-med it was the really high gauge (so, uh, thin) wiring that was on the radio, so we pulled the radio wiring and went home - Shane's going to install thicker wire and we'll try again.
I'd been asked to join a conference thing by Insta360, and I thought it was something to do with the cameras. It wasn't, it was feedback about their web site. I stayed on, and now it looks like they're going to send me a battery, a selfie stick and a bicycle mount :o)
