Please note that all of the Pi Star and MMDVM posts prior to this post are now about 4 years old and may not apply or work for Pi-Star anymore. The general idea is still good, but things have been updated in Pi Star and may not work the same way anymore.
If you follow these directions, you do so at your own risk (physical, software, sanity).
If something fails to work the way it should, feel free to contact me and I will try to help, but I make no guarantees that I can help you. I haven’t kept up with Pi-Star much since my friend, Ted, passed away. I managed his repeater that used Pi-Star for a DSTAR link. After his passing, I setup a DSTAR hotspot, but I don’t tinker with it anymore. Ted was always the one who wanted to tinker and make it do new things.
