[03:00] <Ian__> Look for "Ultimate Lithium Energizer" on the battery/packaging. Boost regulator to make the flight with 1 x AAA.
[03:01] <Ian__> They are expensive, but the only one for the job. Do your testing with other batteries and save the good ones for live flights only.

[23:54] <purewhite[m]> Brisbane's radiosonde looks like it might land on the land today. Just a long way from me still :(
[23:55] <purewhite[m]> I got caught out with auto_rx.sh last night. Left it running to try and track the 3am flight, didn't realise it auto shutdown after 3 hours. I know, it says to use the systemd service file, but this is still my laptop and not my dedicated pi
[23:59] <purewhite[m]> Another station is on the hab tracker, VK4WJR. also running radiosonde_auto_rx. They are closer, but not managing to pick it up
