  • CubicSDR on Raspberry Pi OS (64-bit)

Notes from practice

I use this site to document systems, configurations, and lessons learned as I work through real problems—both professionally and through personal experimentation. The goal is clarity: understand how something works, explain why it behaves the way it does, and make it reliable and repeatable.

If you have questions or comments, you’re always welcome to contact me.
