This box does one thing.
One way.
Forever.
I don’t like that.
In this video, I take a $500 “dumb” repeater and replace the proprietary controller with software, a $30 Raspberry Pi, and a home-built interface cable. No locked menus. No vendor software. No magic boxes.
This is not a GMRS tutorial and it’s not about rules, brands, or menus. It’s about a pattern:
when the controller becomes optional, everything changes.
If you’ve ever looked at a piece of hardware and thought “this should be software”, this video is for you.
