I enjoyed watching on YouTube Patrick Wood as the Keynote Speaker at the AMSAT-UK 2025 annual colloquium this morning. He did live demonstrations of his CubeSat Simulators which was awesome!

Had a mild-but-annoying cold all weekend, but worked on some projects.
My ‘connect your Morse Key to Discord’ boards are now with JLCPCB for assembly.
And I designed a servo controlled ‘analog dial gauge’ for the CubeSatSim project.

@ku2y Hi!
I've been playing with a CubeSatSim that the RSGB have lent me. It's been rather a lot of fun so far.
Do you know of anything that can decode the BSPK telemetry that isn't FoxTelem? I'd ideally like to hook it up to MQTT so I can build a visualiser for it.
Also I've wired up the INT […]
