Raspberry Pi repeater controller

Aaron Crawford, N3MBH, is in the process of designing a repeater controller using his Raspberry Pi. He’s moved into testing on the RPi and toward designing and refining the circuitry for the radio interface.

What makes this different than other projects I’ve seen is the polish of his web interface. You can tell he’s a web developer — it’s definitely slick!

Aaron describes the project here:

In setting out to develop this project my primary goals and features are to develop a low-cost, low-power, but feature rich duplex repeater controller suitable for setting up a temporary / emergency repeater systems with radios that can be run on portable power. However with a more complete feature set and a modular design, it could also be used as a primary or a backup controller for a permanent installation repeater. With the low cost, modular design, it would make it easy to keep backup hardware (Raspberry Pi, repeater control board, and a cloned SD card) on site for easy service swap-outs.

This is definitely a project to keep an eye on. Kickstarter, anyone?

  • Wow, it even plays a nice funk groove in the background! 😀

    I’ll keep an eye on this project. I can see, in an emergency, a repeater being setup with a controller and a couple of mobile radios.

    I would be interested in help with this project. I go back with Linux to the very beginning. I have a Rpi and also the primary trouble shooter for our club repeater.

    thanks and 73

  • Ron KB5YT:

    Just curious if it was ever finished and are you ready to share?

  • Jim Ashby K5JCA:

    I was in the process of developing the same project and wanted to know if your code is available, I can start with, or if you have completed the code for the project?
    I am here to assist if needed.

    I have yet to get a RPi 3+B, but the question is this: Why not take DMK Engineering’s schematic of their USB to Radio Interface,, then relay it out to where it will fit on top of the RPi, while maintaining a D-25 female connector’s pinouts. This will be a full package of URI with computer having a one unit between the internet (if on wishes internet accessibility) and the radio/repeater.

    I use to work at Texas Instruments and saw many such ‘Reverse Engineering” done on other projects.

    Thoughts, folks. email is good on QRZ.

    Can you let me know where I can buy the board ready-made by any chance??
