Operating an RPi Hotspot While Mobile
I’ve been experimenting with reaching a distant Yaesu System Fusion repeater system while driving in my pickup. I’m succeeding at this without bridging through an intermediate repeater.
I built a small hotspot around a Raspberry Pi Zero 2 W board and an MMDVM hat. This is stuck to a USB power bank with some tape. The power bank is sufficient to run the RPi for more than 24 hours. That package sits in a silicone tray on the dashboard.
Alongside it is a cellular hotspot. The RPi unit is connected to the cellular hotspot by wifi.
My mobile C4FM rig in the truck is set to the frequency of the RPi unit. And that’s all there is: a mobile radio, a cellular hotspot, and an RPi-based hotspot attached to a USB power bank.
It’s working well.
I have been interested in the natural world since a very early age. My first career as a mining and exploration geologist took me around the world. In 1992, I began to focus on the conservation of natural resources. I enjoy sailing, working with WordPress and Linux, and amateur radio. It probably goes without saying that I also like to travel!
