On Thursday, December 12th, 2019, I was invited to speak at the NDSU Amateur Radio Society (where I am the technical advisor and trustee of their D-STAR repeater) as part of their Ham Radio Seminar series. I discussed Digital Repeater Modes (Yaesu Fusion, D-STAR, DMR) as well as AREDN.
Overall the presentation was well received. You can see the entire slide show below. Enjoy!
