Week 2

This week I continued my research on digital repeaters and software. I’ve decided to use a Raspberry Pi with the Pi-Star image, which contains software used to setup, configure, and maintain a digital repeater. It’s the most complete package I’ve seen and is widely recommended by other hams running digital repeaters. I have worked with this particular software package before so I have some understanding of how it works and how to use it. It basically contains many pieces of software which work together to manage and control a digital repeater. It can also be used to control digital multimode hotspots (duplex or simplex hotspots).

Pi-Star contains the popular digital radio software created by Jonathan Naylor, G4KLX: ircDDBGateway, DSTARRepeater, DMRGateway, and MMDVMHost. It also contains a complete dashboard and can support a wide variety of hardware. MMDVM stands for Multi Mode Digital Voice Modem.

The Raspberry Pi is a great piece of hardware for projects like this due to its cost, reliability, availability, and small size. I will be using the one I have already, a Pi 3B.

I am a graduate of the University of Pittsburgh at Bradford. I earned a B.S. in Computer Information Systems & Technology with a minor in Digital Graphic Design in Dec. of 2018. My focus is on computer repair and web design. I also earned my extra class amateur radio (ham radio) license in 2008. I am currently working on DSTAR repeaters, helping other hams, get their systems running, and maintaining a local DSTAR repeater (KC3ESS).
