If you are looking for a Zumstar + PiSpot setup guide for DMR, then KC6N has made a great tutorial that is available here as a .PDF: https://www.hamdigitaal.nl/download/algemene-informatie/ZumSpot_Pistar_KC6N_20180605.pdf Full credit goes to KC6N, I have taken the liberty to link to the site where this document is available to help other amateur radio ops get on the air with their hotspot setup.
