I utilize a software suite called Pi_Star
Pi-Star is a custom, pre-configured SD Card image for the Raspberry Pi computers for using many different digital radio modes on a hotspot.
I have Brandmesiter talk group 3136728 linked to my Allstar system.
My portable DMR hotspot is a Jumbospot with a Raspberry Pi zero w.
My home hotspot is a DVMega on a Raspberry Pi 3 that is also using the Pi-Star software.
Above is the dashboard of the portable pi-star hotspot.
